Connect the black or red wire from the electrical panel to the power terminal on the switch, securing it with the terminal screw. Inside the housing, a diaphragm reacts to the force of the water pushing against it; when you open a faucet, the pressure drops, and the switch closes its internal contacts, sending power to the pump motor to turn it on.
Avoiding Wiring Errors: Common Mistakes in Pressure Switch Installation
Another mistake is using undersized gauge wire for the run to the pump, which leads to voltage drop and overheated connections. Once tightened, restore power and test the system by slowly opening a faucet to ensure the pump activates smoothly without humming or tripping breakers.
Always double-check that the switch setting matches the pressure tank specifications and that the connections are torqued to the manufacturer’s recommendations to avoid arcing. When this switch malfunctions, it can cause the pump to run constantly, stop working entirely, or cycle on and off too frequently, which leads to premature failure.
