A well pressure switch is an essential component of a well water system. It’s responsible for monitoring the pressure within the water tank and controlling the operation of the well pump. In other words, a well pressure switch maintains the desired water pressure in your home’s plumbing system by controlling when the pump turns on and off.
Just like the other parts of your well water system, the well pressure switch can malfunction for a number of reasons, including normal wear and tear, electrical problems, and more. A failing well pressure switch can lead to various issues, such as inconsistent water pressure, no water supply, energy inefficiency, frequent pump cycling, and many more. If you have a well water system in your home, it’s important to know how to test the well pressure switch and perform simple troubleshooting steps to ensure the switch continues to operate smoothly. In this guide, Mr. Rooter Plumbing outlines the basic steps to help you test and troubleshoot your well pressure switch.
For safety, the first step is to ensure the power supply to the well pump is turned off. You can do this by either switching off the circuit breaker or disconnecting the pump from its power source.
Inspect the pressure switch for any pressure adjustment settings. If present, make sure they are correctly set according to your system's requirements.
Attach a pressure gauge to a faucet or hose bib to measure the current water pressure in the tank. Compare this reading to your system's cut-in and cut-out pressure settings.
If you suspect an issue with the switch, you can manually test it. Gently turn the adjustment nut on the pressure switch counterclockwise. The pressure should drop below the cut-in setting, causing the pump to start. Then, turn the nut clockwise to raise the pressure above the cut-out setting, which should stop the pump.
While manually testing, pay close attention to how the pressure switch responds. If it fails to start or stop the pump at the correct pressure, it might be malfunctioning.
If you're not comfortable with this process or if the switch isn't behaving as expected, it's time to call in a nearby plumber. They'll ensure your well pressure switch is working correctly, which is essential for a reliable water supply.
To prevent pressure switch malfunctions, it's important to conduct regular maintenance, keep the switch and its housing dry, and address any issues promptly. Regular inspections and professional servicing can help identify and resolve problems before they lead to a complete malfunction.
