today we discovered that the pressure in the tank will not get above
20lbs of pressure. one flush and there's not enough pressure to fill a glass of water. i closed the system at the main valve past the pressure tank and killed the power to the pump-the gage stayed at 20lbs for over 15 minutes so i don't think i have a leak anywhere underground, but the pump continues to run even with the the valve past the pressure tank is closed and the gage stays at 20lbs. i tried to adjust the pressure switch to see if i could stop the pump that way(using a electic test meter on the switch--but had no luck) the well should be fine we are not in a dry area and have had plenty of rain this springis my pump going???
