Plumbing Fix #2: How to Turn Off a Water Heater

It’s important to know how to turn off your hot water heater in case it develops a leak, overheats, if you’re going out of town for an extended period of time, or to drain it.

There are two steps involved in turning off a water heater:

  • Turning Off Gas or Electricity to Water Heater: On gas hot water heaters, turn the gas supply knob on the water heater to the off position. For electric water heaters, flip the circuit breaker or remove the fuse that powers the water heater.
  • Turning Off Water to Water Heater: To turn off the water to a hot water heater, turn the shutoff valve on the cold water supply pipe going into the hot water heater clockwise.

    Dan,

    I’m 86 years old and unable to do most of the jobs at home anymore but I enjoy very much reading your emails. If they apply to our grown children and their families, I send the emails to them or discuss the projects with them. Thanks for the good that you do.

    Bob

    Hi Joe,
    That’s called water hammer, and it’s caused by the sudden change in pressure when you turn off the faucet. It can be prevented by installing a water hammer arrester or water expansion tank in the water line near your hot water heater. Watch our video on How to Prevent Water Hammer in Pipes to find out more.
