Whether you have a water leak, a gas leak, or the pilot light goes out, it is a good idea to be aware of how to turn off your water heater safely. Turning off the water heater is crucial before beginning any type of maintenance. More often than not, the procedure for shutting it off are simple when there is easy access to the back settings and the supply piping.
1. First, you need to locate the water heater.
These are usually found in utility closets or the garage/attic.
2. If you have a gas water heater, the first step should be to find the temperature dial on the bottom area of the tank, usually in the front.
When you find it, turn the dial all the way to off. If you have an electric water heater, begin by locating the breaker box for your home. These are usually on the exterior wall of the house or in the garage. Pinpoint the breaker line that gives power to your heater and switch it to off.
3. Locate the plumbing line, usually near or at the top of the water heater.
Turn the valve off, and you will have successfully turned off the water supply.
4. If you need to drain the heater, now is the time.
Hook up a garden hose to the boiler drain and place the hose outside or in a bucket to drain the supply.
5. The next step will be to locate the gas supply line and its valve.
It is usually located right by the water heater. Turn the lever (perpendicular) or the knob (clockwise) to shut off the gas supply.
6. From there, you’re almost done.
Just locate the relief valve, usually near or at the top of the water heater. Turn the valve off and air will now be allowed to enter the tank.
That’s it! You’re ready to safely begin maintenance.
