Step 1 · Preparation and Safety Precautions

Begin by ensuring the work area is safe. Go to your home's main electrical panel and turn off the circuit breaker that supplies power to the electric water heater. For added safety, use a voltage tester at the heater's electrical connection to confirm the power is off. Next, locate the cold water inlet valve for the water heater and turn it clockwise to shut off the water supply. Finally, place a bucket and some old towels on the floor beneath the expansion tank to catch any water that will inevitably spill during the process.
