How to troubleshoot and solve the fault of the pump pressure switch

If you suspect a pump is not pumping water properly, the first step you should take is to check the Pump Pressure Switch. Ensure that the switch is not corroded by dirt or water by inspecting the electrical contacts inside. If the contacts are dirty or corroded, clean them with fine-grit sandpaper or an emery board. If the switch still doesn't work, there could be a leak in the plumbing connection. Tightening the connection to the pump may fix the issue.

General wear and tear is another potential cause for a pump Pressure Switch failure. The components may corrode and rust, preventing the switch from functioning properly. This also affects chemical compatibility, so it's important to match the pressure switch to the motor and pump. In general, the pressure switch should be in the center of its operating pressure range.

Once you have located the pressure switch, you can begin to troubleshoot the problem. Wiring a well pump Pressure Switch can be confusing, so it's important to label it and document it with a masking tape before replacing it. This way, you can avoid confusing your power supply with the pump motor wires and vice versa.

A Pump Pressure Switch must always be serviced by qualified electrical maintenance personnel. It must also meet the manufacturer's maximum pressure requirements and not exceed the manufacturer's recommended operating temperature.
