If you are experiencing no water from the well, there can be many low water pressure causes, including a failing well pump, stuck check valve, partially closed or bad gate/ball valve and leaking/failing pressure tank. In some cases, iron bacteria clog up the pipe nipple leading to the pressure switch causing the pressure switch to sense pressure incorrectly.
If the well water tests high in iron bacteria, your pump and/or well screen may become clogged with iron bacteria. Having the well cleaned with a special solution designed to remove iron bacteria, slime and scale can often restore the well to a better condition.
The pressure is often set to turn on at 30 PSI and off at 50 PSI in some well systems. For today’s homes and appliances, this pressure can be too low. Often it is possible to raise the pressure, so the pump turns on at 40 to 50 PSI and off at 60 to 70 PSI, providing an adequate water pressure in the home.
The pressure switch can often be adjusted to accommodate this higher pressure, assuming the well pump and well can operate without difficulty at the higher pressure. Air pressure inside the pressure tank must be adjusted if the pressure switch is adjusted.
