How Long Should A Salt Water Pool Pump Run?

How many hours to run your pool pump each day

  • Changes in the amount of hours you operate your pump each day can have a big and positive impact on your overall health and well-being. The following appear to be the most commonly used numbers: The winter season is 4 hours per day, whereas the summer season is 8 hours per day.
  • A minimum of two times each day should be spent circulating the complete volume of water.
  • The goal for your pool water is to ensure that it is kept in a safe and balanced state, which is primarily determined by: a sufficient level of chlorine (or other sanitisation mechanism) to control algae growth
  • a sufficient level of calcium (or other sanitisation mechanism) to control algae growth
  • and a sufficient level of magnesium (or other sanitisation mechanism).
  • PH and Total Alkalinity must be maintained at steady levels.

If all three of the aforementioned factors are true, your pool is unlikely to become green.

What determines how many hours filtering my pool needs?

  • The number of factors that differ between various pools is so huge that it is impossible to anticipate such broad figures to come even somewhat near to what is truly necessary for each pool in the first place. Consider: An increase or decrease in the number of leaves and grass or any other organic substance. A pool that is surrounded by grass and trees will have far greater needs than a pool that is encased in a concrete bordered patio.
  • When it comes to swimming load, a youthful family in a warm environment will have a greater burden than a senior couple in a colder region.
  • Irrespective of whether you have a pool cover in place
  • Whether or not swimmers should shower before entering the pool
  • This includes whether or not the pool is exposed to direct sunlight in a windy place or whether or not it is in a shaded protective position.
  • The size of the pool pump that has been installed, and hence the amount of water that has been pumped
  • When it comes to the plumbing between the pool and the pump/filter, the length and number of bends will have an impact on the effectiveness of the pump and, consequently, the volume of water pushed.
  • Whether of not the pool is chlorinated with a salt water chlorinator or with chlorine pills

All of these variables will have a significant impact on the length of time the pump must run on a daily basis.

What does changing the hours per day of pumping do?

Because salt water pools are the most prevalent, I’m solely taking them into consideration here. If you consider all of the elements listed above to be constants for your pool (they remain constant regardless of the season or degree of usage), the number of hours you operate your pump has the greatest impact on the chlorine level. The pool pump performs two functions.

1. Debris / Particle Filtration.

In order to accomplish this effectively, you must operate the filter for an amount of time each day that is sufficient to pump a volume of water equal to the whole volume of your pool. To figure out how long this will take, do the following:

  1. In order to accomplish this, locate your pump’s manual, or if you don’t have one, look at your pool pump and note the model number, then hunt for it online.
  2. The handbook will state how many litres per minute (lpm) the pump is capable of pumping at any one time. It is possible that the real output will differ depending on your plumbing and pump placement, but the value in the instructions is near enough.
  3. Calculate the size of your swimming pool. The dimensions are as follows: length x width x depth. If you have a pool that is an unusual form or has a fluctuating depth, simply pick an average value. To get the volume in cubic meters, multiply the dimensions in meters by the number of cubic meters (m3). In order to get the volume in litres, multiply the number of cubic meters by 1000 to get the total volume in litres. Backyard pools normally hold between 40,000 and 100,000 litres of water
  4. now figure out how many hours it will take to pump the whole amount of water in your pool. Consider the following scenario: you have a 60,000 L pool with a pump that runs at 200 Litres per minute. 60,000 divided by 200 equals 300 minutes, which is divided by 60 equals 5 hours.

You have now completed the bare minimum of hours necessary to filter the debris from the water in the pool, if any.

2. Chlorine production

The second task performed by the pool pump is to circulate the water through the chlorinator.The chlorinator is made out of a metal plate that is coupled to an electrical circuit to produce chlorine.Some of the salt in the water is converted to chlorine as a result of this process.You must operate your pump for a sufficient number of hours each day in order to create the necessary quantity of chlorine.While some chlorinators will automatically shut down when the goal amount of chlorine is achieved, some chlorinators will not.

  • Check your chlorinator’s handbook to see which one you have.

Working out your minimum number of pump hours

You have a larger error margin with a longer filter run time, but you also spend a lot more electricity.Experimenting with different settings and taking into consideration the usage, environmental, and seasonal elements that affect your particular pool is necessary to get a satisfactory balance in the end.The more your understanding of how the water chemistry of your pool works, the better equipped you will be to optimize the power usage of your system.Here’s the procedure I use to determine the bare minimum amount of hours I’m comfortable with the pump running:

  1. Find a place to keep track of the important numbers. I’ve discovered that a notes app on my phone is the most effective
  2. Test the water in your pool on a weekly basis with a test kit and keep track of the following: Total Alkalinity
  3. Free Chlorine
  4. Total Alkalinity
  1. Do this for at least two to three weeks to guarantee that your results remain constant.
  2. Consider cutting back on the amount of hours your pump operates by, say, one hour each day while still keeping the bare minimum necessary to filter your water once every 24 hours.
  3. Check to see if your free chlorine levels are still high enough
  4. if they are too low, you will need to increase the pumping time.
  5. Once they have reached a stable state, you will have reached your seasonal minimum. If you reside in the southern portions of Australia, you will use far less filtering during the winter months than you will during the summer months. While you could adjust your pump hours three to four times a year, I believe that having a winter and summer setting is the most practical
  6. When the seasons change, repeat the procedure outlined above.
  7. Importantly, make a note of your settings so that you may revisit them later on.
  8. Keep an eye out for the other changes in circumstances described at the beginning of this piece, which might have an impact on how much filtration and chlorine your pool requires.

Pool Pump Timer and Salt System Run Times

With a pool pump timer, you can manage the operation of your pool, as well as the run-time schedule for your pump and other pool equipment like your filter, heater, and salt system.The amount of time you spend operating your pool system may be controlled, allowing you to save money while also reducing the amount of time you spend maintaining your pool.They can be counted on to maintain your pool or spa system functioning smoothly and efficiently throughout the season without causing you any problem.We all want to spend more time in the pool, relaxing in the sun, and less time worrying.A timer can assist by managing all components of your pool system, allowing you to spend more time enjoying your pool and less time worrying.

  • They provide pool owners with the opportunity to regulate everything at the same time, and in certain situations, they may even help to extend the life of your gear while also improving the general health of your pool.
  • In addition to automating the primary components of your pool system, an electrical timing device may be used for a variety of different tasks.
  • Automation systems for your hot tub system, water features, lights, and just about everything electrical surrounding your pool or spa may be implemented with them.
  1. You can operate your entire pool from practically anywhere by simply pressing a button on your smart phone, tablet, or computer, thanks to some of the pool automation systems currently available on the market.
  2. A salt water pool increases the need of automating your pool system even further, as the salt water system will not create chlorine unless water is continuously circulated through the cell.
  3. It is possible that some salt systems include timers or control panels, but it is also possible that others do not, in which case an external pool pump timer will be required.

We’ll go through salt water system pool run durations in further detail below, as well as which systems require an external timer, as well as our suggested pool pump timer recommendations.

Salt System Run Times

  • Using a pool pump timer, you may regulate pool operation or set a timetable for your pump, filter, heater, and salt system to run on a specific period of time each day. By controlling the amount of time you spend operating your pool system and reducing the amount of time you spend maintaining your pool, you will save money. This means that you can rely on them to maintain your pool or spa system operating smoothly and efficiently throughout the season with no effort. We all want to spend more time in the pool, relaxing in the sun, and less time worrying. A timer can assist by managing all components of your pool system, allowing you to spend more time doing what you love and less time worrying. Owners of swimming pools will appreciate the ability to regulate everything at the same time, and they may even find that their hardware will last longer and that the overall health of their pool will improve. An electrical timing device may be used for a variety of tasks in addition to automating the major components of your pool system.. Automation systems for your hot tub system, water features, lighting, and just about everything electrical surrounding your pool or spa are available. Some of the pool automation systems on the market allow you to operate your whole pool with the push of a button from practically anywhere using your smart phone, tablet, or computer. A salt water pool increases the need of automating your pool system even further, as the salt water system will not create chlorine unless water is constantly flowing through the cell. Some salt systems have timers or control panels built in, while others do not, necessitating the use of an external pool pump timer to keep things running smoothly. We’ll go through salt water system pool run durations in further detail below, as well as which systems require an external timer, as well as our suggested pool pump timers.
  • Pool usage
  • Rain
  • Indoor or outdoor 

Set your system to operate for 8-12 hours every day, with the chlorine output on the generator set to 50 percent of its maximum capacity.After many days of testing and determining the free chlorine measurements, only the generator’s output should be adjusted.By keeping the pump’s operating duration constant, you will be able to see how modifying the chlorine output will impact the amount of chlorine produced in your pool.As previously stated, the goal is to keep your free chlorine levels above 2.0 parts per million (ppm) and below 4.0 parts per million (ppm), and because this fluctuates depending on the variables listed above, it is recommended to keep written records initially, especially if you find yourself using the super chlorinate feature more than once per week.The usual pool system requires between 4 and 10 hours of operation, therefore you will need to evaluate this for yourself by conducting tests over a period of time.

  • Increasingly popular are variable speed pool pumps, which have the capacity to work at low energy rates for extended periods of time while remaining quieter, more energy efficient, and improving the health of your pool.
  • Variable speed pool pumps are also more environmentally friendly.

Which Pool Timer Should I Use?

  • The process of selecting the best pool pump timer for your pool should begin with an examination of what you wish to regulate or automate.
  • When it comes to timers, the most simple will just switch on and off a single pump, but more advanced timers will modify the speed of your variable speed pump and manage virtually everything electrical in your pool system.
  • Other variables to bear in mind include the amount of horsepower you need to regulate, the maximum number of amps that may be used, and the number of devices you wish to control.
  • A typical HP capability is between 2 and 5 HP, which is more than sufficient for the majority of home pool applications.
  1. Also prevalent are timers that can handle up to 12 devices, allowing you to automate just about anything that keeps your pool running smoothly.
  2. For use with variable speed pool pumps, a timer that can switch between high and low speeds will be required.
  3. The Intermatic T106R timer will assist you in regulating your pump; but, if you wish to be able to manage the ON/OFF setting of your pump using a timer, you will also need to acquire the T104.
  4. If you live in an area where freezing temperatures are common, you may want to consider using a pool pump timer that has freeze protection.
  1. Intermatic’s PF1102 pool timer is designed to be used in combination with an existing timer to prevent freezing damage to the pool by automatically turning on the pump when the ambient air temperature dips below the value specified on the thermostat.

How Long Should I Run My Saltwater Pool Pump?

  • A pool pump is used for a variety of tasks.
  • It pulls water from the pool, sends it through the filter to be cleaned, and, in the case of a saltwater pool, sends it through the salt chlorinator, which turns salt into chlorine to sterilize the water once it has been converted to chlorine.
  • It then returns the water to the pool, and the cycle repeats for as long as the pump is operating at full capacity.
  • It is common for salt chlorinator manufacturers to propose that you operate your pool pump for 8 hours each day, and that you do it during the warmest portion of the day while the sun is out.
  1. UV radiation from the sun, as well as impurities introduced into the pool by people swimming in it, trash falling into the pool, and rainfall, all destroy chlorine in the pool.
  2. It is only when the pump is working for a fair period of time that enough chlorine can be created by a saltwater chlorination system.
  3. Specific to this, the maker of your chlorinator will most likely advise you to operate the pump for a long enough period of time each day to ensure that every drop of water in your pool is circulated through the pump.
  4. So, if you have an 18,000 gallon pool, you want to make sure that all 18,000 gallons are drained out each and every day.
  1. It is possible to calculate this by calculating how many gallons per hour (GPH) your pump processes and dividing that value by the pool’s size.
  2. If you have an 18,000 gallon pool and you use a Hayward SuperPump capable of pumping 3,660 gallons of water per hour, you must run your pump for 18,000/3,660 = 5 hours each day.
  3. In this case, 8 hours of pumping time should be more than sufficient.
  4. However, even while the pump is running, it is possible that the chlorinator is not truly operating.
  5. Modern chlorinator systems may be programmed to create chlorine only while the pump is working, with settings ranging from 0 percent to 100 percent of the total pump operating time.
  6. It is determined by the percent settings how much of each day’s time the pump is scheduled to run.

Consequently, if you set the chlorinator to 50% and run your pump for 8 hours each day, the chlorinator will run for 50% of that time, or 4 hours.When the pump is turned off, the generation of chlorine is halted.When the system reaches its predetermined point, however, the pump can continue to operate while the chlorine production is turned off.Start your salt chlorinator system at 50 percent capacity and modify it as needed until you reach your desired level of performance.Given that the salt and other pool chemistry are within acceptable limits, you would increase the setting percent to create more chlorine and decrease the setting percent to produce less chlorine, as appropriate.You may want to increase the chlorinator setting during the hot summer months when the pool is being used more often, and decrease the setting during the cooler summer months when the pool is being used less frequently.

Using test strips, physically check your chlorine levels once a week, or more frequently if necessary, to verify your pool settings are appropriate for the conditions.

Chlorine Production

  • Swimming pools become more hygienic and clean when the temperature decreases, which means less chlorine is necessary.
  • According to Hayward, which is a manufacturer of pool pumps, chlorination systems, and other types of equipment.
  • As the temperature decreases, so does the percent setting of the chlorinator system, as well as how the system adjusts chlorine production to reduce chlorine output: At 60 degrees Fahrenheit, the output is scaled back to 20 percent of the desired output level.
  • When the temperature reaches 50 degrees Fahrenheit, chlorine generation ceases.
  1. Owner’s handbook for the Hayward AquaRite Once a result, as the temperature goes below 60 degrees, the chlorine production decreases automatically since less chlorine is necessary to keep the pool clean.
  2. When the temperature dips below 50°, chlorine production is fully halted because the salt cell might be destroyed at such a low temperature, the pool requires minimal chlorine at this point, and salt does not convert properly to chlorine at such a low temperature.
  3. Modern chlorinator systems take temperature into consideration in order to avoid over chlorinating a pool, which can over time damage equipment and cause a salt cell to fail prematurely, necessitating the replacement of the cell.
  4. In the short term, a too chlorinated pool may also cause irritation to the eyes and skin, which are two things that you should avoid if you have a salt water pool with chlorine levels that are within acceptable limits.

Salt Levels And Chlorine Production

  • It’s critical to keep the salt level in your saltwater pool at an appropriate level in order to guarantee that the pool produces enough chlorine.
  • If there is insufficient salt in the system, the system will be unable to create enough chlorine, causing the water to get hazy and eventually algae to bloom.
  • Excessive salt can cause damage to pool equipment as well as other undesirable side effects.
  • Modern salt chlorinator systems are equipped with a built-in capability that detects excessive salt levels and sends you an alert so that you may take appropriate action.
  1. In addition, if the salt levels go too low, they may shut down automatically.
  2. A saltwater pool should have a salt concentration in the range of 2,700 ppm – 3,400 ppm, which is optimal.

Adjusting Salt Levels Up and Down

  • In case your salt level is too low, you may use a salt calculator such as this one to figure out how much salt you will need to add to bring the system back up to the appropriate range.
  • You enter the size of your pool in gallons, the current salt level, and the target salt level, then select Calculate.
  • Then scroll down to see how much salt you need to add to your pool.
  • All you have to do now is dump that amount of salt right into the deep end of the pool and wait for it to dissolve.
  1. Depending on the system, certain salt systems will shut down if the salt level becomes too low to safeguard the system, resulting in no chlorine being created until the salt level is increased.
  2. if the salt level is really high (i.e.
  3. 4,000 parts per million or above), you may need to remove some water from the pool to reduce the salt level down and then top it off with fresh (i.e.
  4. unsalted tap water) to dilute the salt level even further.
  1. Generally speaking, emptying 1 inch of water from your pool will remove 100 parts per million (ppm) of salt from the pool.
  2. It might take up to a day for the salt level to return to its target range while the pump is working continuously.
  3. The salt level ranges from 2,700 to 3,400 parts per million (ppm), which is quite a big range, and it can change during the pool season.
  4. More pool use combined with more intense sun and more rain results in a greater need for chlorine, which raises the demand for salt.
  5. Because salt degrades with time, it must be renewed on a regular basis.
  6. A suggestion: Keeping your salt level on the high side – closer to 3,400 parts per million (ppm) than 2,700 parts per million (ppm) – implies that your salt cell will not have to work as hard since there will be more salt available to utilize.

It is less expensive to purchase additional salt than it is to purchase a new salt cell.If the salt level is about 3,500 parts per million (ppm) and it’s early in the pool season, I’m not sure what you should do.Because of evaporation and splash loss, it’s likely that you’ll be adding water to your tank soon, and the salt level will drop as a result.


  • During the summer, a quick and dirty rule of thumb is to operate your pool pump for 8 hours each day for the duration of the season in order to filter the water and create enough chlorine to keep the pool clean.
  • As a result, if the pump is not running, no chlorine is created, and the more time you spend running it, the more chlorine is produced.
  • In order to enhance chlorine output, you may either increase the chlorine setting on your pool chlorinator or increase the amount of time your pool pump runs every day.
  • Alternatively, you could do both.
  1. Increasing the percent setting on your chlorinator will help you if you notice that your chlorine levels are too low.
  2. Throughout the season, you may find that you need to modify the percent setting UP during hot periods and high pool usage, and then adjust the percent setting DOWN later in the season when it’s not as hot and the pool is no longer being utilized, depending on your circumstances.

How Long to Run Your Pool Pump Every Day—And Cut Costs

  • It’s a damn pity that we have to deal with the realities of everyday life.
  • In an ideal world, you’d be able to operate your pump 24 hours a day, seven days a week—at least in terms of cleanliness, it’s not feasible to run your system too frequently.
  • Unfortunately, if you never turned off the electricity to your pump, your energy bills would be nothing short of a nightmare.
  • When it comes to pool upkeep, the rule of thumb is to operate your pump for eight hours every day.
  1. Even if it’s the shortest answer, it isn’t necessarily the most correct.
  2. Other things might have an impact on this figure.
  3. That implies that even if you use your pump for eight hours a day, you might be wasting money without even being aware of it.
  4. With a few short considerations, such as the capacity of your pool, the type of pump you use, and the time of day you run your pump, you can achieve the best balance of pool cleanliness and cost savings—all in a matter of minutes after just a few minutes of reading.
  1. Prepare yourself with accurate information, and time and money will be saved for years to come.
  2. Isn’t this a great deal?
  3. It is the most cheap variable speed pump available, and it pays for itself in energy savings over time.
  4. It also has a lifetime guarantee, making it an excellent choice if you are on the lookout for the finest value available.

“But Why Should I Run My Pump at All?”

  • Your pool pump serves as the central hub of your pool’s cleaning and sanitation system.
  • It ensures that the water is circulated properly, allowing filthy particles to be filtered out of it.
  • It also helps to disperse your cleaning ingredients throughout the house, similar to how you would swirl milk into your coffee.
  • If there is no pump, there is no circulation, which implies there is no cleaning.
  1. No joke: if you left your pool pump turned off for an extended period of time, it would transform into a green pond full of stagnant water and harmful microorganisms.
  2. No, this isn’t exactly what you’d expect to see in a relaxing swimming pool.
  3. Are you fed up with having to stoop and lean in order to scrub the angles of your swimming pool?
  4. Professional-Endorsed 360-Degree Bristles Blue Torrent Pool Brush features a patented design for easier cleaning—and it’s a favorite among pool care technicians all over the world.

Calculate Your Turnover Rate—And Pump Right

  • In order to maintain your pool clean, all of the water must pass through the filtration system of your pump at least once every day.
  • This is referred to as the turnover rate.
  • It’s simple: in order to operate your pump efficiently for eight hours, your pump must be capable of processing all of your pool water throughout that time period, according to the manufacturer.
  • To figure out how long it will take to filter all of your pool water, you’ll need to figure out your turnover rate, which is the GPH (gallons per hour) that your pump claims to be capable of pushing.
  1. For a quick check on whether your turnover rate is profitable, multiply the GPH of your pump by 8.
  2. If the capacity of your pump is optimal for your pool, the following estimate would be accurate for your pool’s volume: 8 times a number equals Is it difficult to estimate how many gallons of water your pool holds?
  3. It’s a math that anyone can perform quickly—even if you didn’t do very well in geometry class in school.
  4. Then multiply the length, breadth, and depth of your pool in feet by 7.5 to get the same quantity in gallons.
  1. That would be expressed as a formula as follows: xxx 7.5 = If you discover that your pump is designed for a considerably larger pool than you have, you’ll want to keep it running for no more than 8 hours each day.
  2. If you discover that your pump is designed for a smaller pool, you’ll want to keep it running for a longer period of time.
  3. What is our recommendation?
  4. You may not like to hear this, but you should get a pump that is appropriate for your pool volume.
  5. In the long term, it will save you a lot of money on your energy bills.
  6. Is your pool pump the wrong size or shape for your pool?

With the Black & Decker 2HP Energy Star Variable-Speed Pump, you can get your pool back on track quickly.It has variable speeds to meet your specific requirements, and it pays for itself in terms of energy savings.

Run Smart for Your Pump Type

Pumps are not all made equal, though. It stands to reason that depending on the kind of your pump, you may need to change the amount of time you spend operating it. When it comes to this issue, the speed and power of the pump are the most significant considerations.

Taking it Slow: Single-Speed vs. Variable Speed Pumps

  • The pace at which your pump runs has an impact on the amount of your monthly energy bill, as well as how long your pump must operate each and every day.
  • Pool pumps have advanced significantly in terms of speed and versatility in the years since its conception, and we couldn’t be more pleased with the results.
  • Single-speed pumps were the first to hit the market, and they continue to be the most basic type of pump on the market.
  • Single-speed pumps have an impeller that rotates at a fixed speed, which is determined by the motor’s speed.
  1. Most of the time, this is a quicker pace than you’ll actually need, and the energy it uses is unnecessarily expensive.
  2. In fact, some states (including Arizona, California, and Florida) have outlawed the installation of new single-speed pumps because they are regarded to be inefficient.
  3. The speed of a variable-speed pump, as opposed to a single-speed pump, may be adjusted to suit the application.
  4. Lower speeds enable water to be filtered more completely while still operating at a far lower noise level.
  1. What’s the best part?
  2. While variable-speed pumps are more expensive than single-speed ones, they will save you more money in the long run than the difference in purchase price—typically in less than two years.
  3. If you have a variable-speed pump, you may find that you need to operate your pump for a longer period of time.
  4. Don’t be concerned; you’ll still save a large amount of money.
  5. Look for a pump that is labelled as a replacement for your current pump, such as this Blue Thunder Typhoon In Ground Single-Speed Pump, if it is time to update but you want to continue with single-speed pumps.

Yes, Horsepower Could Cut Run Time—But Be Careful

  • The amount of work that a motor is capable of performing, not its speed, is measured in horsepower.
  • The more the horsepower, the bigger the amount of water that can be blasted out.
  • Additionally, the more quickly it filters through your pool water, the better.
  • If you’re hankering for a racing car’s worth of horsepower so that you can run your pump for a few hours every day, it’s usually better to take a big breath and think about the facts before making a snap decision.
  1. Horsepower is always a function of the size of your larger pool system, so keep that in mind.
  2. For example, if your plumbing system is comprised of three-inch pipes, it will most likely be able to accept a three-horsepower pump that will operate quickly.
  3. In contrast, if your horsepower is excessively huge in comparison to the size of your pool system, it might waste energy and result in higher energy costs than you anticipated.
  4. Your horsepower should always be powerful enough to spin your pool’s volume at a sufficient rate of around eight hours per day, but not so powerful that it works harder than it needs to—and incurs excessive expenditures as a result of the extra effort required.
  1. Do you have a better understanding of how critical having the proper horsepower is?
  2. Apply your expertise to this Blue Torrent Copper Force Above Ground Pool Pump, which is available in a variety of horsepower strengths to suit your needs.

You Know How Long to Run Your Pump. But What About When?

The most obvious time to use your pool is during the warmest part of the day, and you would be correct. This isn’t entirely incorrect; after all, everyone would want to swim in the cleanest pool possible while they’re really swimming. However, it is possible that it is increasing your energy cost. There is an other route.

Avoid Peak Hours and Save

  • It may come as a surprise to you, but no one genuinely pays a fixed amount for power anymore.
  • During ″peak hours,″ which are defined by electric providers as the busiest periods of the day, the cost of running your pump fluctuates throughout the day.
  • Peak hours are predetermined periods of time during which inhabitants in your neighborhood tend to use more electricity, putting extra strain on the power infrastructure.
  • These hours are determined by the current trends in your particular location.
  1. If you live in a hot environment, it is common for peak hours to occur during the warmest part of the day, when your neighbors are most likely to turn on their air conditioning systems to keep cool.
  2. Dial your energy supplier to find out when the most energy-intensive periods are in your area, and then arrange your pump operation around those times.
  3. Another little-known fact is that you do not have to operate your pump for a whole eight-hour period.
  4. You may divide up the time in any way that works best for your schedule, which provides you a great deal more freedom to run your pump during non-peak hours of operation.
  1. You’ll receive the same level of service for a significantly lower price, which represents a significant cost difference over time.
  2. Looking for a way to reduce your pool operating time while also having a pool system that can handle a bit additional power?
  3. It is recommended that you use this Blue Torrent 1.5 HP Typhoon In-Ground Pump to test it out.

Timing is Everything: Maintaining Your Pool’s Chemical Balance

  • There’s another reason why running your pump during non-business hours would be a better idea.
  • Of course, one of the functions of your pump is to circulate your cleaning chemicals around your pool, ensuring that they are uniformly distributed throughout the water.
  • Anyone who cares about water quality does not want pockets of highly concentrated cleaning chemicals in it.
  • Pool shock is one chemical that has to be applied when the sun goes down.
  1. If you use it during the day, the light will quickly deplete it of its effectiveness, and it will be ineffective altogether.
  2. It is important to operate your pool pump for eight hours at night after adding pool shock to ensure that it is evenly dispersed throughout the pool system.
  3. Are you concerned that your pump’s night shift may interfere with your sleep?
  4. Consider a type that operates at a whisper-quiet level, such as this Blue Thunder In-Ground Single-Speed Pump.

Now You’re Swimming Downstream

You’ve just assured that your pump is efficient at every stage of operation, and all that’s left is to wait for your energy bills to arrive on the doorstep. We promise they’ll be lighter—and so will you. Wasn’t it simple to do?

How To Calculate Pool Pump Run Time

  • If you have a pool, there is a good chance that you also have a pool filtration pump.
  • But for how long should the filter pump be running?
  • In light of the fact that a pool pump filtration system is the second greatest energy user during the summer (behind air conditioning units), we want to make sure that you get the most bang for your money.
  • Let’s go over some frequently asked questions and then go through the math behind determining the optimal pool filter pump run duration for your swimming pool.
  1. We will demonstrate both the traditional computation and a straightforward calculation.

What does the pool filter pump do?

  • It’s critical to understand exactly what your filter pump accomplishes for your pool in order to determine how much running time you require.
  • The pool filter pump is the core of your pool’s filtration system, and it is responsible for cleaning the water.
  • It circulates water from the pool and returns it to the pool, dispersing pool chemicals and purifying your water as it does so.
  • In order to keep your pool water clean, it is advised that you ″turnover″ or circulate it through the pool filter at least once every day.
  1. This will guarantee that the chemicals are dispersed uniformly and that your water remains clean and clear.
  2. Without proper circulation, algae development, as well as water balance and clarity difficulties, are all possibilities.
  3. This might result in water that is dangerous for swimmers to be in.

How many gallons of water are in my pool?

  • Before we get started, let’s figure out how many gallons of water are currently in your pool.
  • Use one of these simple calculations to determine the volume of your pool.
  • When it comes to calculating pool volume, this useful article provides a table that may be used instead.
  • Calculating the Volume of the Pool.
  1. Pools in the shape of squares and rectangles with a single depth: Approximate Volume = Length x Width x Depth multiplied by 7.5 (Gallons) Pools in the shape of squares and rectangles with variable depths: Calculate the approximate volume by multiplying the length by the width by the average depth by 7.5.
  2. (Gallons) Depth on average: The depths of the pool’s shallow and deep ends should be added together and divided by two if the pool has both.
  3. ) For instance, the shallow end is 3′ deep, while the deep end is 8′ deep.
  4. (3) Using the Average Depth calculation, the average depth is (3+8)2=5.5′.) Round pools have a volume equal to 3.14 times the radius times the radius times the average depth times 7.5.
  1. (Gallons) The Radius is equal to the diameter divided by two (or the circumference).
  2. (For example, a 16-foot diameter divided by two equals an 8-foot radius.) It is important to note that most circular pools have a single depth.
  3. Pool Volume Calculation for Oval Pools: 3.14 x Length x Width x.25 x Average Depth x 7.5 = Approximate Volume for Oval Pools (Gallons) For a kidney-shaped pool, multiply the length times 0.45 times the average depth times 7.5 to get the approximate volume (gallons).
  4. (The letters ″A″ and ″B″ represent the width at the two broadest points.) The following formula is used to calculate the approximate volume of irregularly shaped or free-form pools: longest length x widest width x average depth x 5.9 = approximate volume (Gallons)

What is the Turnover Rate?

We can now compute the Turnover Rate based on the pool volume in gallons that we have obtained. Gallons per minute (GPM) is the unit of measurement for water flow rate for all pool filtration pumps, rather than gallons per hour (GPH) (GPH). Follow these steps to obtain the number: GPH = total pool volume divided by eight. GPH minus 60 equals GPM

Let’s do some math!

  • We can compute the run time now that we know how many gallons per minute (GPM) and how large the pool is.
  • The math is straightforward.
  • Consider the following scenario: you have a 20,000-gallon pool with a GPM rating of 40 and a pool pump with that rating.
  • Take out your calculator and just ″sub-in″ your dimensions for the following: 40 gallons per minute multiplied by 60 minutes per hour equals 2400 gallons per hour.
  1. 20,000 gallons divided by 2400 gallons per hour equals 8.3 hours.
  2. According to this scenario, the recommended pool filter pump operating time is 8.3 hours per day for one circulation (or ″turnover″ of water) of the pool.

A simpler calculation

  • A simple rule of thumb for running your single-speed filter pump during the swim season, when temperatures are high and the number of people using the pool are large: If a single-speed filter pump is used, the circulation system should be run for one (1) hour for every 10°F increase in air temperature.
  • For example, if the temperature is 100°F, the pump should be running at least 10 hours each day.
  • If the pool is clogged with algae or if a severe weather event has happened, the pump may need to work 24 hours a day, seven days per week.
  • Pumps with variable speeds: Depending on the operating speed, variable-speed filter pumps should be able to run for a longer period of time.
  1. The majority of pool owners operate their variable-speed pump 24 hours a day (3-4 hours on high speed for the pool cleaning system and 8-9 hours on low speed for filtration).
  2. If the filter pump is running at a low speed, some water features, such as Salt Water Chlorine Generators and heaters, may not function properly or may even fail to turn on at all, so be cautious.

How Long Should I Run My Pool Pump Each Day?

  • Pool owners all across the world appear to be grappling with a straightforward but perplexing subject.
  • How long should I leave my pool pump running?
  • Although the answer to this question is apparently self-evident, many pool owners are unable to grasp the significance of it.
  • As a result, they wind up operating the pool pump all day long or for only long enough to complete one rotation of water.
  1. This precisely becomes an issue for your swimming pool, as well as for your financial situation in general.
  2. You are well aware that having a pool pump running costs you money.
  3. The longer it continues to operate, the bigger the expenses you will incur.
  4. Furthermore, straining your pump to operate harder than it should might cause the pump to wear out sooner than it should.
  1. Running the pump for a short period of time, on the other hand, would not result in a single turnover.
  2. As a result, the water may get cloudy and hazardous to swim in since it is not being circulated properly.
  3. So, how long is the best period of time to leave the pool pump running?

How Long to Run Pool Pump for the Best Result

  • So, how long do you need to leave your pool pump running?
  • In an ideal world, this question might be addressed all day, every day, and at any moment.
  • However, as a result of the repercussions, you must set aside several thousand dollars each month to cover your electrical expenses.
  • To gain a proper understanding of how long you should run your pool pump each day, you must first understand the type of pump you have, the purpose of the pool pump, and the rate at which the pool pump turns.

Type of pool pumps

  • Pool pumps are classified into two types: single speed pumps and variable speed pumps.
  • Single speed pumps are the most common kind.
  • One flow rate is provided by a single speed pump, as indicated by its name.
  • It is sometimes referred to as a ″old pump″ since people are beginning to abandon this style of pump.
  1. When utilizing this pump, the pool owner often runs the pump for 6 to 12 hours each day, depending on the weather.
  2. Because it is single speed, you won’t have to bother about changing the speed while riding.
  3. Two-speed pumps are also available, which represent an improvement above single-speed pumps.
  4. With a two-speed pump, you have the option of switching between high and low speeds.
  1. Because of this, you may conserve energy by running the pump at a reduced pace.
  2. Alternatively, you may increase the pace of water circulation by running it at a fast rate.
  3. Meanwhile, a variable speed pump is a significant advancement in the field of pool pumping.
  4. The flow rate of this pump may be adjusted to your specifications.
  5. In spite of the fact that the pump does not require a lot of energy, it has the ability to move a large amount of water.

Purpose of pool pump

  • What exactly does a swimming pool pump do?
  • In theory, a pool pump circulates the water in the pool.
  • Bacteria, algae, and detritus may be found in stagnant water.
  • Surely, you do not want to be in the same water as those creatures.
  1. As a result, your swimming pool is kept clean, safe, and swimmable thanks to the pump.
  2. A pool pump operates by drawing water into the pool and pushing it out via a filter.
  3. The filter is the location where detritus, algae, bacteria, and other things are collected.
  4. The pump must be turned on at least once a day in order to keep the water clean and clear.
  1. This is referred to as the turnover rate.

Turnover rate

  • If you do not already know what your turnover rate is, you should find out as soon as possible.
  • The time required to pump and cycle all of the water in the pool is referred to as the turnover rate.
  • The size of the pool, the quality of the water, and the speed of the pump all influence the turnover rate.
  • In order to complete a cycle of water circulation in a standard-sized swimming pool, it takes around 7 to 8 hours.
  1. The pool pump should be running for 7 to 8 hours every day, according to this rule.
  2. Running the pump at a rate lower than the turnover rate does not produce the best results in terms of water quality and clarity.
  3. Running the pump at a higher rate than the turnover rate, on the other hand, is a waste of money.
  4. It is vital to note that if the pool is utilized by a large number of people or has a large number of particles, the water must be circulated at a faster rate or for a longer period of time.
  1. With increased sun exposure, the pool takes more time to heat up as well as cool down.
  2. If you want to know the precise turnover rate in a certain situation, you may calculate it using a mathematical formula.
  3. This is the formula that you may use to determine your eligibility: Pool volume divided by flow rate equals the number of hours required for one turnover.
  4. It is necessary to know the volume of your pool in order to use the calculation correctly.
  5. When comparing volumes, the volume is represented in gallons, and the flow rate is indicated in gallons per minute.
  6. The material of the pool has an impact on the turnover rate as well.

For example, a concrete pool often requires double the number of circulations as a fiberglass pool does.To maintain the water clean and safe, double the amount of electrical energy is necessary.

Right Time to Run Your Pump

  • Your question, ″How long should I leave my pool pump running?″ has been satisfactorily addressed.
  • In reality, it isn’t only a question of how long the pool pump should be turned on.
  • Further, it is also important to choose the most appropriate time to operate the pump.
  • Because eight hours is a long period of time for a gadget to be operational, you must actually optimize its operation by selecting the most appropriate time.
  1. When should a pool pump be turned on?

Non-peak hours

  • Avoid operating your pool pump during peak hours unless you want to be surprised by a hefty electrical bill at the last minute.
  • Peak hours are defined as a certain period of time during which individuals consume more power than normal.
  • This frequently results in increased strain on the power grid.
  • The cost of operating the pump during these hours may be higher than anticipated.
  1. Because peak hours vary greatly depending on where you are, you must be well familiar with them.
  2. Peak hours, for example, might occur in the afternoon when people begin to switch up their air conditioners to cool themselves.
  3. Alternatively, it may be in the evening when the majority of the lights are turned on.
  4. Contacting your power supplier can supply you with information on the actual peak hours in your area.
  1. As a result, you may create a timetable to ensure that the pool pump is running at the appropriate time.
  2. Interestingly, a pool timer may be a useful tool for ensuring that the pump is turned on and off at the appropriate times.

Day or night?

  • The fact that you are considering peak hours is not enough to establish when the best time to run the pool pump is.
  • On the surface, it appears that running the water during the day when people are using it will assist to keep the water clean.
  • However, there are a few more factors to examine before jumping to conclusions.
  • Chemicals must be put to your swimming pool on a regular basis in order to maintain it clean and sterilized.
  1. When you’re through adding the chemicals, it’s time to start the pump.
  2. This makes it possible for the chemicals to spread uniformly throughout the water body.
  3. If this is not done, the chemicals may remain in certain locations while others may not receive any chemicals at all.
  4. Some chemicals, such as pool shock, must be administered at night in order to be effective.
  1. You should avoid using a shock during the daytime since it will be damaged by the sun and so lose its potency.
  2. Remember to operate the pool pump for at least 8 hours at night when you want to add pool shock to your swimming pool.

Consecutive hours

  • For how long should I leave my pool pump running?
  • When you already know that a swimming pool has an average rotation rate of 8 hours, another question comes up.
  • Should the hours be counted as consecutive?
  • While some individuals believe that you do not have to run for 8 hours straight, others believe that you will get a greater outcome if you do.
  1. When you pump the pool, the water is drawn into the pool and then pushed out to the filter by the pump.
  2. When you pump for eight hours straight, there is a greater likelihood that the water will flow correctly than when you pump intermittently.
  3. Bacteria and algae have little chance of thriving in this environment since they will be trapped in the filter after only one cycle.

How to Reduce Pump Electricity Cost

Energy and money are expended when you run your pump for eight hours continuously. However, there are a few things you can do to lower your energy use as well as your utility costs. You will not be surprised by your power bills at the end of the month if you take these measures into consideration.

Do regular cleaning

  • In an ideal world, the pool pump would operate every day.
  • It contributes to the cleanliness and safety of your swimming pool.
  • Surprisingly, operating the pump every day might help you save money on your energy bills.
  • It takes more energy to circulate filthy water than it does to filter clean water, hence the pool pump uses less energy to filter unclean water.
  1. When you only operate the pump when you detect a significant change in pool clarity, you put more strain on the pump, making it work harder.
  2. It implies that more energy is being spent.

Know the required runtime

  • A swimming pool of standard size will typically run for eight hours on a single charge.
  • If you have a smaller pool, it will almost certainly take less running time.
  • Make sure you operate the pump at the appropriate time of day to save money on power.
  • Calculate the runtime of your pool using the method provided above to get an accurate estimate of how long it will last.
  1. Choosing a pool pump with a high horse power rating will help you to save time on the job.
  2. With this pump, you may reduce the runtime from 8 hours to 6 hours or even 4 hours.
  3. Cutting 2 hours off the runtime will result in a monthly savings of around $10.

Choose oversized pool pump

  • Not only does an oversized pool pump assure pool clarity, but it also helps to save costs.
  • A larger pump with lesser horse power lets the filter to perform more effectively, which results in cleaner water when you choose it oversize.
  • Meanwhile, decreased horse power has no negative impact on your wallet.
  • Consequently, the answer to your question ″how long should I operate my pool pump?″ is really dependent on the pool volume, although it is normally required to run the pool pump for 8 hours per day to maintain a clean, clear, and safe pool.
  1. Running your pool pump every day helps you save money on electricity since the pump is not working as hard to filter the water as it would otherwise.
  2. Furthermore, you must pay close attention to the appropriate time to operate the pump.

How Long To Run Saltwater Chlorine Generator (Chlorinator) & Pump?

  • The saltwater generator (also known as a salt cell, SWG, chlorine generator, or chlorinator) is responsible for ensuring that the pool water is safe to swim in at all times.
  • In order to do this, the chlorine generator and pool pump must run for an extended period of time in order to thoroughly clean the water.
  • So, how long should you leave the saltwater system running for optimal performance?
  • And what happens if you don’t let it run for a long enough period of time?
  1. The solutions to these and other questions will be provided in the following paragraphs.
  2. Let’s get started.

How Long To Run The Saltwater Generator For?

  • The chlorine generator should be left operating for an extended period of time in order to create the quantity of chlorine required to cleanse the pool on a regular basis.
  • This process takes between 8 and 12 hours on average, depending on the size of the pool, the kind of saltwater generator used, and the output level of the chlorine generator set.
  • Control panel for the saltwater chlorine generator.
  • The optimal output of a saltwater chlorine generator is between 50 and 70 percent of the total output.
  1. If the output of the saltwater system is set too low, you’ll have to operate the chlorine generator for a longer period of time to compensate.
  2. Later in this post, we’ll go a little more into the output of the chlorine generator.
  3. Maintaining close track of the chlorine levels in the pool prior to putting on the chlorine generator will allow you to set your chlorine generator’s power output for optimum performance and efficiency.
  4. The recommended chlorine concentration for saltwater pools is between 3 and 5 parts per million (ppm).
  1. If the chlorine level is greater than 5ppm, you’ll need to either reduce the number of hours the chlorine generator operates or lower the power level of the chlorine generator.
  2. If the chlorine concentration is less than 3ppm, you will need to operate the chlorine generator for a longer period of time or raise the power setting on the generator.
  3. Another option is to automate the functioning of the chlorine generator and pump by installing a pool timer.
  4. With the help of a timer, you may program the chlorinator (chlorine generator) to switch on and off at certain intervals.
  5. Some saltwater chlorine generator systems are also equipped with a timer that may be set manually.
  6. You should also be aware that the saltwater cell will only function if the pool pump is operating.

Unless water is being circulated around and through the salt cell, this device will not function properly.In reality, flow sensors are used by the vast majority of systems.It is not possible for the saltwater system to operate if the water flow is too low.The salt cell will not function or create chlorine when the pool pump is not operating and you attempt to activate the saltwater system without the pool pump functioning.There might, of course, be other factors contributing to your saltwater generator’s failure.We’ve written an article about it: There are 13 reasons why your saltwater generator isn’t working or isn’t producing chlorine.

How Long To Run a Saltwater Pool Pump For?

  • If you have a saltwater pool, it is recommended that you operate the pool pump for 8 to 12 hours every day on average.
  • There are two reasons why the pump in a saltwater pool must be turned on.
  • The first step is filtering the water.
  • In order for the pool water to be adequately filtered, the pump must complete at least one complete rotation of the water.
  1. The second reason is that the saltwater chlorine generator does not create enough chlorine to meet the demands of the environment.


  • It will be necessary to pump saltwater pool water through the pool’s filter, exactly as it would do with chlorine pool water.
  • At the very least, the water in the pool should be changed once a day.
  • The term ″turnover″ refers to the process of rotating all of the pool’s water through the filtration system at the same time.
  • You can figure out how long you’ll need to operate the pool pump by dividing the number of gallons per hour (gph) the pump produces by the volume of the pool (in gallons) in question.
  1. Consider the following scenario: a 3000 gallon per hour pool pump is required to run for 8 hours to complete the turnover of a 24,000 gallon pool.
  2. It’s also important to note that it’s recommended to change the water in the pool twice everyday.
  3. In this post, you will learn more about how to operate your pool pump and when to do so.

Chlorine Generation

  • The second reason why a saltwater pool pump must be running is in order for the chlorine generator (SWG) to function properly.
  • The chlorine generator (chlorinator) cannot manufacture chlorine if there is no water running through it during the process of production.
  • Most pools will require the saltwater generator to remain operational for 8-12 hours each day on average.
  • In order to adequately sterilize the pool’s water, it is necessary to create enough quantities of chlorine.
  1. Chlorine levels should be between 3-5 parts per million (ppm) for optimal sanitization.
  2. In the event that the chlorine generator or pool pump is not run for an adequate amount of time, what happens?
  3. Let’s have a look and see.

What Happens If The Chlorine Generator Is Not On Long Enough?

  • If you don’t operate the saltwater generator (also known as a chlorinator) for an extended period of time, there won’t be enough chlorine in the pool to properly clean the water.
  • As a result, the pool’s chlorine levels will be significantly reduced.
  • Furthermore, if the chlorine levels are too low, you will get murky or foggy water, as well as algae.
  • If this is the case, it might even indicate that your saltwater pool is hazardous to use.
  1. A list of the risks of saltwater pools may be found in this article: The Dangers of Swimming in Salt Water |
  2. Are they safe to use?
  3. Now, let’s take a step back and look into further detail about how saltwater pools function.
  4. When it comes to saltwater pools, a lot of individuals have erroneous information.
  1. They believe that salt is responsible for sanitizing the water.
  2. This is completely false.
  3. Saltwater pools, like ordinary chlorine pools, employ chlorine to clean the water in the same way as conventional chlorine pools do.
  4. There is just one difference between the two pools: in a conventional chlorine pool, the chlorine
