How Will I Know When My Water Pump Pressure Switch Is Faulty?, Shell Lake, Wisconsin

If you rely on a water well for your household drinking, bathing, and cooking, it’s important to be well-versed in its many parts. After all, if something goes wrong, the responsibility will fall on you to arrange for repairs—not a city or municipality. One of the most integral parts of a water well is the pump pressure switch, which features a spring that controls the pumping of water to your home. Use the following pump service guide to find out if yours is deteriorating, so you can get help before matters worsen.

A Step-by-Step Pump Service Guide to Finding Fault in Your Pressure Switch

1. Power Off & Locate the Switch

To ensure your safety, turn off the power being sent to your well pump system by removing the fuses or powering down the circuit breaker. Then, remove the cover over the pressure switch. You may need to use pliers to rotate the screw caps holding it in place. This mechanism is linked to the pipes inside your water well, and you may see several wires going in and out of the switch.

2. Check for Leaks

If this is the case, you can use the pliers to clamp onto the brass fixture and turn it clockwise in a full circle. This will tighten the switch and may stop the leak altogether. However, if it doesn’t, you’ll likely need a switch replacement.

3. Test the Pump

To see if your handiwork was successful, turn on a faucet so the pump has a chance to cycle. Be careful not to make contact with the switch while the power is on. If this mechanism doesn’t close when the water pressure drops, the spring inside of is broken or worn out, and the whole thing will have to be replaced. If you see sparks flying from the area, turn off power immediately and call a pump service professional.
