A well pump pressure switch is a device that automatically turns on and off a well pump to maintain water pressure in a home or other building. The switch is typically installed in the pressure tank, which is connected to the well pump. When the water pressure in the tank drops below a certain level, the switch turns on the pump, which pumps water into the tank until the pressure reaches a predetermined level. The switch then turns off the pump.
Well pump pressure switches are an important part of any well water system. They ensure that there is always adequate water pressure for household use, and they protect the pump from damage caused by running dry. Pressure switches are relatively simple devices, but they are essential for the proper operation of a well water system.
