Step 1 · Isolate the Water Heater
The first and most critical step is to make the work area safe. Go to your home's main electrical panel and locate the circuit breaker labeled for the 'Water Heater'. Flip this breaker to the 'OFF' position. If you have a gas water heater, turn the gas control dial on the unit to 'OFF' and close the manual gas shut-off valve on the supply pipe. Next, find the cold water pipe that enters the top of the water heater and turn the handle of the shut-off valve clockwise until it stops. This prevents new water from entering the tank while you work.
