Step 1 · Preparation and Safety

Locate the circuit breaker that controls the well pump and switch it to the 'OFF' position. To be certain, go to the pressure switch near the tank and use a non-contact voltage tester to confirm there is no power. Close the main water shut-off valve, which is typically located after the pressure tank, to isolate the house plumbing. Open a nearby faucet (like a laundry sink) to relieve the pressure in the pipes and help drain the system.
