As water pressure drops below the preset cut-in point—often around 30 to 40 PSI—the diaphragm moves, allowing two internal contacts to connect. Adjusting the Pressure Settings Beyond basic operation, the diagram helps you understand how to adjust the differential pressure setting.
Well Pump Pressure Switch Relay Connection and Wiring Diagram
This allows you to determine if the issue lies within the switch itself, a broken contact, a loose wire, or a failing pump relay, saving time and money on unnecessary part replacements. By adhering to the visual instructions provided in the schematic, you protect your home’s plumbing infrastructure, maintain consistent water pressure, and extend the operational life of one of your home’s most critical mechanical systems.
The diagram will clearly mark the power terminals, typically labeled as L (load), 1 (line), 2 (line), and sometimes a ground symbol. Decoding the Internal Components Looking at a well pump pressure switch diagram , the first elements you identify are the electrical terminals and the internal pressure mechanism.
