Bad gauge.
If the pump shuts off it can not build up any more pressure.

water pressure problem


Gonna need some more info, generally there aren't many pressure switches, outside wells and boilers, in a domestic water system.

You need to describe very precisely what happens. For example, why do you think the pressure switch shuts off? How do you know the pressure gets to 80-90 psi? As previously noted, if the well is off, it is impossible for pressure to build further, so possibly you are being fooled into thinking the pressure switch is off, when it is still calling for the pump to run.

How old is the gauge?
If it is more than a year or so old it could be bad, and if the water quality has hardness and iron that will have a gauge go bad even faster unless you have spent about 100 for an oil filled gauge.

Daniel,
I stand next to the pressure tank, pressure switch and watch the pressure guage when the switch kicks on. I hear the switch kick off at approx 50lbs on the guage. After the switch kicks off the guage reading continues to rise to anywhere between 80-90psi. The pressure guage is brand new, put in 3 days ago. I have also gone outside after the switch kicks off and listened in the well housing to see if the pump is still running and I dont hear it running.

By the time you hear the switch kick off and run outside to listen to the pump the pump could have continued to run, jacking up the pressure, unless you are the road runner.

This may sound weird, but why don't you have someone stand by the well pump breaker, and as soon as the new gauge hits 50 tell them to kill the breaker, then tell us if the pressure continues to rise.

I don't belive the pump will go to 80-90lbs psi you didn't say what HP the pump is, i have 1 1/2 HP pump and i turn on the bleed down spicket in a hose to run out side the pump will pump up like 65 or so pond's of preasure that is the most that pump will do . I belive i would get another gage , they make one that goes on to a spicket turn that on and have some one watch that one i bet it doesn't go 80-90lbs psi which is should do if that is the water preasure.

The pressure can not continue to build unless the pump is still running. After you hear the switch kick out give it a rap with the handle of a screw driver. Sounds like the contacts are sticking.
