Hello everyone, I am new here. Looking forward to discussions and hopefully getting help. My water pump will not shut off. I will forgo all the particulars. Farm house well is shallow, been in use for about 60 years, with piston pump or new jet pump. PROBLEM IS: it will not shut off when high pressure is reached. I have put in 2 new pressure switches and problem persists. If I shut the pump off via disconnect, and turn it back on, it is all good. That is, it will come on at lower pressure setting but not shut off. I suspect that the small 1/4 copper tube from pressure switch to "bell housing" of pump is clogged with sediment on pump side.
Can this be cleaned from the "tube" side with out disassembly of pump? Or is there something else I have missed or need to check into? Current pump is a Gould. It works fine if cut on and off manually. As I have a 200 gal pressure tanks, I can live with this for a while. Any help greatly appreciated

A picture would be great if possible.

I assume the pressure climbs past the pump cut-off pressure which you can see on the gauge?

How long is the tube to the switch?....is it straight?.....compression fittings at both ends?

Ideally you should remove the tube completely and see if it's blocked.

You might be able to push a length of stiff wire through it to clear any debris.

Remember to open a tap and depressurize the system prior to removing the tube.

With the tube removed momentarily start the pump to make sure the fitting is not blocked as well.

I would install a new fitting and line connecting to your pressure switch. I occasionally find them clogged or rusted shut. In many cases the pump just reacts slow. Over and undershooting it's pressure settings since there is only a tiny pinhole remaining inside the pipe to convey the water pressure to the switch.

 

1/4" line OK but the fitting in the pump for the 1/4" line was solidly plugged.
25 years of slit and a little rust. Cleaned out, re-installed and it has been working OK for a couple days now. Thanks to all. It is ALWAYS nice to have someone to talk this type of thing through with. thanks again
