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.
