The pressure switch tells the pump when to start and when to stop. It is a small part, but when it fails the whole system can stop working or run without shutting off.
Pressure switch replacement is often a straightforward repair that restores normal operation, as long as the cause of the failure is understood and addressed at the same time.
Signs the Pressure Switch Is Failing
- The pump will not turn on even with power available
- The pump keeps running and will not shut off
- Visible pitting or burning on the switch contacts
- Chattering or buzzing from the switch
- Pressure readings that no longer match the switch settings

Replacing the Switch the Right Way
Before replacing a switch, we check why it failed. A waterlogged tank or a clogged pressure sensing tube can wear out a new switch quickly if left unaddressed.
The new switch is installed with secure wiring connections and set to pressure levels that suit your system. The tank air charge is then adjusted so the switch and tank work together.
