Following our description of reasons that a well pump won't stop running (just below) we provide a Table of Diagnostic Steps for a Well Pump that Won't Shut Off
This article series answers just about any question you may have about pumps, wells, and drinking water. Even before performing water quantity, quality, equipment function tests, there is an enormous amount we can determine about a building's water supply just by looking at the equipment.
The photograph at page top shows a one-line jet pump, the water pressure tank, and a water softener. We know from the fact that this is a single line jet well pump that the well is a shallow one, probably less than 27' deep. Well depth may have implications for water quantity and quality and vulnerability to surface water contamination.
Watch out: the first thing to do to protect your pump from damage if it simply wont' turn off is to shut off electrical power to the pump. If the building has no water pressure, turn off the water pump immediately. Running a water pump "dry" risks causing internal damage to the pump. If there is no water pressure, see WATER PRESSURE LOSS DIAGNOSIS & REPAIR.
If your well pump is turning on and off too often, see WATER TANK REPAIRS and further details at SHORT CYCLING CAUSES - why does the water pump keep shutting on and off so quickly? If your pump won't start, see WATER PRESSURE LOSS DIAGNOSIS & REPAIR and PUMP PRESSURE CONTROL REPAIR. At WATER PUMP WONT STOP RUNNING we discuss water pumps that won't shut off.
If your building has some water pressure (check at a nearby faucet) but the well pump keeps on running and won't shut off, that's what we are discussing here. Several problems can cause a water pump to keep running instead of shutting off when it should, and each of these suggests its own diagnostic step to finding out what's happening with your well pump.

Frequently Asked Questions (FAQs) about well pumps that won't stop running
Question: Water pressure drops and well pump never stops
Well starts out ok but within minutes has dropped pressure never does stop pumping water but it sure does get low whats up? - Ken
Reply: what to check when the pump never reaches cutoff pressure
If your pump runs continuously and never reaches cut-off pressure, there are several possible causes (see the table of problems above) such as
- pressure switch cut-out set higher than pump is capable of reaching (for example worn pump or broken impeller)
- low water in the well
- leak in well piping
- running so much water at once in the building that the pump can't catch up
Question: Water pressure surges and pump keeps running
My well is continuing to pump but with surges. Pressure at pump and at pressure valve at house both read 24 to 32 LBS bouncing back and forth. Whole weel system is new and was installed 4th of July weekend. It worked fine all day and then went to take shower and it was next to nothing coming out of faucet. - George
Reply: water surging may mean the pump is short cycling due to a waterlogged pressure tank
George, surging water pressure on a private well and tank system is often due to a water-logged water pressure tank - causing well pump short cycling. See WATER PUMP SHORT CYCLING - article link at Related Topics .
Question: Water-to-air cooling system shut down due to lack of water
Last nite house "water-to-air" cooling system shut down -- safety switch shuts it down when water is not available. Well pump had stopped running.
Replaced well pump pressure switch and pressure guage. Well pump then reached 48 psi and ran continuously at that pressure even though ALL house fixtures and cooling system were shut off !!
The well pump would not reach the 60 psi cut-off point that was preset in the new pressure switch. I then tightened down of the large spring in the pressure switch. With all house water requirements turned off and turning the large spring tighter, the pump would not come above 48 psi and ran continuously. So then I loosened up on the large spring.
Now the pump turns off at about 46 psi. The pump is above ground, single-pipe, jet pump, about 25 years old. Also checked all pipes -- no leaks. This situation really mystifies me. I will appreciate any and all ideas, thiughts, suggestions. I would like to see it cut on around 30-35 and cut off around 50-55 approx. Thanks, Stan
This situation really mystifies me. I will appreciate any and all thoughts, ideas, suggestions - Stan L. Liteborn, email@example.com
Stan, the part of your well pump problem description that reads
"Replaced well pump pressure switch and pressure guage. Well pump then reached 48 psi and ran continuously at that pressure even though ALL house fixtures and cooling system were shut off !!"
Suggests to me that either your well flow rate is inadequate - the water available from the well is insufficient - or there could be a leak in the well piping between the well and the house. Other problerms can look like an inadequate well flow rate, such as a leak in well piping.
Here's present situation: Well pump worked last nite (7/21) and most of today. Late this afternoon, cooling system shut down again. Well pump motor was running, pump itself was too hot to touch and no water was available (opened tank drain faucet and only air came out). I shut off power to well pump, closed main water valve between tank and house and connected up to neighbors well. This has better pressure than I've ever had but not enough volume to run the cooling system (too long a run with hoses from neighbor to me). I will leave it this way till morning and then inspect along pipe route from house to my well, to see if any water is coming out of ground. Higher pressure from neighbors system may thus reveal your suggested .."leak in the well piping between the well and the house". If thats not it, looks like I have either a well or a pump problem --- or both!! How to check well itself for broken/rusted out/cracked pipe? How to check for bad foot valve in well? How to check for well sufficiency / water availability in well. How to check if pump is working, if it will pump water or is broken / worn out? Or is it the best approach to replace 1 item at a time till the problem is solved?? Where to start? Again, I really appreciate your interest and concern to assist with suggestions thus far. Hoping to hear from you with some thoughts about present situation and questions. Thank you so much, Stan
Reply: a hot to touch well pump sounds like the pump is running dry - things to check:
Stan, pump too hot to touch sure sounds like a pump running dry - and maybe a well without water. If you shut off all water into the house and water pressure still drops then that's why I suggested there may be a leaky check valve foot valve or piping. But your description makes us think it's a well problem.
In general it's reasonable to try replacing the less costly, easy to access questionable components first; Also if you end up needing to pull the well line for inspection/repairs, I would always install a new foot valve at that time.
Question: Good water pressure but high electric bills - we think it's the water pump but can't find any leaks
We are having a similar issue with our well.....we have good water pressure at the house and saw an increase in the electric bill.....cant seem to find any leaks....our well is 375 ft deep, and the pump is only 5 years old......any suggestions? - Regina
Reply: check for piping leaks; check the pump current draw ampacity using a clamp-on ammeter
Regina: turn off water into the home and see what happens - if your pump runs anyway then you have a leak between the in-building equipment and the bottom of the piping in the well.
Also, your plumber or well driller can measure the amps current draw of the pump to see if it's damaged or drawing unusual current.
Question: My Goulds jet pump pressure hangs at 39 psi - never reaches the 40 psi cutoff
I have a goulds jet pump that pumps up to 39ibs a stays there . the pump is set to shut off at 40lbs so it stays running .It dose not lose it prime .the water inside the crock well is 2 feed over foot valve .no leaks outside. can you help me ? - Ron
If I have a leak between the jet pump an the bottom of pipe in side the well. Will I lose the prime?
Ron I agree it does not sound like a leak. Try making a small adjustment to the pressure switch cut out pressure to drop it to 38 psi. IF the problem recurs I suspect a clogged sticking pressure control switch sensor.
Question: We lost water pressure and see water leaking into the well pit where the tank is located
We have loss water pressure, & discovered water leaking into pit were we have the bladder for well, what needs to be done? - Barbara
Barbara, start by having a clear idea of where the leak is coming from. Indeed a leak in well piping or at the water tank could result in lower water pressure.
Question: My pump keeps running but the pressure gauge at the water tank sa
I do have some water flow. Pump is a submersiable about 300 ft deep. The contacts are pulled in - I am pulling 7 amps. My bladder tank is about 400 ft. from the pump. The line coming directly from the well is cold. The pressure gauge at the bladder tank is on 0 psi Where do I begin to troubleshoot? - Gary
Gary if the pressure tank is at 0 psi either the tank is not working (intake port blocked by a collapsed tank bladder?) or the well flow rate has deteriorated, or there is a problem with the pump or well piping. Start at the pressure tank.
Question: My pump won't shut off - the pressure builds to 36 psi and hangs there. If I turn the pump off the pressure drops to 30. Pump does not lose prime.
I have a bladder tank and jet pump. The pump will not shut off, the pressure will build up to 36 psi and just stay there, that's with the line going to the house shut off. If I turn the pump off, after a while the pressure will drop to 30 psi, but the pump never loses its prime. Any ideas to fix? - JJ
JJ I've added some diagnostics to the table above, please take a look.
the cold water inside home is heating up why - NJ Payne
We have a Flotec jet pump for our shallow well. After recently running dry (water level must have dropped below the foot valve), the pump continued to run and overheat. This required replacement of several sections of the PVC piping, as it had deformed due to the high temperature. We also installed a new pressure switch (30/50) that has a safety cut-off feature. The pressure tank is set correctly (checked several times, and it is still holding steady at 28 psi). We have primed the pump several times, but it is not operating correctly. The pump kicks on at the correct pressure, but will not turn off. It gets to about 40psi, and stays there.
Alan, it's possible that running your pump at length, dry, damaged the impeller assembly. If that's the case, even though the motor may run, the impeller may simply not be moving water with as much force as previously. You'll need to disassemble the pump, inspect, and replace the impeller parts if that's the problem. Keep us posted, what you learn will help other readers.
Disassembly of the pump as recommended revealed no obvious signs of damage.
Alan, if a well pump is worn or if for another reason the pump is having trouble reaching the cut-off pressure, setting the pressure down to a point that the pump can reach is quite reasonable. But watch out: if the problem recurs you'll need to find and fix the actual problem: with the pump, piping leak, low well water, etc.
Question: My deep well pump won't pump up to 50 psi. Even turning down the cut-out pressure doesn't help.
I have a deepwell pump that wont pump up to 50psi. I have had to turn down the cut-off pressure twice so that the pump would shut off. Does that mean that my pump is going out? - Rodney
Rodney, any of the problems listed in our checklist table above could explain why your pump won't reach full pressure. Typically it's low water supply in the well; sometimes a well piping leak; or see the details listed above.
Question: Shallow well pump won't stop running - after flushing a toilet
I have a shallow well pump that won't stop running after starting when the tank is drawn down by a toilet flush. The pump will start to build pressure but then just stops building and continues to run. If I cycle power to the pump, even if it is just off then on quickly the pump begins to build pressure and will shut off. This only happens when the pump begins to run after a tank draw down from a toilet flush. If any other fixture running causes the tank draw down and the pump to start it builds pressure and shuts off. I am at a loss on where to start.
When the pump never shuts off ONLY after a toilet flush one has to suspect that the toilet keeps running - its tank fill valve may be stuck; Otherwise I'd think the pump and well would eventulally be able to reach cutout pressure once the toilet stopped calling for water.
But a well pump and tank ought to be able to keep up with the water demand from just a toilet tank fill-up alone, so there may be another problme. I''m just guessing but it sounds as if your pump is having trouble reaching the cutoff pressure or has for some reason reduced capacity. When you turn on say a sink faucet the pump probably comes on and runs all the time that you are running water in the sink, but successfully runs up to cutoff pressure and stops when you close the sink faucet.
Question: A few times a month we lose water pressure and it won't return until I shut off power to give the pump a rest
We have a 5 year old well. A few times or more a month we lose water pressure and it won't come back unless I shut the breaker off and give the pump a break. Sometimes the water comes back in an hour and sometimes it takes over night. We have a submerisable pump with a check valve on it in front of it and right before the tank. Before we put the one on at the tank it would drain down. Or at least sound like it. It is 120' well with the pump at 100' and water starts at 30'in the well casing. If I water the plants for 15 minutes or wash 4-5 loads of clothes with a water saver washer and take a bath all in one day (not one right after the other) it is done. I am a x-city person and not sure if I am expecting to much. Our neighbors have great water and no problems with draining their well. Any ideas? - Janice H.
Reply: you are describing a well with a poor recovery rate
Janice you are describing a well with a poor recovery rate or flow rate. Check with your local well driller to ask about hydro-fracking or other steps that might increase the yield of your well.
Question: the plumber dropped our pump into the well, then retrieved it - now we have bad water pressure
Hey, I had to replace submersible pump the company ended up dropping the pump and seven of pipe . Took the several days to get out of 300 ft. hole. Now it supposedly fixed but terrible water pressure. The first had a pump but said was not enough hp so got another one for 200 dollars more. Could they damaged the pump and still used it or went back to the smaller hp to cover damaged pump. I have turned off several fixtures pressure got somewhat better. I am at a loss thanks - James
James, I'm sorry to read about your well pump drop and aggravation. Certainly a pump could be damaged by dropping. I SPECULATE that the damage risk depends on some variables such as the distance the assembly fell through air before impacting water. With no facts, we can't second-guess what the pump installed did afterwards.
I replaced my water pump last year. This year I left the hose pipe running for about 30 min on the grass, and I suddenly had no water pressure and no water. I cut the pump off, but when I cut it back on....the pressure never builds above 28 psi. The badder tank is at 28 psi too. I can not adjust the pump where it will be 2psi more than the tank. Pump is primed, but not pumping water. What is wrong?!? I am a single 29 yo woman in nursing school!! I need water! - Tammy 3/31/12
Tammy, I'm not sure from your question - best bet is to go through the diagnostic steps in the table above, or if you prefer text, see WATER PRESSURE LOSS DIAGNOSIS & REPAIR (article link in the previous question's reply, also found at Related Topics ).
Question: Water pump seems to run continuously but no water comes into the house
I have a system where water is stored in 600 gallon tanks at the basement level of my house. The water is then pumped up to
The tank level also drops then even though no water is coming into the house. I cannot find any obvious leaks
With the water tank level dropping and the pump running continuously, I wonder if you have a leak in the well piping that you didn't see - perhaps deep into the well or under the foundation; Try shutting down the system entirely and watching for a water pressure drop.
Robert, if no water is entering the building and tank pressure drops i suspect a badfoot valve, check valve, or aleak in well piping
Question: how do I clean a clogged, brittle plastic tube between the water pump and pressure switch?
Water pump comes on & off very rapidley
Albert, don't even try to clean that brittle plastic line that transmits water pressure from the pump system to the pressure control switch. If the line is brittle the risk is a break and a building leak or flood. Just turn off the pump, remove the line, take it to your local hardware store to match its size and length, and install a new one.
Question: 3/4HP StaRite well pump won't stop running
I have 3/4 HP Sta Rite Pump that will not stop running. I have installed a new 30 to 50 pressure switch and 0 to 100 PSI gage. No leaks in the system. Pressure tube is clear. Bladder tank is set at 27 psi. Pump will build pressure to 55 PSI and will not stop running with all valves shut. - Gary S 4/22/12
Gary, as you installed a new 30/50 psi switch, and report pump keeps runnng at 55 pzi, i suspect some one or combination of
Question: well pump won't shut off after replacing pressure tank and switch, gurgling in pipes
I have just recentlyreplaced my well expansion tank and pressure switch. Now my deep well pump continues to pump without shutting off. I have checked for leaks in my home and two outbuildings that also share the same well but everything is tight and there are no leaks. I have also shut the valve on the discharge pipe closest to where the water exits the expansion tank. By doing this it allows the pressure to build to approximately 50 lbs at which point the pump does shut off but then it almost immedietly starts losing the pressure and drops to approximately 20lbs at which point the pump restarts. The oddest thing is that while I'm near my expansion tank which is located in my basement I can hear a very loud gurgling noise coming through the plastic pipe that encases the electrical wires that are hooked up to my underground well pump/shaft. The gurgling is happening at almost precisely the same time, coinciding almost exactly with when I'm losing the pressure! - Ken in Jersey 5/10/12
Sounds like a bad check valve or foot valve - is water running backwards from the pressure tank into the well each time the pump shuts off?
Question: well pump runs every 7 minutes if we are running water outside
Pump runs every 7 minutes when valve to outside water is on. Seems OK when I turn the valve off -= but have to keep turning it on when i need to use the hose outside. Can you tell me who to call? Plumber, well drilling company, irrigation company? Please help!!!! - Carolyn Muldowney 7/3/12
I'm confused Carolyn, it seems proper that to run water at an outside hose you'd need to turn water supply on to that fixture. And if you are running water outside continuously, it seems normal that the pump would cycle on at 7 minute intervals. If something is nonetheless wrong with your equpiment, I'd start with a plumber.
Question: well pump with relief valve in the well pipe line - relief valve is spilling
i have a well pump with a relief valve in the line just outside the well pipe. when i run water in the house the relief valve open and dumps some water. does this indicate i have a tank problem? - Bob S 7/7/12
Question: Jet Pump keeps kicing on for 1-4 seconds every 30 seconds
I'm having problems with my Jet Pump, it continually kicks on and off for 1-4 seconds every 30 seconds or so and I am wondering what the cause of this may be. I have no water turned on and there are no leaks I have been able to detect. I have a shallow well, and the pressure seems fine at the tank.
If you have no water running in the building AND can actually turn off water into the building and the pump keeps cycling on and off then it sounds as if there is either a bad foot valve or check valve or a leak in well piping. I'm assuming there are no visible leaks above ground.
That very short well pump on-time is sometines traced to a clogged water filter or a collapsed bladder in a water pressure tank.
Question: Deep well, Goulds 3HP pump, just a water trickle in the home
I have a 750 ft deep well, goulds 3 HP pump...well and pressure tank together 100 feet below home site. Only have a trickle inside of home. I have about 45 psi at well...turn on one faucet it drops to zero. pump will run all the time if allowed. Have 30-50 pressure switch. Diagnosed as bad impeller...must pull well pump. NO leaks detected. Pulling 12.5 amps...motor sounds smooth. Technician said I should have about 80 # pressure on guage with the 3 HP at 750 feet. Do you agree with his diagnosis? Thank you so much. - Anon 7/31/12
Yes, Anon. I agree that you ought to see good pressure in the house; IF there are no well pipe leaks and the system can't develop pressure it makes sense to check the pump for damage; first you might want to check the wiring and voltage levels.
Question: well pump hesitates for a minute before coming on
My well pump would hesitate for about a miniute before coming on, while running water. I replaced the pressure switch and now the pump will not shut off. It builds up to 90 to 100 psi , but keeps running. I put a second switch on and it does the same thing. Both pressure
Larry quite often a delay like that is due to clogging at the pressure sensing port of the pressure control switch, or the tube that feeds it. If you replaced the switch but left a clogged pressure line in place the problem would remain.
Question: well pump runs continuously after recent storm, no pressure, but water comes out of the relief valve
Have a well pump that began to run continuously after a recent storm and no pressure builds in the system BUT an apparent pressure relief valve on the pump body emits a high pressure stream of water. Doesn't seem like a loss of prime with the high pressure stream but the system pressure is zero while all this is going on. Any thoughts? - John 8/1/12
John, our best guesses for a pump that won't stop are in the article above, but your comment about the problem showingup after a storm suggest that a pump control or switch or wire may have been damaged by a power surge or lightning. The opening of the pressure relief valve is consistent with a pump that is not shutting off and is overpressurizing the system.
Question: well pump runs continuously, contact points in the switch are burned
This past Wednesday my Mom noticed the pump contiuously running. Sunday when i get there I notied the contacts in the pressure switch looked burnt. i replaced the pressure switch but the pump still won't shut off.
Question: replaced pump and parts 3 years ago but now pump now won't shut off
I replaced my jet pump, foot valve and all lines from jet pump down to foot valve 3 years ago. Well maybe 50' deep and the pump is a 1/3 hp pump, that's what was there originally. After replacing all this the pressure would not build above 25psi and sit there and the pump ran continuously. after a while of adjusting the pressure switch I managed to get the pump to shut off at 25psi. At this point the pump began to work well, cutting on at almost 0psi and cutting off @ 25psi. This was not perfect but it did the job.
This past weekend the pump stopped cutting off automatically. With adjustment I got it to stop running but then it wouldn't turn on just on-off-on-off.
I replaced the pressure switch and same thing. Sometimes when I shut off the pump, manually, the pressure would instantly drop to 0psi, sometimes it will hold @ 25psi, and still other times it will drop to 0psi and then over a couple of seconds build to 20-25psi, while pump is shut off. I shut off the valve between the pressure tank and the rest of the house and the pressure did not drop, over 5-10 min. Please help, this pump not automatically shutting off is driving me crazy. Sorry for the long post. - Mike 8/15/12
Intermittent occurrence of sudden dropping pressure suggests a sticky check valve or foot valve.
Question: City water and Goulds pressure booster pump - pump cycles all the time
We live on a hillside. I have city water that is sent through a Goulds V250 tank and a 1.5 HP pump to boost the pressure before it heads into the house. The pump began cycling continually and drastically spiked our electric bill. I replaced the switch and discovered the neck was corroded and I assumed this was not allowing the water pressure to signal it to cycle off. After replacing the switch, it is still cycling continuously. None of the suggestions above seem to fit. Any thoughts? Thank you for your time. - Oscar 8/31/12
Oscar, did you replace the tubing that conducts pressure to the pressure control switch? It may be clogged.
Question: Pump keeps running and won't get above 25 psi
We have a shallow well double hose system but total hose reaches approximately 65 feet from well bottom to pump. Our pump keeps running and will only reach 25 psi. The pressure does not drop. We have tried turning off the valve where the water comes into the house, still no pressure loss. Have not touched the pressure control switch. we have had the pipes out and have not noticed any significant leakage.Great water pressure coming out of the tap. What do you recommend further. thanks joe - Anon 9/2/12
If you have "great water pressure" but the pump gauge only says 25 psi (and pump keeps running) perhaps both the pressure gauge and the pump pressure control switch sensors are clogged with rust or debris.
Question: shallow well pump won't shut off, I turned it off manually, then it lost prime
i have a shallow well pump that will not shot off so i turned the power off and the next morning i had to prime it and it still will not shut off - Dallas 9/22/12
Dallas, I'd start by going through the "well pump won't shut off" diagnostic suggestions in the article above - as that list is our best advice.
IF the pump was primed and running and was delivering water BUT then lost prime after you turned it off manually, I suspect a leak in the well piping or a leaky check valve or foot valve.
Question: water pump suddenly can't maintain water pressure
My water pump suddenly stopped keeping water pressure in our cottage.
As an update, it seems we've had air in our lines. Some new connections we made this summer putting in a new pump and pressure tank and foot valve were ridiculously loose when we double-checked them yesterday. It must be that they were installed on a hot day, and now it is much cooler, getting close to freezing at night...I have no idea if that is possible, but the connections were finger-loose surprisingly.
At the risk of posting too many messages, we're so lost at figuring this out, I'm going to risk it. :)
Sandra, I'd go step by step through the table above.
Your statement "The pump stays mostly primed. The pressure tank does not seem to be getting any water at all. " is confusing. If the pump is not staying COMPLETELY primed then there may be a leak in the water supply piping or foot valve; or the pump itself may be damaged and is unable to deliver water.
Question: Sears horizontal water tank from 1950s and Sears Air Volume Control; after a running toilet problme the well pump now runs too long
We have a Sears horizontal tank and fittings (probabaly installed in the late 1950s. We also have a Sears Air Volume Control. Some months ago we have come home after being away for several weeks to find the toilet had been running constantly because the ball cock malfuctioned, this led to the water pump running constantly. Now the water pump will run for one half to one quarter of an hour or until I manually shut it off. Some times to restart sometimes not.Im not very handy so when I have it serviced what should I beware of by way of someone taking advantage of me ? - Al 10/26/12
Unfortunately Al, when a water pump runs for a very long time continuously, for days or longer, and if the problem is not that you ran the well dry, it's possible that the pump itself has become damaged. I'd pull the pump and inspect for damage to the bearings or impeller assembly.
Question: jacuzzi pump and pressure switch not turning off the pump
I have a jet pump(jacuzzi) pressure switch is 20-40. Thought the switch was bad,so we replaced it. Now the pump just wants to run,will jump up to 55-60.have good water pressure,just wont shut off.have turned it ,it is on factory settings,even with the power off,it is holding at times to 70psi. but if we turn the power on, the pump will not shut off.we do have a bladder tank,it has the recommended pressure of 30 in it. any ideas Y.R. 10/26/12
