How Does A Sump Pump Work? Sump Pump Parts Diagram
To understand how a sump pump works, initially, we need to know what a sump pump is.A sump pump is a vital safety equipment that helps to evacuate water from the basement.It is a sort of automatic water removal system which may be used for removing floodwater or other forms of liquid.The sump pump works by producing suction in the drain pipe and then it drains the water via the sump pit.Next, we need to know about the pieces of a sump pit.
- Let’s have a look at its essential components.

Important Parts of a Sump Pump
The parts of a sump pit are:
Sump Pump Motor:
This is the heart of the sump pump.It creates electricity to run the complete machine.It has several power ratings, such as 1/4 horsepower, 1/2 horsepower, and 3/4 horsepower.These power ratings represent the amount of energy required to run the pump.This is measured in watts.
- It is also available in varying GPH (Gallons Per Hour) (Gallons Per Hour).
- GPH specifies how much water the pump can handle per hour.
- For example, if you have a sump pump rated at 1000 GPH, that indicates that it can handle up to 1000 gallons of water per hour.
It is one of the most crucial components of a sump pump. It links the motor with the sump pit. It should be composed of plastic material so that it can bear tremendous pressure. This is where the water enters the sump pit and drains water into the sewage line.
It is one of the most crucial components of a sump pump. It links the motor with the sump pit. It should be composed of plastic material so that it can bear tremendous pressure. This is where the water enters the sump pit and drains water into the sewage line.
A check valve prevents the backflow of water from the discharge pipe into the sump pit. If the check valve does not operate correctly, it may allow water to enter the sump pit even while the sump pump is working.
Battery Backup System:
If your sump pump malfunctions while you are gone, it could cause damage to your house. To prevent this, you can add a battery backup device. It offers a continuous power supply till the primary power source returns. There are models with a battery backup sump pump system to help you out during crises.

How Does a Sump Pump Work?
If you live in a property with a basement, having a sump pump installed is crucial.The sump pump water discharge system aids in keeping and managing the water in the basement.When there is heavy rain outside, the water rushes towards the lowest point in the region.In case of floods, the water level rises in the basement.Then, the water spills into the sump pit, causing damage to the foundation walls.
- In order to avoid this issue, a sump pump is needed.
- They are incredibly helpful equipment that help to keep the basement dry and safe.
- In order to use them successfully, you need to learn more about their operation.
- When water collects in the sump pit due of severe rainfall or any other reason, the sump pump comes into work.
- The float switch in the sump pump detects the presence of water in the subsurface area of the home.
- The sensor delivers an electric signal to the pump’s controller.
- This initiates the pump.
- The pump then starts functioning.
- The sump pump produces a vacuum inside the sump pit and sucks the water in using its suction hose.
- This is done using an electric motor.
Then, the water goes via the discharge pipe into the drain pipe.Once the pump stops pumping, the check valve closes automatically.This permits the water to move only in one way; it cannot return into the sump pit again.Then the pump will start again producing another cycle and the pump may wear out soon.
What Are Different Types Of Sump Pumps?
Sump pumps come in varied sizes and types based on the demands of each household. You can pick between a submersible pump or a pedestal kind.
Submersible Sump Pumps:
Submersible sump pumps are designed to be submerged in the earth and are powered by a submersible motor.Because they have a bigger capacity than a typical sump pump, these types of sump pumps can pump out a greater amount of water.These pumps are particularly well suited to homes with big basements and crawl areas.The majority of folks who utilize these are those who require high flow rates.
Pedestal Sump Pumps:
Pedestal-type sump pumps are typically utilized in small residences that do not require a large flood control system to function properly.They are also less expensive when compared to the ones designed for larger homes.These pumps are also suitable for use in attics since they do not require as much room as a submersible sump pump.You may purchase a sump pump in a variety of configurations, depending on your needs.However, before purchasing a sump pump model, make certain that you are well familiar with all of its features and characteristics!
How Long Does a Sump Pump Last?
A sump pump may endure for up to 10 years or more if it is properly maintained, but if it is not, it will not be able to work at peak performance.It is important to remember to replace the filter at least once every six months.If you observe any symptoms of blockage, you should physically clear away the sediment buildup.Some people like to clean the impeller wheel of debris on a regular basis, while others do not.By regularly cleaning the sump pump impeller, you can guarantee that all sections are free of debris and that no obstructions occur.
- You must conduct specific maintenance procedures on a regular basis in order for your sump pump to function properly.
- In order to learn more about the many elements that have an influence on your sump pump, we have created a full essay on the subject, which may be found below: Sump pump life is determined by a number of important factors.

How to calculate the sump pump capacity you need
- The fact that many homes have very active sump pits comes as no surprise when you consider how much rain falls on and around the average North American home throughout the year. Another group of people is lucky enough to reside in a place that drains well, and they only sometimes hear their sump pump running. Regardless of the position you find yourself in, it is critical that you have a sump pump in your basement that is strong enough to do the job. So, how can you figure out how much capacity you’ll need for your sump pump? Continue reading for some simple actions. Decide on a very wet, rainy day when the ground is saturated with water to conduct your water-level measurement on your sump pit’s water inlet. On a very wet or rainy day, turn on your sump pump and let it run until the water level reaches the shutdown level. While the pump is turned off, wait one minute, and then record how much the water increased during that minute period. Considering that normal sump pits measure roughly 18 inches in diameter (check yours to be sure), every inch of water contained within the pit is equivalent to approximately 1 gallon. Multiply the amount of inches that the water climbed in one minute by 60 to get an idea of how much water would flow into your pit during an hour of continuous raining in your area. To get the pumping capacity you require, multiply this number by a ″safety factor″ of 1.5 times the number you received. For example, if a sump pit collects 20 inches of water in one minute, or about 20 gallons, multiply 20 gallons by 60 minutes multiplied by 1.5 to obtain the required 1800 gallons per hour (GPH) capacity.
Learn all there is to know about your sump pit so that you can secure your basement to the best of your ability.Measure the water input into the pit several times, in the wettest circumstances, to ensure that you have a true understanding of the potential water volume you may be dealing with.Some homeowners, particularly those who have particularly active sump pits, elect to improve the safety factor of their systems.The simplest method to make that determination is to become familiar with your sump pit.Perform the first step (measure the sump water input) several times, especially if the ground is saturated due to excessively wet circumstances.
- Increasing the safety factor is possible; however, it is important to remember that if you get carried away and get a lot larger pump than you require, the pump will turn on and off very quickly, which might cause it to wear out prematurely.
- Finally, once you have determined the size you want and are looking for your pump, you will very certainly come across the phrase ″lift.″ This refers to the height to which the sump water must be pumped before the home may be left unattended.
- Consider the following example: many basements are 7 feet tall, plus an additional 2 feet into the sump pit, for a total of 9 feet of raise in height.
- Please keep in mind that a longer lift distance requires the pump to work harder, which results in a slower pumping rate.
Is Your Sump Pit Too Small?
The average pit measures 30 inches in depth and 18 to 24 inches in diameter.The conventional sump pit inserts offered at home improvement centers have a capacity of 26 gallons and a circumference of 18 inches.In many instances, the pit must be a minimum of 24 inches in depth and up to a maximum of 36 inches in depth.Some contractors, on the other hand, just utilize a standard 5-gallon bucket.A tiny pit fills with water extremely rapidly, requiring the sump pump to be turned on and off on a regular basis, reducing the life of the pump and the check valve it contains.
- Installing a backup pump purchased from a store in a tiny basin is impractical due to the possibility of its float being caught, resulting in basement flooding.
- If the sump pit is still too tiny or congested, you may need to drill through the bottom of the pail to move the main pump farther down, or you may need to cut the concrete and create a full-size sump pit to accommodate the increased volume.
- Many pumps, on the other hand, have turn-on levels of 6 to 8 inches and turn-off levels of 3 inches.
- Then, increasing the depth of the pit would have no effect on the pump’s short cycle time.
- It will take longer to fill a wider diameter pit, or you may install a pump with a switch that turns the pump on at a much higher level than the pit’s diameter.
- Short-cycling the sump pump causes its thermal overload protection to activate, resulting in the pump being turned off.
- As a result, the basement floods, despite the fact that the sump pump is not broken and will function normally once it cools down.
- You won’t have to worry about the backup pumps failing!
- They are elevated significantly above the pit or above the typical water table.
- They simply require a little amount of room within the pit to accommodate the suction pipe and a float.
Additionally, Hi & Dry battery pumps are equipped with a slim-line vertical switch to reduce the possibility of tangling.
What Is Water inflow into My Sump Pit?
If you are more of an engineer than a layperson, you may estimate the approximate capacity of the backup sump pump that will be required.Determine the minimum pump capacity required by multiplying the amount of water in the sump basin by the volume of the sump basin.On a wet day, lower the water level in the sump with a yardstick until it is at its lowest point.Then, find out how many inches the water rises in one minute by looking at the graph.Example: An 18-inch sump with a water rise rate of 6 inches per minute corresponds to a flow rate of 420 US gallons per minute.
- Apart from the task of emptying the sump pit, the pump must also deal with the water that is rushing into the pit while it is pumping.
- Increase the required pump capacity by 20 percent to 50 percent to account for a safety buffer.
- Then you must determine the required lift, which is the height to which the pump must raise the water from the bottom of the sump pit.
- A pump can remove far more water at a 5-foot ″head pressure″ (lift) than it can if it had to pump from a height of 10 feet.
- For each elbow, add an additional foot to the length.
- But how can this little sump pump serve as a backup to my massive primary sump pump?
- The primary pump does not pump constantly; instead, it empties the pit and waits for the sump to fill back up.
- Consider the following scenario: your pump has a capacity of 2,400 gph and empties the pit in 10 seconds once per minute.
- After that, it only pumps for 600 seconds (60 cycles x 10 seconds), or 10 minutes each hour, and transports around 400 gallons per minute (10/60 x 2,400).
- However, the backup pump will take longer to empty the sump (say, 20 seconds), and it will then have to wait for the water level to increase again before it can start working again.
Sump Pump Flow & Discharge Rates – 2022 Pump Table
In order to avoid basement flooding, it is necessary to utilize the proper sump pump size.Horse power is commonly advertised on sump pumps, however this can be confusing.What you really need to know is the flow (discharge) rate of your sump pump in order to obtain the correct pump!I’m not sure how much water is flowing via your sump pump.Few individuals are familiar with their pump’s discharge rate – or even how to calculate it!
- All you need to compute flow rate is a tape measure, a timer, and a pail of water, which are all readily available.
- Are you ready to begin measuring the flow rate of your sump pump?
- Most instruction manuals provide flow rate tables; however, if you have misplaced your paperwork, follow these step-by-step instructions.
- Begin by calculating the quantity of water that enters the hole every minute of the day.
- Second, determine the height to which you must raise the water (aka the head height).
- Once you have all of the statistics, it is simple to determine the appropriate size pump — keep in mind that higher flow rates imply greater horse power.
How to Increase Flow Rate
- It’s possible that your pump is straining to clear the water from the pit
- if this is the case, you may need to raise the flow rate. Although your pump may have claimed a maximum flow rate, this does not always imply that it is now functioning at top efficiency. Reduce the amount of lift required. The higher the pressure at which your pump must push water, the more effort it must do and the less water it can remove. Drainage pipes should be installed closer to the water source to reduce evaporation.
- Install a filter on your system.
- Some of the basins become clogged with dirt and other material. Inspect and clean the filter on your pump on a regular basis to ensure it is working properly.
- Purchase a bigger pump.
- Some pumps are too tiny for the pit in which they are installed. It is possible that your home (or crawl space) will require a pump with higher horsepower as a result of changes in the water table, new construction, or increased rainfall.
You’d want to know how much capacity your pump has. Make use of this formula. – Inches of water multiplied by 60 minutes multiplied by 1.5 = Gallons per Hour
|Pit Diameter||Gallons of Water|

How Much Water Can A Sump Pump Move
1 gallon of city water pumps 2 gallons of water out of your sump pumping system (See exact water usage figures for our model MG22 or model MG36). When the water-powered sump pump is turned on, 1 gallon of city water will run through the pump, drawing out 2 gallons from the sump and discharging a total of 3 gallons outside the residence, depending on the size of the sump.
How many gallons per minute does a sump pump pump?
The average homeowner’s sump pump has a horsepower rating of between 1/3 and 1/2. The typical discharge rate is between 2500 and 3200 gallons per hour (gph), or 42 to 53 gallons per minute (in metric units) (gpm).
How far can a sump pump push water horizontally?
Typically, 1/3 HP pumps can handle vertical elevations of 7′ – 10′ from the sump pit if they are equipped with one 90-degree elbow and a horizontal pipe run of between 3′ and 25′.
Can a sump pump overflow?
Sump pump overflow is caused most commonly by an electrical failure, which is ranked first among the causes. As a result of the storm, if you lose electricity, your sump pump will also lose power, which might result in tragedy. Having a battery backup system in place might help you avoid this situation. This guarantees that your sump pump is operational when you require it the most.
What water does a sump pump move?
What is the operation of a sump pump? Sump pumps are responsible for transporting water from your basement to the outside of your property. When a sump is formed naturally, it’s normally in the form of an opening dug into the main surface of your basement floor. The sump pump is housed in this pit, which is referred to as a basin.
Can a sump pump be too powerful?
If a pump is either too little or too strong, that is not what you want. If the pump is too tiny, it will not be able to keep up with the amount of water that is being pumped into the basin. A ″short cycle″ is caused when the pump is very strong. Because of this, the pump will cycle often, which might result in premature pump failure.
Should my sump pit have water in it?
First and foremost, it is totally typical for a sump pump pit to have some water in it, if not all of the time. In most cases, if there is consistently too much water, there is most likely an issue, especially if you never hear your pump start up.
How high can a 1 hp pump push water?
A one-line or single-line jet pump has a maximum lift capacity of approximately 7.5 meters or 25 feet of water. A two-line jet pump with the same horsepower will have no issue lifting water up to 60 feet in a single pass.
How much does it cost to replace a sump pump?
The Price of a Sump Pump Installing a sump pump typically costs between $638 and $1,979, with an average cost of $1,259 in most cases.Sump pumps on pedestals range in price from $60 to $170, while submersible pumps range from $100 to $400.For the installation, you should expect to pay between $45 and $200 per hour.The installation of submersible sump pumps takes longer than the installation of pedestal ones.
Is 1 2 HP sump pump enough?
It is unlikely that the 1/2 hp pump would create any issues, however in cases where the water flow into the sump is quite slow, utilizing the bigger pump might be counterproductive. While a 1/2 horsepower pump will keep up with the flow of water in most instances, a 1/3 horsepower pump may not be able to keep up with the flow in other scenarios.
How do you keep a sump from overflowing?
There shouldn’t be any issues with the 1/2 hp pump; but, in cases in which water flow into the sump is quite slow, utilizing the bigger pump would provide little benefit. While a 1/2 horsepower pump will keep up with the flow of water in most instances, a 1/3 horsepower pump may not be able to keep up with it in other scenarios.
Will basement flood if sump pump fails?
If your sump pump malfunctions after a heavy rainstorm, your basement may flood, resulting in serious water damage to your house as well as a major mess on your hands. When there is a power outage, the most typical reason of sump pump failure is.
Will a basement flood without a sump pump?
If your home does not have a functioning sump pump, the extra water from a severe storm will begin to gather at the lowest point in the structure. The foundation, crawlspace, or basement may serve as the meeting place. Whatever the location of the water’s final resting place, it will begin to bend wood, create rot, and promote mold development.
Why does my sump pump stink?
Dryness Is the Root of The Smell of the Sump Pump It is possible that the water in your home’s sump pump pit will evaporate throughout the course of the year’s dry spell. As the water from the pit evaporates, it releases odorous gases into the air, which you can smell in your house. The remedy to this problem is a simple do-it-yourself project.
Does shower water go to sump pump?
Sump pits are typically filled with water from many sources such as your washing machine, shower, dishes, dishwasher, and sometimes even the toilet. No matter what sort of sump pump you have installed in your home, it will not survive indefinitely.
Why does my sump pump hole keep filling up?
The sump pump and/or liner are either too tiny or too large for the purpose — If the sump pump is just not large enough to accomplish the job, it will run continually to keep up (see1 above). Other times the pump is powerful enough, but the sump pit is too tiny, leading it to fill up too quickly and forcing the sump pump to run continuously at high speed.
Is it normal for a sump pump to run every 15 minutes?
In the majority of circumstances, it is completely common for a sump pump to operate continuously after heavy rain, sometimes for as long as two or three days. So it’s normal for your sump pump to be working overtime during heavy rains, but if it continues to run for an unusually extended period of time after the rains have ceased, you may have a serious problem on your hands.
How many years does a sump pump last?
On average, how long does a sump pump last in a home? Your sump pump, like all other appliances and pieces of equipment in your home, will not endure indefinitely. Because sump pumps have a lifespan of around 10 years, you may not discover that yours has failed until it ceases to function.
Is it normal for sump pump to run every 30 seconds?
Something may be amiss if your sump pump is operating every 30 seconds, which might suggest a problem.It is possible that there is a flaw in your basement foundation that is causing water to be trapped and the pump to run every 30 seconds, forcing the pump to run constantly.The fact that your sump pump is cycling on and off every 30 seconds might possibly be the result of a damaged subterranean water main.
Where is the water in my sump pump coming from?
There are several ways in which water can enter a sump pump: it can enter by funneling into the pump through the designated perimeter drains in a basement’s waterproofing system, or it can enter by gravity due to groundwater or rainfall if the basement happens to be below the water table level, if the basement is below the water table level.
Where does the water in my sump pit come from?
Water enters the sump pit by drains or by way of natural water migration through the earth, depending on the situation. The sump pump’s function is to pump the water out of the pit and away from the structure, ensuring that the basement or crawlspace is kept dry and protected. Sump pumps are becoming increasingly frequent in new built homes.
Where should I run my sump pump discharge?
Drainage from your sump pump should be directed away from your home. Do not allow it to overflow onto roads, sidewalks, or other paved surfaces, such as concrete. The discharge must be clear, pure water, such as groundwater or domestic air conditioner condensate, in order to comply with the regulations.
How many gallons per hour does a sump pump pump?
A sump pit can hold roughly 20 gallons of water in one minute, or 20 inches of water.Calculate the required Gallons per Hour (GPH) capacity by multiplying 20 gallons by 60 minutes by 1.5.All of this is covered in further detail here.To put it another way, how many gallons of water does a sump pump move?When the sump pump is driven by city water, one gallon of water is used to pump two gallons out of the pit, and then all three gallons are expelled from the home.
- When running at 1,000 GPH, the system will utilize 5,000 gallons of water to prevent 10,000 gallons of water from flooding your basement, based on the 1 to 2 ratio.
- As a result, the question is whether a sump pump can be completely submerged.
- The float, which is located on the side of the pedestal, is responsible for activating it.
- Because the engine on the pedestal is not entirely sealed, it cannot be totally submerged.
- It has the potential to short out the motor as well as pose a shock hazard in standing water.
- In order to function properly, sump pumps must be immersed in water.
- Is it necessary for me to have two sump pumps in this case?
- In the event that your basement floods, what kind of damage would it cause to your home?
- As a result, one possible solution to this potential problem is to install two sump pumps in the same sump pit basin, rather than one.
- A second sump pump can assist to lessen the possibility of one of them failing or not being large enough to manage a heavy downpour during a storm.
Do I require a sump pump with a horsepower rating of 1/3 or 1/2?If you live in a typical-sized home with a higher-than-average water table, you will almost certainly require a 1/2 horsepower sump pump.These pumps will typically pump 35 percent to 40 percent more water than their 1/3 HP counterparts, and they can also tolerate larger vertical lifts for the water being pumped through your discharge pipe than their 1/3 HP counterparts.
Sizing Up a Sump Pump
Duane Friend, University of Illinois Extension, contributed to this article.
The right sump pump should be big enough to handle the expected volume of water and strong enough to get it outside the structure.
As the beating heart of most drainage systems, sump pumps must be correctly matched to soil conditions, pit size, and other criteria in order to minimize short-cycling while yet providing adequate capacity for peak occurrences.When it comes to the continuous struggle for dry basements, sump pumps play an important role.It is usual for a pump to need to be updated every few years.However, if the pump is properly sized, it will last far longer, and the homeowner will know that it is the proper pump for the job.When choosing the size of a sump pump, you must consider two factors: system capacity (the quantity of water that will be circulated) and total dynamic head (the amount of water that will be pushed) (where it will be pumped).
Determine System Capacity
The first step is to establish the capacity of the system.It is critical that your pump is capable of drawing water out of the basin (also known as the ″sump pit″) at a higher rate than water flows into it.As a result, the first item that has to be observed is the volume of water that drains into the basin during a period of high flow.Buildings that are already there: During a severe downpour, insert a ruler into the basin and record the number of inches of water that flows into the basin in sixty seconds.Preparing for a very wet, rainy day and then running your sump pump until the water recedes to the shutdown level is the quickest and most straightforward method of doing this test.
- Wait for one minute with the pump turned off, and then record how much the water rose during that one minute period.
- Use the following rules of thumb to figure out how many gallons flow into the basin every minute (the system capacity): One gallon of water is equivalent to one inch of water in a basin with a diameter of 18 inches.
- When measured in the larger 24-inch-diameter basin, one inch of water is approximately equal to two gallons of water.
- If it is discovered that more than 30 gallons of rainwater per minute flow into the basin, the installer might be better off using a basin with a 24-inch diameter.
- Always remember that the water level should never be allowed to climb over the bottom of the sump’s inflow pipe, regardless of how high the water level appears to be (coming in from the foundation drain tile.) For example, you measure the flow of water into your sump pump basin using a ruler and discover that 18 inches of water flow into the basin every 60 seconds.
- Because you have a basin with a smaller diameter (18 inches), each inch is equal to one gallon.
- As a result, the System Capacity of your system is 18 gallons per minute.
- Construction of a new building: But what if you’re moving into a new home where a security system hasn’t been installed yet?
- If such is the case, the following are some general guidelines: Plan on your system having a capacity of 14 gallons per minute for every 1,000 square feet of your home if you have sandy soil.
- In clay soil, a system capacity of 8 gallons per minute should be planned for every 1,000 square feet of living space.
Example: 2,000 square feet is the size of the building footprint shown in the blueprints.Considering that the house is built on sandy soil, the sump pump system should have a maximum flow rate of 28 gallons per minute.
Determine Total Dynamic Head
Total Dynamic Head is equal to the sum of the Static Head (also known as ″vertical lift″) and the Friction Head.It is the vertical height that the water climbs from the pump intake to the discharge pipe’s end that is referred to as static head (or the highest point in the discharge line).To calculate Static Head, start measuring at the place where the water enters the sump pump and work your way up.Then take a vertical measurement up to the point where the pipe becomes horizontal.The Static Head is the weight of the water that the pump must lift, and it is measured in vertical feet (vertical feet) (see Figure 1).
- Example: Assume that the distance between the sump pump and the point at which the discharge pipe becomes horizontal is 13 feet in height.
- The Static Head is seen here.
- The process of determining Friction Head is more complicated than the process of measuring Static Head.
- In order to calculate Friction Head, the following formula must be used: ″the equivalent length of pipe″ plus the actual length of pipe multiplied by the ″friction loss″ divided by 100.
Here’s a step-by-step method:
Step 1: Calculate the ″Equivalent Length of Pipe″: The ″equivalent length of pipe″ is calculated by the number of pipe fittings present in the discharge line, as well as the diameter of the discharge line.Table 1 displays the ″equivalent length of pipe″ for various fittings based on the size of the pipe being used in the fitting.Consider the following scenario: you’re utilizing 114-inch pipe, three 90-degree elbows, and one check valve.A check valve adds 11.5 feet of comparable pipe, whereas three elbows add 10.5 feet, according to Table 1.With these fittings, the ″equivalent length of pipe″ is increased to 22 feet.
- The second step is to determine the actual pipe length.
- It is the total length of pipe that runs horizontally out of the home that is measured in feet.
- You should be able to see where the pipe exits the house from the inside of your home.
- Consider the following scenario: the discharge pipe is 100 feet in length, as shown.
- Step 3: Calculate Friction Loss: Friction loss is the amount of time that water flowing through a pipe is slowed by friction.
- Table 2 illustrates the amount of friction loss that happens for different pipe diameters based on how many gallons of water per minute are passed through the pipe.
- When working with Table 2, enter your System Capacity number as the ″gallons per minute″ value.
- For example, if you have a 114-inch pipe with a flow rate of 18 gallons per minute, you will have a friction loss of 5.25 per 100 feet of pipe.
- Step 4: Bring everything together: To calculate Friction Head, multiply the actual length of the discharge pipe by the ″equivalent length of pipe″ resulting from the fittings’ length.
- Then increase the result by the friction loss (as determined in step 3) and divide the result by 100.
Using the above example, we may get 122 feet by adding the actual length of discharge pipe (100 feet) and the equal length of pipe from fittings (22 feet).This is then multiplied by the friction loss per 100 feet of pipe (5.25), which is then divided by 100 to get 6.40.122 x 5.25=640.5 640.5 divided by 100 = 6.40 The Friction Head is located at 6.40.Having obtained the Static Head and Friction Head, we can simply put the two figures together to obtain the Total Dynamic Head.Example: To calculate the Total Dynamic Head, multiply the Static Head (13 feet) by the Friction Head (6.40) and divide the result by two.
Increase the length by one foot for a total of 20 feet.
Selecting the Pump
You now have an understanding of the System Capacity (18 gallons per minute) and the Total Dynamic Head (TDH) (20 feet).So now you’re ready to make a decision on a pump.The majority of sump pumps feature charts or curves that illustrate how many gallons per minute they can pump for various lengths of pipe or pipe lengths (See Figure 2).You’ve previously calculated the number of gallons per minute that must be pushed out of the tank.To ensure that the pump can handle the amount of gallons per minute specified in these charts, consult them.
- If a pump is either too little or too strong, that is not what you want.
- If the pump is too tiny, it will not be able to keep up with the amount of water that is being pumped into the basin.
- A ″short cycle″ is caused when the pump is very strong.
- Because of this, the pump will cycle often, which might result in premature pump failure.
- If the total dynamic head is 20 feet, for example, you have just one option among the four pumps indicated in Figure 2.
- Pump 1 will be the only one capable of handling 18 gallons per minute.
- The other three pumps are only capable of pumping a maximum of 12 gallons per minute.
- It should be noted that in this particular scenario, using a bigger diameter pipe may result in a lower friction head, allowing you to utilize a different pump (Pump 2 on the chart).
Maintaining the Pump
Periodic maintenance is required for sump pumps.You may ensure that the system remains in peak operating condition by following these steps: Check the operation of the float to ensure that it is not hindered in its up-and-down movement.When the pump is running, check the exterior end of the discharge line to make sure it is releasing water and not just air.A number of factors can contribute to water not being discharged, including a jammed check valve, an impeller that has become loose on its shaft, or a clogged water line.Even if the sump pump has not been required to operate for several months, fill the sump pump basin with enough water to activate the float switch at the start of the rainy season.
- This manner, you can be certain that the pump is still functioning correctly.
Basin Diameter: The majority of homes have a basin or sump pit with an 18-inch diameter.The size of the basin has an impact on how long the pump operates and how long it takes to fill the basin.If your present basin is inadequate and fills up too rapidly between pumping cycles, it may be necessary to add a larger basin to meet the increased flow rate.Another solution that may be less expensive is to install an adjustable float switch, which permits the water level to increase to a higher level before allowing the pump to turn on.Most pumps rely on the presence of water in the pump at all times in order to lubricate and cool the pump seals and other components.
- As a result, make certain that the float switch is in the proper position to prevent the pump from running dry.
- Pumps of the pedestal type include floats that may be set to a variety of lengths in order to operate.
- Check valve (also known as a check valve): Select a swing-type check valve with a bore that is the same size as the outlet pipe.
- It should be installed directly above the sump pump.
- Between pump cycles, the check valve prevents the water in the discharge line from flowing back into the basin.
- Electrical Circuit: The sump pump must be equipped with its own dedicated motor control circuit and breaker, as well as its own dedicated motor control circuit and breaker.
- When establishing electrical circuits, be sure to adhere to all applicable municipal electrical laws and ordinances as well as safety precautions.

When Choosing the Right Sump Pump for Your Home, Consider This
- When it comes to sump pumps, more isn’t necessarily better in this case. Installing a 12-horsepower special to blow water out of your basement as rapidly as possible is not a cost-effective solution in this situation. Why? It causes the pump to spin more quickly than is necessary, reducing its life expectancy and necessitating the need for replacement. When it comes to selecting the best sump pump for your home, the first step is to look at the data plate on your current or prior sump pump. A data plate is located on the outside of every sump pump. When the sump pump is turned on, it displays the model and HP information. When replacing an old pump with a new one, it’s preferable to keep the same horsepower, but keep the following factors in mind: – Sump pumps are not all made equal, as you may have noticed. The quality of the output varies from maker to manufacturer. The amount of Gallons Per Minute (GPM) provided varies depending on the kind of pump and model. – Vertical float switches and electronic float switches are effective in sump pits of various sizes. – When employing a tether float switch, your sump pit’s diameter must be at least 14 inches in order to function properly. Float switches that are used in sump pits with diameters less than 14 inches may ″stick″ if the pit is too tiny. Tether float switches can become tangled in debris in your sump pit, which can cause them to become inoperable. – Sump pumps are available in a variety of horsepower configurations. A sump pump must have a certain amount of horsepower to accommodate the usual water table in your property. – What processes does the water that is being discharged go through before it is pumped out of the house? The vertical lift off the sump pump
- the angle of the elbow in the pipe
- and the length of the horizontal pipe.
Determining the Right Amount of Horsepower Needed From Your Sump Pump
Do you require more horsepower than your present sump pump is capable of producing? if the vertical lift off of the sump pump is great, if the horizontal pipe extends between 30 to 150 feet, if there is an interruption in water flow, you should do so A larger horsepower will result in a higher pumping capacity and a higher GPM output, respectively.
1/3 HP Submersible Sump Pumps
The ordinary home with a typical water table requires no more than a 1/3 HP sump pump to function properly. It is the most popular sump pump size and is capable of handling most water tables with ease. A 1/3 horsepower sump pump is capable of handling a vertical lift of 7 to 10 feet from the sump pump, a 90-degree elbow, and a horizontal pipe spanning between 3 and 25 feet in diameter.
1/2 HP Submersible Sump Pumps
A 1/2 horsepower sump pump will most likely be required for the ordinary home with a higher than normal water table.This sized sump pump can pump around 35 to 40% more water than 1/3 HP sump pumps can pump.The discharge of water from a 1/3 HP pump is capable of handling a larger vertical lift when the water level is higher than usual.A 1/2 horsepower sump pump is capable of handling a vertical lift of 7 to 10 feet from the sump pump, a 90-degree elbow, and a horizontal pipe spanning between 3 and 25 feet in diameter.
3/4 HP Submersible Sump Pumps
- A 3/4 horsepower sump pump has a pumping capability that is 20 to 25 percent greater than that of a 1/2 horsepower sump pump. It is possible to use this size pump to manage a high vertical lift of 20 to 30 feet and/or horizontal pipe runs ranging from 150 to 250 feet in length. When should you think about installing a 3/4 horsepower sump pump in your home? you live in a flood plain or low-lying area
- the water table in your area is elevated and hence vulnerable to flooding
- your basement is very deep
- the water is released through more than 10 feet of horizontal pipe
- you are utilizing the pump for outdoor pumping

Should My Sump Pump Pit Always Have Water Inside It?
14th of June, 2021 As specialists in sump pump installation and maintenance, we regularly receive the following phone call regarding sump pumps: Is there supposed to be water in the pit?In the case of a sump pump that has recently been installed or a sump pump that has recently been purchased, having this equipment may be a completely new experience for you.But don’t be alarmed.You will learn all you need to know about your sump pump pit and how to tell if your sump pump is having problems in the sections below.
My sump pump pit always has water in it. Is that bad?
It is composed of two parts: the pump itself, and the pit in which it is designed to function, or sump pump pit.If there is usually some water in a sump pump pit, it is totally typical and should not be considered abnormal.It is possible that this water is the product of rain, snowmelt, or seepage from the earth.However, when the water level in your sump pump reaches to a particular level, the float switch on your sump pump should activate.This will cause the pump to switch on and begin to function properly.
My sump pump pit frequently goes dry. Is that bad?
Both yes and no.The sump pump pit should not be left dry on a regular basis, since this is not desirable.A dry sump pump pit can cause the plastic and rubber components of the pump to wear out prematurely, resulting in increased costs.As a result, you’ll need to repair or replace the sump pump considerably sooner than you would have otherwise.On a good side, it’s possible that you don’t have the flooding problem that you thought you did after reading the report.
- It is possible that the seepage is caused by a pipe or drainage problem, which a plumber may inspect and resolve for you.
What if my sump pump pit is always full of water?
Just as you don’t want a sump pump pit that is continually dry, you also don’t want a sump pump pit that is constantly full of water.This might be an indication that the water table in the area where the pump is located is excessively high.Additionally, there might be an issue with the sump pump itself, such as a clogged or frozen discharge line, which is preventing water from draining.Problems with your home’s plumbing might also result in a sump pump pit that is continually overflowing with liquid.For example, a clogged sewage line, a ruptured water line, or a malfunctioning sprinkler system can all lead to water seeping into the ground near your home’s foundation.

How to Size a Sump Pump
- The Dimensions of a Sump Pump The chance of having items damaged when it rains or storms increases, and having a damp basement increases the likelihood of mildew, germs, and disease spreading throughout your home as a result of the moisture. According to further estimates, approximately 38 percent of all moist basements are home to mold and mildew issues that continue to worsen. If you purchase a sump pump, be certain that it is the appropriate size! How to Calculate the Size of a Sump Pump The size of your sump pump is determined by a variety of factors. The following calculations can be used to determine the proper size of a sump pump to purchase when deciding the size of a sump pump to purchase: Capacity. The horsepower of the pump and the capacity of the pump. In terms of overall power, the pump is more essential than the entire volume of water it can pump. It must remove water from the sump pit at a higher rate than new water flows into the sump pit to be effective. In addition to having more pumping capacity, higher horsepower pumps can remove a greater volume of water more quickly. During high water flow days, you must take measurements of the amount of water that drains into the sump pit. If you already have a sump pit, insert a measuring tape into the pit and record how many inches of water fill the pit in 60 seconds using the tape measure. Make sure to start when the pump basin (pit) is completely dry and to do it on a day when there is a lot of rain. It is also important that the water level never rises any higher than the bottom of the sump pit’s inflow pipe. In one minute, a standard sump pit will rise 20 inches, or approximately 20 gallons. One gallon is equal to an 18-inch-diameter hole filled with one inch of water. When filled with one inch of water, a 24-inch pit holds two gallons, and 24-inch pits can often hold 30 gallons of water. If you are building a new sump pump, you should anticipate that every 1,000 square feet of your home will require a capacity of 14 gallons per minute if your home is built on sandy soil. If you are building on clay, you should anticipate that every 1,000 square feet of a house will require a capacity of 8 gallons per minute. Then divide the number of inches the water climbed by 60 to get the total height of the water. This calculation will provide you with the amount of gallons consumed in one hour. Additionally, double this figure by 1.5 to give you with a safety net in the case of a very severe storm or thunderstorm. Your final value represents the amount of pump capacity you require. Pro-tips include the following: (1) Using a bigger pump than you require causes the pump to cycle on and off more frequently, causing the pump and check-valve to wear out more quickly. (2) Repeat this process in different weather conditions and on different days to confirm that your figures accurately reflect your requirements.
- Horsepower. The normal sump pump has a horsepower of.33, however sump pumps are also available in lesser horsepowers of.25 and greater horsepowers of.33. 5 and.75 horsepower models are available. In one hour, most.5-horsepower pumps can remove up to 3,000 gallons of water. Consider the above-calculated capacity requirements when selecting a pump that is the appropriate size to handle the volume of water that will be pumped into the basin. Factors that complicate the situation Width. Sump pits that are bigger or broader in diameter may fill more slowly, affecting the conclusion of the capacity calculation. Prepare for the possibility of deep or wide sump pits by making additional provisions. A typical sump pit measures 30 inches in depth and 18 to 24 inches in width.
- Below the level of the water table Basements that are below the water table, against a sloping yard, or that are prone to flooding may require a larger sump pump than basements that just experience the odd basement flood.
- Lifting the basement floor (height). Water intrusion into your home should be avoided at all costs, and any substantial vertical rises should be taken into consideration. In sump pump terminology, a vertical lift is the distance that the sump pump must move water vertically in order to raise existing water above the water level. A sump pump that is underpowered can be drained by falling from great heights. Depending on whether you have a sloping yard or need to pump water up a vertical lift (height), you may want a sump pump with a higher horsepower to overcome gravity. In these situations, the pump must work harder in order to lower its pump rate, thus get the pump that is one size larger than your calculated requirement.
Examine the water flow requirements and the maximum number of gallons per hour that a pump can handle when selecting a pump for your application.Most of the time, the sump pump box will have these parameters printed on the exterior of the box.Will my homeowner’s insurance cover the cost of sump pump repair?When it comes to your house insurance coverage, you may acquire an equipment breakdown endorsement as an add-on.Maintenance and mechanical problems are covered under this endorsement.

The amount of water that water-powered sump pumps use is less than you think.
When people discover about water-powered backup sump pumps, one of the first questions they ask is, ″How much water does it use?″ This is a fairly typical inquiry.This is an excellent question because, unlike other emergency backup pumps that rely on batteries to create their pumping power, water-powered backup pumps rely on the water pressure in your home to generate their pumping power.It does not require the use of energy or batteries, but it does require the usage of some water.Even though we are unable to comment on other water-powered sump pumps, we can provide you with an estimate of how much water our Water CommanderTM water-powered backup sump pump consumes.
1 Gallon of City Water Pumps 2 Gallons From Your Sump
It takes roughly 1 gallon of municipal water to pump 2 gallons of water from your sump pit, according to Water CommanderTM.When you have higher-end pressure (70 PSI or greater), this ratio increases marginally.In our model MG22 and model MG36, you can see the precise amount of water they use.When the water-powered sump pump is turned on, 1 gallon of city water will run through the pump, drawing out 2 gallons from the sump and discharging a total of 3 gallons outside the residence, depending on the size of the sump.
How Much Water Does It Use In One Hour?
While Water Commander will pump as frequently as necessary during a storm, a typical frequency during a hard storm might be one cycle every minute.The pump would consume 180 gallons of city water in one hour if it used 3 gallons of city water to remove 6 gallons of sump water every cycle, which would use 3 gallons of city water per cycle.(3 city gallons per minute multiplied by 60 minutes).
Do Water-Powered Sump Pumps Use Too Much Water?
You might be thinking if this is an excessive amount of water. Let’s take a look at some statistics to put things into perspective. In comparison to how much water the average person uses throughout the course of an average day, you’ll be astonished to hear that it’s small.
Typical Annual Water Usage: Equal to Running Sprinkler for One Hour
According to the Energy Information Administration, the average electrical power consumer in the United States suffered an average of 6 hours of power disruption for the year 2018.The consumption of 1,080 gallons of city water per year by your water-powered sump pump during these outages (heavy storm scenario) would result in the pump using a total of 1,080 gallons of city water per year (6 hours per year x 180 city gallons per hour = 1,080 gallons per year).The whole annual water consumption of a sump pump driven by water is 1,080 gallons, which is comparable to the total annual water consumption of a sprinkler powered by water, which is 1,020 gallons.A typical year’s worth of use for a water-powered backup sump pump is the equivalent of just one hour of watering your grass!
Severe Scenario: Equal to Running Sprinkler for Four Hours
As an example, consider the worst-case scenario: severe rain for 24 hours while the electricity is off.The sump pump is set to operate once every minute for the whole 24 hours.We can assume that the pace of 180 gallons per hour is maintained throughout the day, but that would only amount to 4,320 gallons throughout the course of the day.Once again, using the sprinkler as an example, this is about similar to operating a regular sprinkler for 4 hours each week for a week.Always remember that water-powered sump pumps aren’t just for keeping the grass looking nice; they’re also for preventing homeowners from suffering thousands of dollars in bills as a result of a flooded basement.
Water-Powered Sump Pumps Use a Relatively Low Amount of Water and Only in Emergencies
In practice, water-powered sump pumps are only used as a last resort.The majority of the time, your primary electric sump pump is responsible for keeping your sump free of water.During a power outage or a breakdown of the primary sump pump, on the other hand, your backup pump becomes critical until the power is restored.Battery backup pumps frequently fail as a result of a dead battery or their limited operating time capacity.Sump pumps driven by water, on the other hand, will never run out of power.
- Using a couple thousand gallons of water once a year (equal to running your sprinkler for several hours) to save your basement is a tiny price to pay for the long-term preservation of your home.
- An estimated $3,000 to $10,000 might be spent to repair a flooded basement, according to one source.
