For more than 34 years, we’ve heard plenty of great questions from our customers. One of the most common questions we encounter is “how do I turn off my water heater?” We completely understand why this would be a common question. With so much happening in our everyday routines, one of the last things that we think about is our water heaters, but when it starts acting up, we have questions.

If you ever notice that your water heater is overheating, making strange noises, or performing unusually, it is critical that you do not allow the heater to continue running. The longer a water heater is running with one of these symptoms, the more severe the problem can become. This could leave you with leakage, flooding, or worse. Even if someone is coming out to work on the water heater, it is still better if you turn off the heater before they arrive.

Whether your home has a gas or electric water heater, follow these steps when you need to shut it off.

Shutting Down the Water Heater

 1. Turn off the gas or electricity:

  • Gas: Turn the dial atop the thermostat from the ON to OFF position
  • Electric: Flip the circuit breaker switch for the water to OFF

 2. Shut off the water supply:

  • Twist the handle atop the water valve clockwise, until it stops. Turn off the main water valve for the entire house ONLY IF the water DOES NOT stop

 3. Drain the water heater:

  • At the bottom of the tank, connect a hose to the drain valve. Place the other end of the hose in a lower spot where you are comfortable draining rusty, hot water

 4. Open the relief valve:

  • Flip the handle so it’s sticking straight out or up
