    A little background - I'm buying a foreclosure home with a well. The house was "winterized" to keep pipes from freezing. I'm assuming this just means that the pipes were drained and water was turned off. Yesterday I opened all the water valves, turned the power on, and turned the power to the well on. The well immediately started pumping water, faucets, toilets, everything running great. However, when I went under the crawlspace to check the hotwater heater I noticed that the pressure release valve was open and water was draining from the hotwater heater. I immediately looked at the pressure tank for the well and the PSI was around 120+.

    Shouldn't the pressure switch have cut the pump off? By the way, the pressure switch is a square D 20/40. Should I just try adjusting the cut out pressure on the pressure switch? I can't imagine that the previous owner would have had it set that high.

    Fixed my own problem

    Looks like no one had any suggestions on this one...thats OK though because at long last I figured it out.

    I replaced the pressure switch to no avail - as as soon as I turned the pump back on the pressure would immediately climb nonstop over 100psi. I guessed correctly that the switch itself wasn't getting pressure from the nipple. When I removed the nipple it was almost completely sealed with mineral deposits. I replaced the nipple and everything works great.

    Good thing you had a water heater. You should add a relief valve at the switch area also. If you have a lot of junk in the water you might add a "Y" type screen valve at the pressure switch to reduce such issues.
