Safety Precautions Before Starting

1. Turn the Electricity Off

For electric water heaters, turn off the electricity at the circuit breaker. When using gas water heaters, turn the thermostat to the “pilot” setting.

2. Shut off the Water Source

Turn off the cold water valve at the top of the heater to stop water from flowing while you work on it.

3. Let the Water Cool Down

Wait for the water inside the tank to cool down. It might take a few hours to do this.
