Have a house in NH with an artesian well for water supply. Cold water well pressure tank was replaced about 10-12 years ago but not the pipes around it. Recently I had to do some work on an upstairs faucet and shut off main valve from pressure tank to the rest of the house. When I turned the valve back on, I noticed water coming out of pressure relief valve. Over time the water slowed to a slow drip. Now I notice that every so often, the drip turns into a "drizzle" and water comes out at a pretty good clip (not sure about water usage at that exact time). The pressure gauge shows 45 PSI and the relief valve lists it's rating at 75 PSI. Originally thought pressure valve may be old or clogged with sand or debris, but I have noticed the pressure gauge needle not moving at all from 45 PSI; doesn't seem to fluctuate, is this normal? I am planning on replacing the pressure gauge and then the relief valve if the pressure is fine. What could be raising the pressure in the tank if the relief valve is not the culprit and it is doing it's job? There is some kind of "Pumptrol" mechanism between the pressure gauge and relief valve. Is this the pressure switch and could this be the problem? I am trying to repair this myself but am concerned about the whole water, electricity, pressure thing. Looks like if I shut the breaker, and drain the tank everything seems straightforward except maybe the pressure switch. Any ideas. The tank is a Flexcon WR120S. It is about 4feet high and 16 inches in diameter. I couldn't find how many gallons it holds. Thanks.
