A well pressure switch is one of the components that make up a well water system. It is responsible for controlling the operation of the well pump based on the water pressure in the system. When a well pressure switch does not work properly, you may experience a lack of water or very low water pressure in your home. Moreover, a malfunctioning pressure switch can cause the well pump to cycle on and off rapidly or at irregular intervals.
Thankfully, there are simple steps you can follow to test a malfunctioning well pressure switch. You don’t have to be an experienced plumber to test a well pressure switch, but if you’d like assistance from a professional plumbing service, reach out to the experts at Trust Rooter. We are a professional plumbing company offering a comprehensive range of plumbing services, including well pressure switch repair, drain services, lift station maintenance, backflow preventer repair, and many more.
Before you do anything, turn off the power to your well pump system at the circuit breaker or disconnect switch. This ensures you won't get electrocuted while working on the pressure switch. Your safety should always come first.
The next step is to open a faucet or valve downstream from the pressure tank to relieve pressure and drain water from the system. This step is crucial to preventing any unexpected bursts of water when you work on the switch.
Locate your pressure switch and remove any covers or enclosures that might be protecting the switch.
Inspect the switch for any signs of water leakage. If you find water around the switch, it could indicate a damaged diaphragm or seal that needs replacement.
Next, examine the electrical contacts and wiring connected to the pressure switch. Ensure that the connections are secure and that there are no visible signs of damage or corrosion.
Set your multimeter to measure continuity. Then, disconnect the wires from the pressure switch terminals. Touch one multimeter probe to each terminal. If you hear a continuous beep or see a reading of zero ohms, it indicates that the switch contacts are closed and the switch is functioning correctly in the "ON" state.
