Step 1 · Turn Off Power to Well Pump

Locate the dedicated circuit breaker for your well pump in your home's main electrical panel. The breaker is typically labeled 'Well Pump', 'Pump', or something similar. Flip the breaker to the 'OFF' position. To be absolutely certain, test a faucet; if the power is off, the water will run until the pressure is gone and will not restart. For an added layer of safety, use a non-contact voltage tester on the wires at the pressure switch to confirm there is no live current.
