Pulling my hair out we have a rapid clicking in the pressure switch at the water tank It causes the lights downstairs to blink as well.. we have pulled the well out .. we had to replace the pump not long ago.. we checked all the water lines for leaks tightened all the connections...

Troubleshooting without a new pressure switch.. we bought a new valve.. its clicking and the lights blink rapidly..b we have a 2040 switch but it only runs up to 30 before it cuts off..

we have done everything I could read other than replace the tank but it seems the tank is holding pressure..

now we have a pulsating of water throughout house.. as if it is surging... please help I've spent so much money I can't afford a plumber at this point again

The faucets in our home, including kitchen sink, shower and bathroom sinks all kicks water out rapidly like kicks on and then goes really low and back on within a second and it keeps doing it. We have a wellsaver pump tank and when the water pulses like that, the gauge on the pump tank kicks from 60 psi to 30 back to 60 to 40 and so on.. can someone please help me figure out whats going on here?

Perhaps you have a large water pressure tank with a good air charge that is delivering water but at modest pressure until enough water is drawn that the pump is turned on.

On 2019-01-12 by Loo Chiew Geok

When we open the tap, the water pressure is low, only after 10 to 15 minutes then the water pressure works n volume of water bigger. May I know what is the problem. Thank you

On 2018-11-26 by (mod) - pressure tank is making a continuous clicking noise

Lexie

If your pressure control switch is clicking fairly rapidly on and off when you are running water I would suspect that you have a submersible pump and the pump and control or short cycling. That's typically due to loss of the air charge in the pressure tank. See this Diagnostic and repair article

On 2018-07-09 by (mod) - signs of a leaky foot valve

Tracy,

that sounds to me like a leaky check valve or foot valve

On 2018-07-08 by Tracy

100ft deep well - submersable 1/2hp pump - 20/40 pressure switch.

When our water stopped running originally, I checked the pressure switch{ 20-40) and found that earth worm had commited suicide across the contacts.

Also noticed that the presure guage had a small amount rust inside and out. I immediately replaced both, and nothing. I came upon your site while researching the possible problem.

Following your various diagnosis and FAQ's, I have repaired a couple leaky pipes, checked for clogged tubes and tightened the fixture on the bottom of my pressure tank (which had to be pulled out of the mud btw) and had to add air to bring it up to the 18psi cut-off.

I checked and made sure that my wiring was correcct and that the pump (submersible) was recieving power, How this system was ever working before I'll never know. Still nothing, which lead to pulling the pump .

Had to buy a new one but chose a 3/4hp instead and changed switch to a 30-50. after these were installed, I searched and found a small leak right outside the well casing.

Nothing... searched further and needed to readjust the pitless valve because a friend helped install the pump and didn't have the valve lined up. All this being said, when I try to get things going here's what happens.

To get any pressure at all I have to back fill water from an outside source throughan outside spout.

This brings tank Pressure up to the cut-off 28psi but no higher. As soon as I turn off the outside spout, and open a faucet in the house, pressure will start to fall thus making the switch come on.

The switch contacts will stay together while all pressure will slowly lower until it reaches the low pressure protection pressure of 20psi, the the switch kicks off. I have checked and found that when the switch truns on, the wiring at the well to the pump will jump.

I have even used a multi meter to make sure that the pump was still getting power. I'm ready to give up. What am I missing?

On 2018-06-30 by Bob

Your description is about right. The pump is only for the sprinkler systems.

When the water is running through the system the water psi is about 48. When the sprinkler control turns off the system, the pressure rises quickly to 70psi and the relay opens.

The pressure slowly drops to 30psi and the cycle starts again. It all stops when I shut off the water value that lets water out to the sprinkler system.

So, you are probably right that there is a water leak somewhere in the system after the valve which lets the water out to the system.

On 2018-06-30 by (mod) -

Bob

I am (to be candid) a bit confused myself - (trying to constrain this answer to pump and pressure controls and tanks nevertheless)

Is this right:

You're running water in a sprinkler system (often that high level of usage can exhaust a well - is this well ONLY for the sprinkler system?)

When the sprinkler sys. is running the relay is quiet - that's because the pump is probably running continuously

When the sprinkler stops the pump and relay expect to keep running long enough to reach the pressure control CUT_OUT pressure (70 psi on your system).

Then the pump will stop and IF NO WATER IS BEING USED the system will just sit there quietly.

But your system shows a pressure drop down to 30 psi - the pump control's CUT IN prssure and the pump turns back on.

When we see this there is
- water running somewhere in the building - a leaky pipe, a running toilet
or
- water leaking out of a leak in well piping
- or a leaky check valve or foot valve between the pump and the bottom of water piping (or submersible pump) in the well.

I suspect you've got a bad foot valve or check valve

See WATER PUMP INTERMITTENT CYCLING https://inspectapedia.com/water/Intermittent-Water-Pump-Cycling.php

to confirm and fix this diagnostic guess from my spot here in Mexico.

On 2018-06-30 by Bob

I meant to say dropping from 70psi down to about 30psi

When the pump is pumping water for my sprinker system while it is in action, the SquareD relay box is quiet. But once the sprinkler is stopped, the relay in the SquareD box enages/disengages about every 15 seconds.

If I shut off the water flowing into the Well Trol Pressure tank the relay stops its 15 second cycle. There is water pressure gage showing pressure rising to about 70psi then dropping to 0 when the relay engages. It does this over and over as long as well pump water is made available to the system. The Well Trol pressure tank has 28psi of pressure. Is this not enough ?

My well is making a clicking sound every few seconds. What does that mean? There are no other noises and nothing else is going on, including water use.

On 2018-01-14 by (mod) -

If all electrical power to the building is off then I would not expect the well pump to be running and I would not expect any of its components, electrical or mechanical, to be a source of noise.

I speculate that there is a leaky foot valve or check valve (or a leaky well pipe) and that maybe you're hearing water flowing backwards into the well from the pressure tank when the pump is off.

In my OPINION it sounds remarkably strange to claim that you should drill a new well and install all new well equipment if the actual problem is a bad foot valve.

You ought to be able to pull well piping, replace foot valve, replace any questionable piping, and even replace a pump and pressure tank for a fraction of the cost of drilling a new well, and that's *before* eating the risk that after $8200. of your well drilling quote you haven't reached an adequate water flow and have to keep drilling deeper, for a deeper dig into your pockets.

For a well expert to tell you it's not worth replacing a bad foot valve (the part is typically less than $20. U.S. there must be a mystery here that we don't understand.

I have a constant straining fluctuating humming noise in the house, originating from the well and traveling through the pipes.

The noise is on even with no power to the house.

While the pump is running, the noise ceases. There is no noise while top pressure of 60 psi is maintained.

After a very short time the pressure start drolli g slowly, and when it goes under 40, the noise re-starts. The pressure drops slower if I isolate the house from the water tank. I do

have water, there was no need to prime the pump. It is a Gould's three stage jet pump on a 62 years old well that is 365 feet deep.

I was told it is a bad foot valve or leaky pipes inside of the well - not worthy to attempt the repair.

Having a new well drilled for $8,200.

Thoughts?

I was wondering are there any tricks to get the foot valve working again - if it is a clog ...

On 2018-01-07 by (mod) -

It's normal to hear some noise as water fills a pressure tank.

Humming from any electrical control box often means that a relay switch or low voltage transformer is acting up and may be near end of life.

I am new to having a well... after the freeze these last couple of days, I finally turned on the breaker to the well... no water was shooting out of the relief valve, BUT the switch control box started humming...

It's normal to hear a click when a relay opens or closes.

If your water pump is submerged in the well (so you can't hear the pump motor) you may just hear the relay clicks

If the relay clicks repeatedly there are several possible causes such as

- burned points

- valve closed between pump and tank or

- dirty water filter downstream from pump

- waterlogged pressure tank

I REPLACE THE POINTS ON THE PUMP AN ITS MAKING A CLICK CLICK NOISE WHEN I TURN THE PUMP ON

On 2017-07-16 by john

I have replaced my well pressure switch, which is attached to a bladder tank in my basement, due to severe arcing.

However the new one (30-50 psi) is still arcing when the contacts open and close. I am in the process of installing a propane heater within 10 feet of this pressure switch, and am concerned. I am thinking I could replace the capaciter? Is this normal operation for the pressure switch to arc? Any thoughts are appreciated.

My 1/2 HP deep well control box is beeping one beep per minute continuously since a power outage a few days ago. I replaced the control box but the beeping is still occurring. The water flow and pressure in the house does not seem to have diminished whatsoever, and the holding tank has 38 psi as it usually does. What are potential reasons for this?

On 2017-07-13 by (mod) -

Rapid clicking can be a burned switch or a waterlogged pressure tank - check the air charge in your water tank

Replaced residential well pressure tank, after installation, pressure switch started clicking rapidly when pump turns on. Contacts looked worn so replaced pressure switch. New pressure switch is also clicking on/off, on/off rapidly 2-4 times each time pump turns on.

What could be the cause, the new pressure tank?

On 2017-03-21 by (mod) -

Strange, I'm not sure what's clicking. Perhaps water running through piping or controls?

If the pressure drops when no water is being run then there's a leak or a bad check valve or foot valve.

On 2017-01-14 by (mod) - buzzing in a control box

Justin:

Usually buzzing in a control box like the one you describe by Webtrol means that a low voltage transformer or more likely a relay switch is failing or has failed. I'd replace the control or at the least, if possible the buzzing relay. Watch out for electrocution - death by shock.

On 2017-01-14 by Justin

Water stopped coming through the faucet the other day.

Notice the Webtrol control box for the well pump has a buzzing sound that comes about every15-30 seconds then stops. The control switch (not the control box) on what i believe to be the bladder looks somewhat burned out, but not really sure how to test if its still working or not.

With the cold weather i had been letting the watter run a slow drip on the faucets, i am gessing I burnt out the control switch by doing this? My guess about the buzz from the control box is its just telling me something isnt working properly in the system.

I am a DIY as much as possible but havent really looked into replacing a control switch yet and not sure if that is where i should start. Unfortunately the house was a forclosure and no back story on the well system.

Really loud buzzing or humming sound coming from the water pump, the noise is continuous for past 6 hours . What can I do?

On 2016-10-03 by Samuel - system makes a loud thudding noise

My well motor has a black knob to change from 115 to 230. I tried to change it to 230 and heard a click.

Then when we turned the breaker ON, it sparked and burned that part where black knob is. Is my well burned now? I bought it 2 months ago. Installed it myself but my neighbor said is supposed to be set at 230 not 115.

I have a well pump filling a pressure tank for my geothermal system.

When cutting in at 20 psi, the system makes a loud thudding noise which seems to be much louder than it ever was in the past (I have had the system for about 9 years). About 5 years ago, we had to replace the pressure switch when the contacts seemed to have burned. What could be the cause of this noise? Is it a water hammer?

On 2016-09-06 by robert - water pump clicks like it wants to come on but then pump just hums.

My water pump clicks like it wants to come on but then pump just hums. I changes out the pressure switch and thought that was it but still same thing. When pump tries to come on, if I hit the end of pump really hard with screwdriver and something similar it usually comes on but only works for a little while and then goes off again. Could it be capacitor going bad or something else?
thanks

Generally no, except that if the pump was running when you stopped using water you might hear the switch click once when the cut-off pressure is reached.

If your switch is turning on and off for no apparent reason search InspectApedia.com for PUMP RUNS INTERMITTENTLY or PUMP RUNS FOR NO REASON to read diagnostic suggestions.

Should the water pressure control switch click when water is not in use?

On 2016-07-25 by (mod)

A

Perhaps your new switch includes a pump protection circuit. If so, the switch will turn off the pump if it finds the pump running dry;

Finding deposits on the points, unless by some fluke the switch was defective, is not going to be fixed by cleaning the points: once you scrape or sand the contacts in any electrical relay, the small natural arcing that leaves some burned material on the contact surfaces will actually increase because you've removed the original protective plating on the contacts.

I'd instead look for causes of short cycling (search InspectApedia for PUMP SHORT CYCLING CAUSE if your pump has been turning on and off to rapidly
or
I'd check for debris in the water supply that might clog either the pressure sensor port on the pump pressure control switch or that might clog the tube that conducts water pressure to the pump. More details are below in my reply to Ozarks.

We had a new pump and pressure tank put in two weeks ago. The new switch on the pump keeps stopping. They have come and cleaned the circuit points in the switch and it will run about two weeks and quits again. They are finding the points in the switch covered with some type of coating and it has to be cleaned again. What could be causing this? They are ready to put in another new switch if the cleaning job they did this time does not work.

On 2016-06-20 22:16:03.248947 by (mod)

I'm not sure, Ozarks,

Often a very rapid on-off cycling of the pump or pump control switch - less than a second - is due to very rapid rise to cut-off pressure. I think this happens wehn

- a valve out of the pressure tank is closed

- a filter cartridge is very dirty and blocking water flow out of the system

- a pressure tank is waterlogged

- sometimes a pressure control switch is defective

On 2016-04-21 by (mod) - noise has recently developed in the vicinity of the tank

I wonder if the pump is having trouble reaching the cutoff pressure or if there is air in the system piping or water source. If your filter cartridge is see-through you might look for bubbling.

On 2016-04-21 by Bill

A year after upgrading the well tank pressure switch (from 30-50 to 40-60 w/ LPCO) and the pressure tank itself (from 20 to 32 gallons), noise has recently developed in the vicinity of the tank T. Cut-in at 20 psi and cut-out at 60 psi continues. After cut-in, noise develops at 45 psi, continues, and then subsides at 55 psi.

The noise is a moderately frequent rattle/knock very similar to the noise we'd get as kids when we attached playing cards to the fender strut on our bicycles. Until the noise starts, the fill rate seems about normal which used to result is a replenish cycle of about 45 seconds. Now, once the noise starts the fill rate seems reduced and the replenish cycle is about 2 minutes.

The tank seems to fill normally, as (by hand touch) the lower half is cold from the ground water temperature, and the upper half is warmer from the ambient room temperature. The well yield is unknown, but in the 22 years we've occupied our premises we've never exhausted the water supply. (Nominal load: two people, dishwasher, clothes washer, three bathrooms/toilets, two showers.)

Sediment collection (usually small, fine grit) at the whole-house filter continues at a minor level. The 1-micron carbon filter requires changing every 1.5 - 2 months. From these symptoms is seems the submersible pump may be failing. It's a half-horse Gould located at 75 feet in a 90 foot well. It was installed, new, in 1983.

Any comments or suggestions, please? Thanks!

On 2016-03-01 by Gary

After running no problems for several years, in july 2014 water pressure dropped to zero before pump kicked in. I replaced the Square D pressure switch (40-60) and life was good again. Same thing happened last week. I replaced the switch and could not get the switch to cut out. I adjusted the range switch to no avail.

Suspecting a bad switch, I went back to Menards and purchased a replacement switch. Same problems--would not cut out--I turned power off at 70 PSI. Could not adjust to make any difference.

Thinking the whoe batch was defective, I purchased a 30-50 switch from Lowes this time. After backing off the range screw 9 turns CCW, I got a cut out at 30 PSI. I adjust 3T CW & got cut out at 39 PSI. I adjusted 3 more T CW and switch would NOT cut out but made a surging sound.

Through all these trials, switch wouold not cut in--I had to use screwdriver to trip lever back to cut-in position.
I called SquareD tech support & he said my pressure tank pressure was off. I checked & it was the same as always: 38 PSI.

Any suggestions?

On 2016-02-29 by (mod)

I'm not sure what's happening, Huey. Are you sure the noise is coming from the pump itself and not building piping? Search InspectApedia.com for WATER HAMMER NOISE to read details.

If you are sure the noise is at the pump motor look for

- loose motor mounts

- a failing impeller assembly

- loose piping near the pump

- something else I've not thought of

On 2016-02-22 by (mod)

Find and fix the source of vibration: a loose pump mount, loose pipe, failing pump bearing. You might also need vibration / sound isolating plumbing pipe mounts but I'd prefer to find and fix the cause than to treat the symptom.

Norris:

There are multiple causes of pump noise. A very common one is running the pump dry - having lost its prime.

IN that condition the water pump sounds more noisy than usual and the sound level will drop when the pump impeller chamber is re-primed (water full). Other noises may be due to a failing bearing, loose connections, loose pump mount, air in the water supply.

Hi
Please help I have no water!!!! Here is the whole story. I bought a trailer on private property. When the water would run the lights would dim and pressure would change from high to low.

Then the lights started flickering and water was pulseing on Christmas I lost water so I took the well cap off pulled the pressure switch noticed the ground was a bit soggy but it had rained.anyway switch as totally burned up and fell apart in my hands.

I replaced it and water was back on and more normal than ever problem solved right? WRONG!

Lost water today go out to take well head off and water was coming by out of the ground like jed just stru k oil in Beverly hillbillies. So I take the cap off reset the switch it looks like new it starts clicking and will not stop no matter what adjustment I make.

To answer your next question is bad Blatter in pressure tank right?

Well mine is in the ground between the well and the house. I am frustrated and don't know what else to do.

Reply:

Andy I can't tell if the problem is that the pressure switch has failed or if the pump motor has failed and the switch is buzzing trying to turn on the pump.

And if this is a deep well with a submersible pump in the well there MA be a second relay that actually turns on the pump.

I would turn the system off -electrical switch - and get some help from an electrician or plumber familiar with pumps and controls. Keep us posted.

Question: chattering on well tank piping

Why is the piping on my well tank chattering while filling. I have an 850 ft. deep well. I don't have any problem with pressure.

Reply:

Anon: I don't know. Often flowing water will cause water piping to move around from pump vibration, surging pressures or (not so good) even air in the lines; securing the piping, perhaps using fittings intended to avoid conducting noise, may be a first step.

I just installed a new pressure tank and switch. The switch is a pumptrol 40-60. The switch arcs once it reaches the 60psi cutoff pressure. It does not chatter or bounce,it just sparks as contacts separate. Is this normal?

Reply: Arcing at the pressure control switch

I'd check for dirt on contacts (don't file or sand them) - with POWER OFF -and also check voltage as well as for loose connections. If all of those are clean and secure you may be seeing a normal arc.

If it's large, bright, I suspect a bad switch. Call the manufacturer (Schneider Electric) to ask if they want you to replace the device. Keep us posted.
