Step 1 · Turn Off Power and Water Supply

For an electric water heater, locate the corresponding double-pole circuit breaker in your home's main electrical panel and switch it to the 'OFF' position. For a gas heater, find the gas shutoff valve on the supply line leading to the heater's gas control valve and turn it to the 'OFF' position (the handle should be perpendicular to the pipe). Next, locate the cold water inlet pipe at the top of the water heater and turn its shutoff valve clockwise until it stops. This isolates the heater from power and water, ensuring a safe working environment.
