How Long Can A Water Pump Run Continuously

How Long Can A Well Pump Run Continuously

Every home is equipped with a well pump that ensures that you have access to pure water at all times. A water lifter is used in every watering system, and this is true for every type of irrigation system. You’ll find them a lot in agricultural fields, where they’re used to provide irrigation for the crops. When water is released from the subsurface reservoir, it employs centrifugal force to propel it directly onto the land or into your houses. However, the length of time a well pump can run continuously is controversial and relies on a variety of conditions.

Depending On The Type Of Well Pump

Pumps with a centrifugal force When it comes to operating your reservoir water pushers nonstop, one of the most important elements to consider is the sort of water pusher you have. Type comes in a variety of sizes and powers, each of which contributes to how long it can hang on for. They are normally available in three distinct configurations.

1. Centrifugal Pumps

These sorts of pumps are utilized for shallow water reservoirs and have less power than the other types of pumps available. The depth of the wells is normally approximately 25 feet or lower. Because these water lifters may be used in shallower wells that hold less water, the water will drain out more quickly as a result. As a result, the runtime is significantly shorter than that of competitors.

2. Submersible Pumps

Pumps that are submersible Submersible pumps are the most often used industrial and commercial pumps because of their low cost and high efficiency. These pipelines have the ability to draw water from as deep as 25 feet underground. As a result, it may be utilized in both shallow and deep reservoirs. As a result, it implies that it has more suction power. Additionally, because of its appropriateness for deep wells, it is feasible to keep and supply more water, resulting in a longer period of uninterrupted water supply.

3. Jet Pumps

These jet pumps are the most powerful in the business, and they are available in two different configurations. The less powerful kind is identical to the submersible type in terms of performance. In contrast, the deep well jets are incredibly strong and have the maximum suction power available. These reservoir drainers are equipped with jet units that may be installed below the water level and raise water from a distance of normally 50 feet, but as far as 100 feet with improvements. As a result, with its suction power and a continuous-duty motor connected, it is capable of constantly pouring water for as long as feasible until the water supply is exhausted.

How The Well Tank Influences The Pump And Its Consequences?

What is the relationship between the well tank and the pump, and what are the consequences? We’ve spoken a little about how reservoir tanks impact the amount of water that is pushed upward. The tank’s water system limits the amount of time it may be left running without stopping. The larger the well tank, the greater the amount of water it can contain. As a result, the longer it can give water constantly, the better. You may operate the machine for as long as you need if you choose a pump with a bigger suction capacity.

Running it non-stop for an extended period of time will cause it to overheat and limit its useful lifetime. The air compartment in these tanks prevents water from entering and clogging the system, necessitating the replacement of the tank.

How Long Can A Sump Pump Run Continuously?

If your sump pump is running continually, it may be a sign that something is really wrong. Sump pumps can become damaged if they are left operating for an extended period of time. To know how long a sump pump can operate continuously is useful information to have. What happens in your sump pit is dependent on the quality of the sump pump and the volume of water that enters the sump pit. Sump pumps of high grade can run continuously for 20-24 hours, whereas low-quality sump pumps can only run for 6-18 hours.

However, there’s a bit more to it than that.

Prevent your sump pump from burning out

Thermal protection is available on newer kinds of sump pumps. When the sump pump motor becomes too hot, the thermal protection prevents it from breaking down. The thermal relay will shut off the sump pump if it is on the verge of failing. As a result, we strongly advise purchasing a sump pump that includes heat protection.

Intermittent vs continuous duty

Sump pump motors are available in two different configurations. There are two types of machines: those built for intermittent duty and those designed for continuous duty. A typical duty cycle of 20 minutes per hour is seen in the ones developed for intermittent duty applications. They can operate for a longer period of time, but this will dramatically reduce the sump pump’s lifespan. The ones built for continuous duty can operate continuously for up to 24 hours at a time. Liberty Pumps 247 is an example of a sump pump that works in this manner.

In other words, a continuous-duty sump pump is only required if there is water in your sump pit at all times of the day and all of the night.

The dangers of a sump pump running continuously

Consider whether there is a valid cause for your sump pump to be running all of the time. If it isn’t raining and your sump pump won’t shut off, there is an issue with your system. For a variety of reasons, sump pumps will continue to operate indefinitely. First, determine whether or not your switch activator is jammed. The majority of the time, this occurs with sump pumps that employ a float activator. It is possible that your switch has become jammed, causing the sump pump to believe that there is water in the sump pit.

If the valve is damaged, water will flow back into the system.

It is possible that the sump pump will overheat as a result of this. It is possible that your sump pump will run continually if it is not fitted properly. Make certain that your discharge lines are on a little slope in order to avoid flooding.

Related questions

The average lifespan of a sump pump is how long do you think it will last? It is dependent on the model you purchase and the manner in which you maintain it. Despite the fact that a sump pump has an average lifespan of 10 years, manufacturers recommend replacing your sump pump every five years. Is it typical for a sump pump to operate nonstop all the time? In the wet season, it is recommended that the machine run for no more than 24 hours before stopping. It is not recommended that your sump pump operate constantly during the dry season.

In what range does the cost of replacing a sump pump fall?

If you are installing the sump pump yourself, you will only be responsible for the cost of the sump pump, which typically ranges between $100 and $200.

  • Running toilet or sink
  • Loss of prime
  • Faulty pressure control switch
  • Leaks in the water system
  • Water level drop
  • Broken well pump
  • And other problems

Pumps used in residential well water systems draw water from your well and pump it into a pressure tank located within your home to provide you with drinking water. Well pumps are intended to fill your pressure tank to capacity, after which they are to be turned off until additional water is required in the tank to fill the tank. The persistent operation of your well pump indicates an issue that should be addressed immediately. There are a variety of reasons why figuring out why your well pump is operating continually is crucial.

It might also be a symptom of a larger problem with your well or water distribution system.


No, a well pump should not be running continuously; if it is, there is an issue with the water system that has to be addressed. Well pumps are meant to work for a period of time before shutting down once the pressure tank is filled. To ensure that the toilet tank fills completely after flushing, the water supply to the toilet should be switched off as soon as it does. If your toilet tank is not functioning properly and the water continues to flow, this places a demand on your water tank, which in turn causes the well pump to continue to operate.

Make necessary adjustments or replacements to your toilet.

Faulty Pressure Control Switch

All water pressure tanks are equipped with a pressure control switch, which monitors and controls the pressure in the well pump to ensure proper operation. When the tank is turned on and off, the water pressure in the tank is controlled by this valve. If the switch is broken or blocked, the pump will not receive a shut-off signal from the control switch and will continue to run indefinitely. This issue can be resolved by unclogging the switch or by replacing it entirely. If you have the necessary expertise, you may repair the pump yourself, or you can hire a plumber.

Leaks in the Water System

A leak in the well pump system might cause the pump’s capacity to be exceeded. The drop pipe, which is attached to a submersible well pump, may develop leaks at some point. Even a little hole can prevent water from flowing through the pipe and into the pump in the intended manner. This will result in the pump being unable to build up adequate pressure, but it will continue to operate. Leaks in the pipes that carry water from the pump to the house will also result in similar issues. A plumber can find the leaks in the system and repair them if they are found in the right place.

Similarly, a fall in water level might be the reason of a well pump that operates continuously. Because of drought or increasing water consumption in your region, the water table in your area may have dropped.

Will a Submersible Pump Run without Water?

Have you ever wondered if a submersible pump can function in the absence of water? When it comes to pumping water into your home, a well pump is very necessary. Watering systems make use of centrifugal force in order to propel water from a well directly into your residence. What will happen, though, if a submersible pump is operated without the presence of water? Is it still going to be able to run? The solution will be revealed farther down the page. Will a submersible pump function properly if there is no water present?

When utilizing submersible pumps, you must exercise caution and ensure that the pumps are completely immersed in water before operating them.

When the water level falls below the intake screen, the water level is considered low.

Can I Use Submersible Pump Out of Water?

Submersible pumps should not be taken out of the water since they are designed to be completely immersed in water. If you use the pump while it is not submerged in water, the motor will spin at a quicker rate than typical, which might cause damage to the pump’s internal components. While it is true that the system may be able to manage the considerably greater speed for a few seconds, it will eventually become damaged since it was not designed to run at that pace for an extended period of time.

How Long Can a Submersible Pump Run without Water?

The pump will not be damaged if it runs without water for less than 45 to 60 seconds. If it runs without water for longer than that, the pump will be damaged. Running the pump dry for a few seconds is acceptable if it is being used to transfer tank contents and the tank has to be completely emptied. If you intend to run the pump dry, you must ensure that it is kept running for a minimal length of time and for no more than 60 seconds, otherwise the pump will be destroyed if it is left running for an extended period of time.

Can a Submersible Well Pump Run Dry?

This will have to be determined by the sort of submersible pump that you are using. There are several types of household submersible pumps available, including those with an o-ring seal, a single mechanical seal, and a lip seal. Pumps of this sort are incapable of running dry. Many industrial submersible pumps, on the other hand, are fitted with double seals that include lubricant, which allows them to safely operate without water for a limited period of time.

What is Dry Running?

Dry running is the term used to describe the operation of a pump when there is insufficient liquid present. The use of dry running can cause an increase in flow and pressure, as well as overheating, which can result in pump failure. Dry running, which may occur when a pump works without the proper amount of fluid, has an impact on the majority of pump designs.

The cavitation and serious damage to the internal components of the pump are possible consequences. The lobes, impellers, bearings, gears, seals, and casings are often the parts of the machine that are most vulnerable to damage when it is used in dry conditions.

What Happens if a Submersible Pump Runs Dry?

It is possible for a submersible pump to get damaged if it runs out of water. The melting of the shaft, which causes the impeller to seize in the shaft, damage to the rear housing of the pump, and damage to the seals are all potential problems that might arise. Repairing a pump that has been damaged by dry running can be time-consuming and expensive, since certain components may need to be replaced.

The Impeller Melts along the Shaft

A problem that might arise when a pump is run dry is that the impeller can melt along the shaft. This is one of the most common difficulties. As a result, the impeller will grip onto the shaft, stopping it from rotating and forcing it to come to a complete halt. You will need to disassemble the pump and use an adrill bit to clean out the bore of the impeller in order to resolve this issue.

It can Damage the Rear Housing of the Pump

Dry running can also cause damage to the back casing of the pump, which is a common occurrence. Because of this deflection, some of the liquid may escape, and in certain cases the boss of rear housing that clamps the pump shaft may bend, causing the shaft to move rather than remain fixed. Because of this, the impeller may be damaged, and the shaft may get separated from the impeller.

It Can Damage Seals

Dry running can also cause damage to the seals, which can result in the engine overheating and failing. In order for a pump to be harmed by dry running, a variety of conditions must be taken into consideration. These include the following: These considerations include the size of the pump, the size of the bore, and the type of fluid that is utilized in the pumping system. In most cases, it takes as little as 30 seconds of dry running to cause damage to the pump to fail. You might also want to read this article, which outlines the reasons why submersible pumps fail.

What Causes Dry Running?

The most prevalent reason of dry running is a misunderstanding. This is due to the fact that dry running is linked to the manner in which the pump is operated, managed, and monitored. In most cases, firms rely on the users to keep an eye on the pumps. On the other side, there have been cases where the pump has been kept running for an extended period of time after the planned procedure has been carried out. Example: The pump is left running while the water level in the tank is being evacuated, and the pump continues to operate even after the tank has been completely emptied.

How to Prevent Dry Running?

Often, human mistake is the root cause of dry running. The reason for this is that dry running is linked to the manner in which the pump is operated, monitored, and managed. Companies typically rely on customers to keep an eye on their pumps. Some occasions on the other hand, when the pump is left running for an extended period of time after the intended operation has been performed.

Example: The pump is left running while the water level in the tank is being evacuated, and the pump continues to operate even after the tank has been completely depleted of its water. There is a possibility that this will cause harm to the pump’s internal workings.

How Long Can a Submersible Pump Run Continuously?

A submersible pump with a continuous-duty motor can work constantly for up to 20 minutes at the most, depending on the application. Of course, the amount of time required will vary depending on the type of pump that you have. Submersible pumps are widely utilized in industry and commerce for a variety of applications. The pipes of the pump have the capability of sucking water from a depth of 25 feet down. Since the pump has more suction force, it may be used for both shallow and deep reservoirs, allowing for more versatility in application.

As well as that, we have published the following article: Can submersible pumps run horizontally?

Can You Leave a Submersible Pump Underwater?

The use of submersible pumps has the benefit of being able to be submerged underwater and yet perform properly. When looking for water pumps, you may discover models that can only be used when completely immersed underwater, as well as models that can be used even when put on a dry surface, such as submersible pumps. When it comes to draining water, submersible water pumps perform the same functions as normal water pumps, but there are several benefits that you can take advantage of with submersible water pumps.

How Many Years Does a Submersible Well Pump Last?

In general, the endurance and quality of a submersible well pump, as well as the amount of use, care, and maintenance that you offer, will determine how long it will survive. Submersible well pumps have an average lifespan of 8 to 10 years before they need to be replaced. Well pumps, on the other hand, can survive up to 15 years if they are only used for moderate water use.

How Often Should My Submersible Pump Turn On?

How long should a shallow well pump run?

30 seconds to 1-2 minutes is a reasonable range. It is most often the case that a well pump will operate continuously and will not shut off because it is unable to generate enough pressure in the system to trigger the pressure switch to turn the well pump off. Another possible reason might be a leak in the piping that runs from the well to the house or apartment complex. Also, why isn’t my shallow well pump shutting off when I tell it to? When the pump is running, a bad leak anywhere in the wellpiping between the buildingwaterpressure tank and the bottom of the well can leak enough water that the pump will not be able to raise the pressure in the pressure tank to the cut -out level, and the well pump will continue to run indefinitely.

Therefore, the question of how far a shallow well pump can pull water may also be raised.

How long can you let a well pump run?

Approximately two and a half hours Continue reading for the whole response. If you want to be away from your house for an extended period of time, turn off your well pump before leaving so that if an electrical problem arises, it will not continue until you return. Prevent water damage and potential health issues by following these steps: While you are gone, your water pump may develop leaks, or a pipe may burst, causing flooding. Aside from that, Is it possible for a well pump to run continuously?

However, if a faucet or toilet is left running all of the time, it will result in your well pump running all of the time as well.

23 Related Question Answers Found

When a well pump runs continuously and refuses to shut down, the most typical cause is that the well pump is unable to generate enough pressure in the system to signal the pressure switch to turn the well pump off. The most typical reason for this is a hole in the drop pipe that leads down to the well.

What causes a well pump to burn up?

It is possible that the pressure switch will activate when there is too much water in the tank and not enough air. This will cause the pump to operate in brief bursts for just a few minutes at a time. This is referred to as “short cycling,” and it has the potential to quickly deplete your pump’s energy.

How far can I pump water from a well?

Your well pump should not be running all of the time. In fact, if you have this problem, you will see a significant increase in your power cost very rapidly. The fact that it is doing so, or the fact that it is cycling on and off frequently, may be a symptom of an underlying problem with the system.

How far away from a well can you build?

Some operations, according to the law, need a protective zone of more than 50 feet.

Generally speaking, personal drinking water wells should be located at a minimum horizontal distance of 10 feet and preferably 25 feet away from property lines or other physical limits. State or municipal requirements may be less or more strict in your location, depending on the circumstances.

Why is my water pump not shutting off?

The pressure switch is the most likely culprit when it comes to a pump that won’t shut off. You will find it to be a little box that is hooked to the water line and has electrical cables coming from your water pump to it. It is utilized to switch on the pump when the pressure drops below a certain level (about 40 PSI) and to turn it off when the pressure rises over a certain level (around 60 PSI).

Posted on April 3, 2019Blog 0 Comments Every home well system is powered by an electrical pump, which serves as its brain. A pressure tank is positioned within your home, and it is responsible for taking water from your well and transferring it to the tank inside your home. In an ideal situation, the pump should only have to operate for as long as it takes to fill the pressure tank. Only when the water level in the tank falls below a certain level will the pump be activated once more. Unfortunately, in the real world, things do not always go as easily as they should.

Higher-than-expected energy costs, as well as costly breakdowns, are just a couple of the consequences of this unwelcome phenomena.

The most effective method


Before you can start pumping water up from your well, you must first prime the pump, which is located above ground. Filling the drop pipe with water is the first step in priming. It is this water that permits the pump’s suction to be transmitted to the water contained within your well, and vice versa. If this is not done, the pump will simply be unable to create the appropriate amount of pressure to increase the water levels. If a well pump is kept dormant for a lengthy period of time, it will eventually lose its prime by nature.

An electric pump may be primed through its priming plug, utilizing either water held in the pressure tank or water from a local water source, depending on the circumstances. If you have a suspicion,


Pressure switches, which are found in all well water pressure tanks, are critical components that must be maintained at all times. Indirectly monitoring the water level in your tank is accomplished by the pressure switch, which registers the pressure in the tank. Even if the water level of the tank declines, a pressure tank can retain enough pressure. It is inevitable that the water level will drop to a point where it will begin to have an effect on the tank’s pressure. As soon as the pressure drops below a pre-determined level, the pressure switch engages, transmitting an electrical signal to the well pump, causing it to activate.

A blocked switch, on the other hand, may be unable to detect changes occurring inside the pressure tank.

This is a problem that occurs frequently.

Pump Run and Off Times – Cycle Stop Valves, Inc

The inrush current generated when a motor is first started generates heat in the motor’s core. In order for this heat to pass to the motor’s skin and evaporate into the water, the motor must be running for approximately one minute. Then, when the pump shuts off, the motor is still heated, and it takes approximately one minute for the motor to cool down to the point where it is safe to restart the pump. As a result, the minimal rule of thumb has always been one minute on and one minute off. Two minutes on and two minutes off is a significant improvement in the health of the motor.

Posted By:restorodderon 11/17/10 03:19pm I have heard it over and over again,”the pump will burn up if run without water”. Well today I went out to the motor home, to place a light bulb in the water bay(to make sure the sewer lines don’t freeze),and found the pump running. It was real quiet because it was not pumping anything. I winterized the coach last week,before I took it to a repair shop,for warranty work.Monday on the trip home I stopped at a rest area and used the toilet,then flushed with antifreeze.

Tuesday I worked out in the MH and flushed again,then left the coach until this afternoon.

The pump was warm,but when I connected it to another bottle of antifreeze it started pumping then shut off when it built up pressure.

I went inside and checked the pressure,it seems Ok.
