To turn off your water heater, you'll need to take different steps depending on whether you have a gas or electric model. Here’s a breakdown:
Turning Off a Gas Water Heater
-
Turn Off the Gas Supply at the Unit: Locate the gas shut-off valve on the gas supply line leading directly to your water heater. Rotate the valve lever 90 degrees so it's perpendicular to the gas pipe. This closes the valve and stops the gas flow to the heater.
-
Consider Shutting Off the Main Gas Supply (Optional): For extra safety, you can turn off the main gas supply to your home. This is usually located near your gas meter. Turn the valve to the OFF position. Important: After turning off the main gas supply, a professional may be required to restart your gas appliances.
-
Turn Off the Water Supply: Find the cold water inlet pipe going into your water heater. There should be a shut-off valve on this pipe. Turn the valve clockwise until it stops. This will stop the water flowing into the tank.
Turning Off an Electric Water Heater
-
Turn Off the Power Switch on the Unit (If Applicable): Some electric water heaters have a power switch located directly on the unit. Turn this switch to the "OFF" position.
-
Turn Off the Circuit Breaker: Locate the circuit breaker in your electrical panel that controls your water heater. Flip the breaker to the "OFF" position. Important: This is crucial for safety when working on or around an electric water heater.
-
Turn Off the Water Supply: Just like with gas heaters, find the cold water inlet pipe and turn the shut-off valve clockwise until it stops.

Important Considerations:
- Always exercise caution when working with gas and electricity. If you're uncomfortable with any of these steps, contact a qualified plumber or electrician.
- If you are turning off the water heater for an extended period, consider draining the tank to prevent sediment buildup and potential damage.
- After turning the water heater back on, follow the manufacturer's instructions for relighting the pilot light (for gas models) or allowing the tank to fill completely before turning the power back on (for electric models).
