I have a Goulds JPlus water pump inside my home. Last night, my wife and I heard it going on and off repeatedly when we went to bed. I have two shallow wells hooked up to it, so I switched wells even though I didn't believe the one I was on was dry (it was supplying H2O fine).Still no luck, so I turned it off at the breaker and shut off the valve between the tank and pressure switch. Today, the pump pressure gets to between 50 and 60, then goes off. It then loses pressure v ery quickly (approx 10-20 seconds) and goes back on when the pump switch hits the lower threshold. It sounds like the water is running back through the pump and out of the house when it goes off unless I turn the shut off valve I spoke of earlier. I changed the pressure switch and no difference.I can, however, turn it on and shower, flush, etc. I just then have to go down and turn the pump back off.Any help would be greatly appreciated!
Do you have an air tank hooked to the pump? That is what usually holds pressure while the pump is off. It may have a leak in the bladder.
If there is space try to hit the head of the bolt with a hammer, the shock from the hammer blow will help you to loosen the bolt. Failing that the next thing to try is an allen key socket, with this you can use a long strong arm to apply extra torque to the bolt. Be carefully not to open up the head of the bolt as this can be a major pain. If you still cannot get it out then if the water pump is to be replaced try to get an angle grinder on the bolt to cut its head off. Once the head is off and the pump is out you can use a stud extractor of a good vice grip to remove the stub of bolt left over.
Tommy is correct in saying that a proper air bubble in the top of the water storage tank is needed to provide a slowly declining pressure on the system as water is withdrawn. But if no water is being withdrawn inside the house then a check valve preventing a backflow through the pump discharge and allowing loss of water in the pipelines to the individual wells is leaking. It needs to be replaced.
