We have 2 different kinds of pressure switches, PA-103 and PA-104. They are mainly used for self-priming pumps.
Pressure gauges are an important indicator of whether a system or component is operating correctly. Well pump pressure gauges is a useful tool in monitoring a properly functioning water system. The ability to see at a glance the pressure of the well pump system can aid in any water flow problems. Pressure gauges generally require little to no maintenance, other than periodic calibration. The pressure gauge is normally mounted on the pressure tank just above the well water pump pressure control switch.
