Why Does My Water Pump Keep Turning On And Off

What You Can do to Prevent Excessive Cycling on Your Water Pump

A water pump with a short cycling cycle indicates that the pump shuts on and off too rapidly. For those of you who are experiencing this issue, here are the four most prevalent causes of short cycling pumps to consider:

Insufficient Air Charge In The Water Tank

Most of the time, a loss of air charge within your water tank is the root cause of brief cycling. For older versions and non-bladder type (also known as captive air tanks) water pressure tanks, this is a very typical problem to encounter. The bladder of newer bladder-type tanks may potentially acquire this problem if the bladder is damaged in any way. Here are three possible solutions you might want to consider (steps 1 and 2 are for non-bladder style tanks) 1. Replace the tank air volume control with a new one.

3) Empty your tank of water, and then use the air intake valve to re-inject air into it.

Defective Water Pump Pressure Control Switch

The most typical reason of brief cycling is a loss of air charge within your water tank. For older versions and non-bladder type (also known as captive air tanks) water pressure tanks, this is a very typical issue to experience. When the bladder of a newer bladder-type tank is destroyed, this problem might occur as well. You may need to attempt three different remedies (steps 1 and 2 are for non-bladder style tanks) First, check the tank air volume control for malfunctioning. 2. Allow air to return to the water tank by draining the tank completely.

You should have 2 psi less pressure in the air charge than the pressure at which your pump cuts in.

Blocked Water Supply Piping

The most typical reason of brief cycling is a loss of air charge in your water tank. For older versions and non-bladder type (also known as captive air tanks) water pressure tanks, this is a very typical issue to encounter. When the bladder of a newer bladder type tank is broken, this problem might occur as well. Here are three possible solutions you may want to consider (steps 1 and 2 are for non-bladder style tanks) 1. Replace the tank air volume control with a working one. 2.Drain the water tank and open the tank to allow fresh air to circulate.

The air charge should be 2 psi lower than the pressure at when the pump is activated.

Irrigation Zones Are Too Small

Because of the low flow rate of an irrigation pump, the pump might reach its cut-off pressure relatively rapidly if utilized for irrigation purposes. This occurs most frequently in zones with modest or low flow rates, such as drip irrigation systems. Running the little low flow rate zones in parallel with another zone is generally sufficient to remedy the problem.

Because of the greater flow rate, the pump may be activated earlier and remain operational until the irrigation cycle is complete. Contact W.P. Law, Inc. if your water pump is not working properly.

Why does my water pump keep shutting off?

Asked in the following category: General The most recent update was made on April 24th, 2020. There is a clog in the water supply piping. An overloaded or almost overloadedwaterfilter, for example, might cause thepumpcontrol to cycle on and off repeatedly and cause damage to the pump. This is due to the fact that when the pump is turned on, the obstruction causes the water pressure (between the pump and the filter) to rise extremely quickly. It has been shown that the most prevalent reason of water pump short cycling is a lack of sufficient air charge in the water tank.

  1. In a similar vein, having too much air in the tank (overcharging) might cause the water tank to cycle for too short a time.
  2. A variety of factors might contribute to short riding sessions.
  3. This is especially prevalent in older pressure tanks that do not have bladders.
  4. As a result, why does my water pump continue to trip the circuit breaker?
  5. (Photo 1 of 3) There is a 1/4-in.
  6. If the switch is faulty, it will not start the wellpump, and you will not have water, thus checking the switch should be your first step to ensure that it is working properly.
  7. If it appears that a bladder tank is not performing properly, the air charge in the tank should be checked:
  1. The electrical power to the pump should be turned off. The tank should be drained by opening the nearest faucet
  2. Inspect the tank’s pressure by attaching an air pressure gauge to the tank’s air charging valve, which is located at the very top.

What Causes Your Water Pump To Short Cycle?

Power should be disconnected from the pump’s electrical supply. The tank may be drained by opening the nearest faucet; To check on the tank’s pressure, attach a digital air pressure gauge to the air charging valve, which is located at the top of the tank.

Common Causes Of Water Pump Short Cycling

Lack of adequate air charge in the water tank is a problem (And Overcharging) One of the most prevalent causes of water pump short cycling is a failure to maintain an appropriate air charge in the water storage tank. This issue is particularly prevalent in older homes that have non-bladder water pressure tanks that do not function properly. However, the good news is that this specific issue may be resolved pretty quickly. It entails restoring the water tank’s air volume control (if one exists), pumping air into the tank through the air intake valve, and then emptying the water tank to remove any remaining water from it.

  • Additionally, having too much air in the tank (overcharging) might cause the water tank to cycle for a shorter period of time.
  • The sort of water tank you have will determine how to resolve the issue.
  • Pipes for water supply are clogged.
  • An even slightly blocked water filter might cause cycling to be slowed down significantly.
  • The cartridge must be replaced if this is the root cause of the short cycle time.

Water Pumps Switching On and Off

When there is a problem with a water system, the water pump may begin to switch on and off by itself. If the underlying reason is not addressed, this might become a persistent issue. It is possible that it will start off gently and worsen over time. “Cycling” is the term used to describe a pump that is constantly switching on and off. The sound can be quite irritating, but worse than that, if the problem is not identified and corrected, the pump may be permanently destroyed. In this section, we’ll look into water pump cycling, including what causes it and how to stop it.

Pumps are operated by internal pressure switches

Pumps that are continually switching themselves on and off are known as pumps that are operated by pressure switches within the device. It is only once we grasp how these switches function that we will be able to comprehend the reason why our pump is continually switching itself on and off. In order for a water pump to function, it must be powered by an electric motor that turns an impeller (which is similar to a fan in an enclosed housing, I suppose), which draws water from your well or tank through an inlet pipe and pumps it out through an outlet pipe, delivering it to the faucets, toilets, and showers in your home.

  1. The first, the low pressure switch, requires that there be pressure in the water in order for it to remain switched off.
  2. When the water pressure becomes excessive, the second switch, known as the high pressure switch, is activated.
  3. We release the pressure in the water pipe when we open the tap, and the low pressure switch in the pump detects this and activates the water pump to provide the water.
  4. During this time, the pump continues to work for a fraction of a second longer until the water pressure in the pipe increases to a level sufficient to activate the high pressure switch, which shuts down the pump.

Pressure switches must be set correctly

Of course, we can modify the settings on both of these switches in order to determine the amount of pressure we have in our shower. Normal water pressure settings are roughly 20 psi or 1.4 Kg/sqcm (Kilograms per square centimetre) for the low pressure switch and 40 psi for the high pressure switch, however some individuals prefer greater water pressures than this. It is possible that if these pressures are placed too close together, simply little fluctuations in water pressure will cause the pump to turn on and off.

Is your water pump too large?

One little shower will not be able to keep up with the high amount of water that is being supplied by your water pump if you have a large water pump. Turn on the shower and the water starts to flow, relieving the pressure in the pipes and allowing you to turn on your water supply pump. However, because the water cannot escape from your shower head quickly enough, the pressure in the water line builds up, causing the pump to shut off abruptly. The shower head can now catch up with the flow of water, and the water pressure lowers once again, causing the pump to turn on once more.

Water flowing from your shower will pulse when the pump switches itself on and off, which indicates that this is happening.

If you have a big number of restrooms, utilize numerous smaller pumps rather than a single large one to save space. If you are serving restrooms on more than one floor level, this is very important to consider since you will require more pressure to pump water up to the second story.

Adding a pressure tank to your water system

However, there is a method to get around the difficulty of having a huge pump serving a small faucet or shower head. We also include a pressure tank, which is often known as an accumulator. You’ve probably seen water pumps with a painted steel canister attached to them. The canister is typically 20 cm in diameter and 30 cm in length. Water is difficult to compress, as it compresses only a little amount when compressed. The fact that water does not compress means that just a few droplets of water are required to relieve the pressure from a water pipe before the pressure begins to decline.

  1. Despite the fact that a considerable amount of air is present, the variation in pressure will be minimal.
  2. This is referred to as a pressure tank in the industry.
  3. Whenever we turn on the shower, the air in the tank will gradually expand, forcing the water out of the shower until the pressure in the tank decreases to a level at which the pump turns on and begins to pump the pressure back into the tank once again.
  4. Pressure tanks require regular maintenance, and occasionally air leaks from the tank, necessitating the tank’s re-filling with compressed air.
  5. In any event, once the air is lost, the pressure tank will cease to function, and the pump will begin to cycle on and off incessantly once more.
  6. If there is a tiny loss of water, the water pressure in the pipes will be reduced fast, causing the pump to activate.
  7. Then another tiny quantity of water seeps out, the pressure lowers, and the pump is forced to turn on once again to compensate.
  8. The smaller the leak, the slower the clicking is done.

Water tank ball valves and level sensors

However, there is a method to get around the difficulty of having a huge pump serving a little tap or shower head. An accumulator, sometimes known as a pressure tank, is added to the mix. A painted steel canister with a diameter of 20 cm and a length of 30 cm will be familiar to you if you have ever seen a water pump with one connected. Water is difficult to compress, and it compresses only a small amount when it is compressed. The fact that water does not compress means that just a few droplets of water are required to relieve the pressure from a water pipe.

  1. Despite the fact that a huge amount of air is present, the change in pressure is relatively marginal.
  2. As a pressure tank, this is what we call it.
  3. Whenever we turn on the shower, the air in the tank will progressively expand, forcing the water out of the shower until the pressure in the tank decreases to a level at which the pump switches on and begins to pump the pressure back into the tank once again.
  4. Pressure tanks require regular maintenance, and occasionally air leaks from the tank, necessitating the tank’s re-filling with air.
  5. Whatever happens, after the air is exhausted, the pressure tank will cease to function and the pump will begin to cycle on and off constantly once more.
  6. If there is a minor loss of water, it will immediately lower the water pressure in the pipes, causing the pump to activate.
  7. An further tiny quantity of water seeps out, and as a result, pressure lowers and the pump is activated once again.

There are several different reasons for water pumps to cycle – to alternate between turning on and turning off repeatedly, and sometimes quite fast. The leak is smaller the slower the clicking is.

How to find out why your pump is switching on and off

In other words, if your pump is frequently switching on and off, the most likely cause is a minor leak in your water supply. Try this: walk around the home and make sure that everything that requires water, whether hot or cold, is turned off and unplugged. Is the pump still turning on and off at random? If it is, double-check to make sure there are no toilets running or faucets dripping; examples of such items are a leaky jet washer in the toilet or the pressure release valve on your water heater, which is particularly important if you have a solar water heater on your roof.

  • There is a leak in your system that is allowing pressure to escape.
  • If you don’t have a dog, walk around the garden and look for signs of water leaking, such as a patch of overgrown vegetation (usually a giveaway) or wet patches on the driveway when you don’t have one.
  • Try shutting off the stop cocks in the piping system to see if you can identify the section of the pipework that is possibly leaking.
  • Consult with him to see whether the water pump pressure switch settings are too close together.
  • If the bladder is ruptured, it will need to be replaced, which is a very inexpensive procedure.

9 Common Well Pump Pressure Switch Problems

Is your water supply getting low? It is possible that you are experiencing pressure switch issues. Over 34 million people in the United States rely on wells for their water supply. In order to save time and money, well owners prefer to discover and resolve concerns themselves, if feasible. We’ll look at how a pressure switch works, some easy troubleshooting suggestions, and nine commonwell pump pressure switch issues in the sections below.

How a Well Pump Pressure Switch Works

It is vital to understand how a well pump pressure switch operates in order to properly diagnose pressure switch problems. In essence, your pressure switch instructs your well pump, which is responsible for delivering water to your residence, when to turn on and off. It accomplishes this by continuously monitoring pressure and allowing extra water to flow into the system when the pressure drops below the minimal PSI level (pounds per square inch). When the maximum PSI is reached, it automatically shuts down.

It is composed of an internal spring mechanism that is directly coupled to electrical connections, and it is used to alter pressure. As the pressure switch ages, these components may get weaker and malfunction, necessitating the replacement of the switch altogether.

What to Check Before Diagnosing a Pressure Switch Problem

First, check to see if there is something more visible wrong with your pressure switch before you begin analyzing it. Here are a number of things to keep an eye on:

  • Check to be sure that electricity is being sent to your well and that there isn’t a short
  • Ensure that the water pump breaker in your electrical box has not been tripped by checking the breaker’s status. If it has tripped, you will want to look into what may have caused it to do so. An intermittent tripping condition might be caused by a damaged wire leading to or within the water pump. Check the pressure gauge in the well tank to make sure it is at least 40 PSI (or the cut-off PSI for your pressure switch model). Make sure your filter isn’t blocked or that it has to be replaced if it isn’t working properly. Ensure that the pressure gauge is not jammed or damaged by performing the following checks:

After you’ve eliminated the possibility of the water pump and other components, you may turn your focus to the pressure switch for the water pump.

Common Problems with Your Well Pump Pressure Switch

Here are nine of the most typical problems you’ll encounter with your pressure switch, listed in no particular order.

Switch Won’t Turn On

If your switch would not turn on, it might be because the pressure in your tank is greater than the cut-in pressure of the switch. Try running some water in another part of the building to bring the pressure down below the cut-in level for a while. You may also try lightly tapping on the pressure gauge, the switch, and the tank to see if it helps to relieve the pressure.

Switch Won’t Turn Off

There are a variety of issues that might prohibit a pressure control switch from going off. When this occurs, it is critical to turn off the power so that the switch does not burn out. Investigate whether your well is providing enough water, and whether there are any leaks that might be interfering with your pressure cut-off.

Switch Won’t Turn On or Off

As long as the well water pump isn’t producing enough pressure to activate the pressure switch, the switch will remain in the off position. Aside from examining the pump, make sure your water pressure gauge is operational before diagnosing a problem with the pressure switch.

Switch Clicks On and Off Repeatedly

If your pump appears to be cycling (i.e., turning on and off frequently), there are a few possible reasons. A blown bladder in the water tank is one of the most common causes of water leaks. In addition to replacing this component, you should check the switch contacts to determine whether they’ve been damaged as a result of the cycling. Leaks in the well system might cause your pressure switch to cycle too quickly, causing the switch to be damaged as a result.

Pressure Sensor Clogging

If you reside in a region where the water has a high mineral content or contains sediment, your pressure sensor may get blocked over time. Clean the tubing that links your switch to the water supply and see if it helps. It is possible that you may need to clean the bottom of the switch itself. Generally speaking, though, if you have enough dirt to produce a blockage, it is more cost effective to replace the switch.

Damaged Diaphragm

The pressure created by the water from your supply acts on the diaphragm of the switch, resulting in a pressure readout. Because of the age of the diaphragm, wear and tear might make it incapable of sensing the necessary water pressure. If this happens, it is necessary to purchase a replacement switch.

Failed Connection

The pressure created by the water from your supply acts on the diaphragm of the switch, resulting in a pressure value being displayed. Because of the age of the diaphragm, wear and tear might make it incapable of sensing the right water pressure when necessary. A replacement switch should be purchased if this occurs.

Bad Contacts

Over time, the electrical connections in your pressure switch may become less effective. The presence of corrosive chemicals and the frequent cycling of electricity to the switch are two of the most typical culprits.

You may perform a temporary repair to contacts by filing away the damaged area; however, you must first turn off all power to the pump before you can do so. You’ll need to replace the switch if you want a more permanent solution.

Water Is Leaking from the Internal Mechanism

It is possible to tighten the switch’s plumbing connection by twisting the brass fitting clockwise using plumber’s pliers. If you see water leaking under the switch housing or from the switch itself, contact a professional. Even if you are still experiencing leaks, it is most likely due to a malfunctioning internal mechanism. In this case, the pressure switch will need to be replaced.

Identifying Well Pump Pressure Switch Problems

After learning what to look for, you should be able to spot seven of the most frequent well pump pressure switch problems — and even prevent them from developing in the first place. In the long run, proper maintenance will save you both money and heartache. Having trouble determining whether or not your pressure switch is defective? For a second perspective, consult with a well pump contractor with extensive expertise in your region. The experts can quickly replace your switch if you are not confident in your ability to do it yourself.

well pump keeps turning on and off every few seconds

60k people have viewed this question. When I woke up this morning, the water that was being used to flush the toilets in the home was contaminated with dirt, mud, and silt. Upon further inspection of my well pump system, I discovered that the pressure switch is constantly switching the pump on and off every second or two. As soon as the pump is turned off by the switch, the water in the pressure tank is released and returns to the well/pump through the discharge line. After a sufficient amount of pressure has been dropped, the switch activates the pump once more.

  • It is my belief that the water draining back down into the well is causing dirt to be stirred up in the well, resulting in dirt being deposited in the water in my toilets because the water line to them is not filtered.
  • It appears that a check valve or something similar should be installed to prevent the pressure in the pressure tank / line from leaking back towards the well, as shown in the diagram.
  • Alternatively, it’s possible that the pressure switch failed.
  • It seems as though the switch should have shut down the pump sooner rather than later.

EDIT: Here’s a video showing the behavior (the action begins at 4:10): list=UU-PYeNYSUiTfiH1ZfcD9 cw (the action begins at 4:10) EDIT 2: Here’s a video showing pressure behavior when two outlets are opened and water is allowed to flow (pressure remains at 56psi when the pump is turned on): list=UU-PYeNYSUiTfiH1ZfcD9 cw And here’s some additional information: I measured the tank pressure with the pump turned off and the pressure on the line set to 0 psi.

  1. The pressure was approximately 65 psi, so I’m assuming the bubble/bladder isn’t too terrible.
  2. Any assistance, advise, or recommendations you can provide me will be much appreciated!
  3. asked November 18, 2014 at 11:44 a.m.
  4. Everything is wrong here, and while there is a brief list of things that one would generally look for with excessive short cycling (such as a blown bladder in the pressure tank), this does not address the 90 PSI issue.
  5. If your system is properly configured, it is possible that there is another one within the house, which would imply that it is also dangerous.
  6. When it stops working, it’s time to start pulling the pump.
  7. In a few years, I’ll place a new pump on the shelf for when this one finally fails, so that I don’t have to make a last-minute purchase when (not if) I need one.

At least on my well, the emergency relief valve opens when the pressure reaches 100 PSI.

In an ideal world, you’d already know what your default setting is, or it might be documented on a sticker someplace on the device.

You may TRY connecting a garden hose to the valve and opening it, then turning on the pump to clean away the muck that has been churned up.

At the very least, it will clear the well of the sludge that has been stirred up while the pump is being fixed or replaced.

Are you perplexed as to why your well pump is operating nonstop? We’ll be happy to assist you in troubleshooting this plumbing issue. In most cases, if your well pump continues to operate, it is due to one of the following problems:

  1. You have an appliance that is up and running
  2. It’s possible that the well pump has lost its prime. The pump pressure control switch is not working properly
  3. It’s possible that the water level has lowered. There are leaks in the well plumbing. Your well pump is no longer working properly.

Let’s go over each of these six typical well pump issues in further detail, as well as how to resolve each of them.

1: You have a running appliance

If you have an item that is always in use, such as a toilet or sink, your pump may likewise be constantly in use. This is due to the fact that a running appliance needs a continuous flow of water, which pushes your pump to work continuously. Observation: A toilet and a kitchen sink are two popular household plumbing equipment that are prone to running continuously. More information on how to remedy them may be found in the following articles:

  • What is causing my toilet to run constantly or randomly
  • Why is my kitchen faucet refusing to turn off?

Method of investigation: Use the following methods to determine whether a running appliance is causing your well pump to operate constantly:

  1. Turn off the water supply to your home at the main valve. If your pump ceases to operate after you have turned off the main water supply, it is possible that one of your plumbing fixtures is consuming an excessive amount of water. Replacing the main water supply is the first step, followed by checking plumbing equipment like as sinks, showers, and toilets, as well as exterior garden hoses and lawn sprinklers, to ensure that they are not continually running or leaking

If you have any leaks or an item that is continually running, make sure to have them repaired (you may need the assistance of a plumber to do so). Check to see if your well pump is back to normal operation after you have repaired any leaks. If your well pump is still functioning, it is possible that you have another problem. If that’s the case, continue reading.

2: The well pump may have lost prime

Pump systems come in two varieties: an above-ground jet pump system and an underground submersible pump system. Above-ground jet pump systems are more expensive than subterranean submersible pump systems. The loss of prime at the well pump is normally only an issue with a jet pump system, which is uncommon. In order to create enough suction to pull water out of a well and into the home water line, the intake pipe on a jet system must always be filled with water (primed), which is referred to as “priming the pump.” If your well pump loses its prime, it will continue to operate continuously.

Solution: First and foremost, turn off the pump as soon as possible to prevent damage to the pump.

Even while you can attempt to prime your jet well pump on your own, it is recommended that you contact a plumber since the suction line may have a leak, which a professional should repair or replace.

3: The pump pressure control switch is faulty or set incorrectly

The pressure control switch is responsible for regulating the pressure in your water well pump. Further, the switch is in charge of regulating the water pressures that cause your pump to cut-in (turn on) and cut-out (turn off) (turn off). It is possible for your pressure control switch to be malfunctioning (typically as the consequence of blocked tubing or burnt contact points), or for someone to have altered the cut-out pressure to be higher than the pump’s capacity, causing your pump to operate indefinitely.

In order to adjust your pump’s pressure settings, you may need to remove the cover from the switch, which can be dangerous due to exposed live wires near water. Only a skilled expert should perform this task.

4: The water level may have dropped

In order to perform effectively, your well pump requires a consistent flow of water entering the pump at a consistent rate. This is referred to as the flowrate. If the water level has dropped too low, or the flow rate is incorrect, your well pump will continue to run continuously without shutting off. The following are some of the most typical reasons of decreased water level:

  • A decrease in the level of the water table in your region
  • Drought in some areas
  • Increased demand for water

Solution: Consult with a plumber to ensure that your well pump system is operating at the correct water levels and at the proper flow rate.

5: The well piping has leaks

After reaching a particular pressure, your well pump is programmed to shut down automatically. The water pressure in the system is reduced if there is a substantial leak anywhere in the well plumbing. As a result, if the pressure becomes too low, your pump will not shut off and will instead continue to operate continuously. Consult a plumber to examine your well pump system for signs of leakage. A plumber will be equipped with the necessary instruments to locate and repair any leaks.

6: Your pump is damaged

Well pumps, like other mechanical equipment, will eventually wear out and need to be replaced. It is possible for a well pump to suffer internal mechanical damage, which prevents it from raising water pressure beyond the control switch cut-off point, resulting in the pump running non-stop. Repair (or, more likely, replacement) of your well pump should be handled by a plumber.

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 of determining the source of the problem is to contact a professional plumber to conduct an investigation.

Two factors that might cause your well pump to operate nonstop are discussed in this article, which will help you improve your well pump troubleshooting abilities.


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 allow a dry pump to continue to operate, it can eventually overheat and cause other catastrophic consequences.

A well pump that loses its prime on a regular basis is most likely suffering from underlying issues.

A leak in the drop pipe is the most common cause of the problem. In addition to air leaks in either the impeller or the pump casing, broken check valves inside the well pump, and a damaged foot valve at the bottom of your well are also major reasons of well pump failure.


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.

  1. A blocked switch, on the other hand, may be unable to detect changes occurring inside the pressure tank.
  2. This problem is frequently caused by physical material being trapped in the tube that goes to the pressure switch.
  3. In other circumstances, the pressure switch may have simply gotten broken or burned out due to normal wear and use.
  4. Attend to this issue as soon as possible in order to avoid more serious types of harm from occurring.

Why does my pump on my water well keep coming on?

Check for leaks or pools of water if you have access to and a crawl area beneath the home; if so, call a professional. Close off the shut off valve to the plumbing in the house and see if the pump continues to cycle (turn on and off), if it does, you have eliminated the possibility that the house is causing the problem and the leak is most likely in the underground water main supply line. If there is a shut off valve AFTER the pressure tank, that valve can also be closed off to further isolate the leak issue.

Pressure is reduced to 30 lbs of pressure in the pressure tank.

If you have a bladder tank, you are less likely to experience water-logging; however, if you have an older type system and the pressure tank is simply a large (40 or 50 gallon tank without a bladder), you may experience water-logging, which means that the tank has become so full of water that there is very little airspace left in the tank, resulting in rapid cycling.

Because there is so little air space in the tank, the pressures will fluctuate rapidly, forcing the pressure switch to engage the pump considerably more frequently than necessary!) In normal operation, a tank without a bladder or diaphragm should only be half full of water, enabling the other half of the tank, which is filled with air, to compress between the on and off cycles, resulting in a much more equal flo of water with no dramatic pressure variations.

A bladder tank’s diaphragm may have broken or burst if there are no water leaks.

In the newer types of pressure tanks with a diaphragm, a rubber membrane attached to the inner wall of the tank allows it to stretch during the water pump stage towards the air compartment, increasing air pressure until the proper pressure is reached, and then the compressed air pushes back on the diaphragm towards the water compartment, causing the pressure switch to activate.

I hope this information is useful- understanding the fundamentals of how a well and pump system function may save you a lot of money if you can choose whether to hire a plumber, a well repair company, or to discover the faults and do it yourself!

HELP! NO WATER! Pump keeps shutting off.

Let me check to see if I’m understanding what this picture is saying. Please repair all of the errors on this page. The well is located on the far right. The well pump fills an aerator tank, which in turn feeds a pressure pump, which pumps water into a bladder-type storage tank, as shown in the diagram. That’s right, it’s this pump that’s not cycling correctly. The water from the pressure tank is routed via your softener (which you have ruled out as a source of the problem) and into your home.

  1. If that’s the case, here’s what I’d do.
  2. So let’s rule out the possibility of a ruptured bladder.
  3. Let air out of the schrader valve, which is located on top of the pressure tank, starting now.
  4. If this is the case, proceed.
  5. Once all of the pressure has been released, add 5-10 pounds of air to the tank and wait until all of the water has been removed.
  6. (You may need to determine this before proceeding with the rest of the process.) After you’ve completed this, switch your breakers back on and examine the system once more.

Why Is My Well Pump Short Cycling?

Because the well pump is the lifeblood of the water well, when something goes wrong with it, the owners are understandably concerned. Short cycling is a typical problem for well pumps, and well specialists discuss it on a regular basis. Many well owners, on the other hand, are unfamiliar with the term “short cycling.” This week, we’ll go over the concept of well pump short cycling. Continue reading to find out what brief cycling is and what causes it to occur frequently.

So What Is Short Cycling?

When the water pump shuts on and off sporadically, this is referred to as short cycling. It occurs while the owner is attempting to draw water from the well, which causes the cycle. It is a really annoying experience since the pump is randomly interrupting and restarting the flow of water on its own. Several factors can contribute to the inability to cycle for an extended period of time. After that, there are a slew of less likely, but equally reasonable reasons to think this is the case.

Loss Of Air Charge

This is a problem that occurs significantly more frequently in older water wells. In essence, there is a delicate equilibrium between water and air in the water tank. If there is insufficient airflow, the water does not push out at a consistent rate. As a result, the water flow and pump cycling cycle in and out at random intervals. In the vast majority of cases, this is the primary cause of well pump cycling.

Fortunately, in current water pumps, there is a particular bladder for the air, which makes it more difficult to lose the charge of the air. However, if the air bladder is compromised, it is still possible to have a stroke.

The Filter Is Clogged

When it comes to keeping silt and sediment out of drinkable water, well filters put in a lot of effort. Those filters, on the other hand, might become clogged or obstructed from time to time. If the filter becomes completely or even partially clogged, the pump will be unable to draw water from the well at the required rate. The pump will cycle as a result of this. It is turning on and straining to attempt to get the water through the filter, but it is unable to do so due to the blockage in the filter.

You Have A Pressure Switch Problem

In order to keep silt and sediment out of drinking water, well filters work extremely hard. But such filters might become clogged or blocked from time to time. A completely or partially blocked filter will prevent the pump from drawing water from the well at the right rate. The pump will then cycle as a result of this. Due to the blockage, it is turning on and straining to attempt to get the water through the filter, but it is unsuccessful. When it learns that it isn’t drawing any water, it shuts down.

What Should I Do if My Sump Pump Keeps Cycling?

Depending on how you use it, your basement might be anything from a multi-purpose room to a large storage closet. In any case, it is a space that must be secured against the potential of incursion by underground water, which can occur at any time. Sump pumps are responsible for performing this function for you. A sump pump gathers water in a sump basin, and then drives it up a drain line and out to a location where it may be securely disposed of. As previously said, a running sump pump is incredibly crucial in safeguarding your property from the significant damage that subterranean water can do, and it is therefore extremely important to recognize the indicators of sump pump failure as soon as possible.

  1. It is also possible for your pump to become stuck in its cycle and refuse to switch off.
  2. It will also use more energy as a result, resulting in more money being taken from your wallet during the entire process.
  3. In the Chicago region, where the water table is higher than it is in many other parts of the country, this is particularly problematic.
  4. This quick explanation of what causes these difficulties and how to remedy them will assist you in better understanding what may go wrong with your plumbing system.

What Causes a Sump Pump to Short Cycle?

Short cycling is usually an indication of a problem with your pump’s float switch, which is a mechanism that floats on the surface of the water in your sump basin and activates your pump when the water level reaches a certain level. The float switch may become entangled in the electrical cable of the pump, or it may even become entangled against the side of the sump basin’s wall and become stuck there. This means that the float switch can’t move freely in either situation, which might result in the pump becoming stuck in this short cycle or being unable to shut off again once the cycle has ended.

How to Fix a Sump Pump That Keeps Running

Typically, brief cycling is caused by a problem with your pump’s float switch, which is a mechanism that floats on the top of the water in your sump basin and activates your pump when the water level reaches a certain level in your sump basin. When the float switch is not used, it can become entangled in the electrical cable of the pump, or it can become entangled against the side of the sump basin’s wall. This means that the float switch can’t move freely in either situation, which might result in the pump becoming stuck in this short cycle or being unable to shut off again when the cycle has finished.

Well Pump Troubleshooting and DIY Repair

If you own a property with a well, you are aware that problems can arise at the most inconvenient of times, and that after-hours repairs can be quite expensive. A lack of water at all, pulsating water pressure, and a well pump that operates continually are the most prevalent signs of well difficulty. If you are experiencing any of these symptoms, there is a significant probability that you will be able to address the problem yourself. How to Restore a Dead Well (Video)

Project step-by-step (8)

  • Begin by checking to see that thewell switch, which is situated near your pressure tank, has not been turned off. Afterwards, check to confirm that the double-pole circuit breaker for the well has not been tripped
  • If this has occurred, it should be reset.
  • A breaker that constantly tripping indicates a problem with the well pump, which would necessitate the use of a professional to resolve.

Then Check the Pressure Switch

  • The fact that your breaker continually tripping indicates that you have an issue with your well pump, which will require the services of a professional.
  • It is responsible for detecting when the water pressure has reduced to the point that the pressure tank requires extra water to function properly. The well pump is then activated by pressing the switch. If the switch is faulty, the well pump will not be able to start, and you will be without water. Therefore, testing the switch should be your first step.

Removing the cover and slapping a screwdriver handle against the tube below the switch to jar the electrical connections will do the trick. If you detect a spark and the pump begins to run, the pressure switch is the source of the issue.

Pipe dope or Teflon tape should be applied to the tube threads before screwing on the new switch so that it sits in the same orientation as the old one. After that, reconnect all of the cables.

  • Make a pipe dope or Teflon tape application to the tubing threads before installing the new switch so that it is in the same orientation as the old one (see illustration). Connect the wires back together after that.

Temporary Quick Fix

Banging on the tube under the pressure switch activated the pump, which indicates the electrical contact surfaces are pitted or scorched, resulting in a weak connection between the well pump and the pressure switch. You can temporarily restore the surfaces in order to keep the machine running until you can purchase a new switch.

  • To begin, switch off the electricity and double-check the voltage with a voltage tester
  • Use a regular nail file or emery board to open up the contacts and file away the burnt and pitted areas. Please replace the pressure switch as quickly as possible, as this temporary remedy will not work for long.

VERIFY THAT THE POWER IS OFF! Prior to removing the pressure switch or filing the contacts, turn off the power at the main panel and verify the wires with a non-contact voltage tester to ensure that they are not damaged. Step number five.

Replace the Pump Controller

  • Remove the screw at the bottom of the pump control cover and lift it off the box in order to separate the pump control cover
  • Take it to the store and get a replacement that is identical
  • Snap the new cover onto the old box (there is no need to rewire if you get the same brand as the old one)
  • And After that, turn on the pump.
  • The pump controller is equipped with a capacitor that aids in the startup of the pump. The majority of pump controls are located in the home near the pressure tank, but some are located inside the well pump itself, and the repair of these requires the services of a professional. In the event that you do not have the box displayed below, this patch will not work.
  • Given the lack of a mechanism to test the controller, you’re left with two options: either risk blowing $75 by replacing it with a faulty one, or fold your hands and contact an expert. It’s simple to replace the pump controller in this manner, and it’s your last and best chance to prevent having to contact for service. If you’ve tried everything, including replacing the pressure switch, and the pump still won’t start, we believe it’s worth taking the chance and replacing the well pump controller.

Check the Pressure Tank’s Air Valve

  • Remove the plastic cover from the air valve located on the top of the tank
  • Depress the air valve with a little screwdriver to see if any water comes out of the tank
  • Repeat the process.
  • When water “pulses” at the spigot, it’s typically a sign that your tank is clogged with moisture. Replacement is the only alternative available to you. A new tank might cost anything from $200 to $500.
  • In order to diagnose a defective tank, check for water at the air valve and shake the tank
  • Both approaches are effective.

Rock the Tank

  • Pushing on the top of the tank will cause it to rock slightly. If you are unable to rock it or if it seems top heavy, that is a negative sign. It should be drained and replaced.

Hire a Professional

If your pump is always running, it is possible that there is no DIY remedy. It is normal to hear the clicking sound that occurs when the pressure switch opens and closes when a well pump is turned on. Even if there is no water pouring, you may be experiencing difficulties outside the home and will need to call in a professional to help you fix them. Broken water lines from the well to the house (you’ll usually notice some standing water between the well head and the house) are one possibility.

Other possibilities include a bad check valve just above the submersible pump at the bottom of the well, a bad connector coming out of or inside the well casing, or even a broken water line within the well casing itself. Each of these issues need the assistance of a professional.
