How to Shut Off the Water Heater in a Water Heater Emergency

Be Prepared for Almost Any Water Heater Emergency

Water Heater Emergency San Diego CAOne of the most frequent questions we receive from customers at Black Mountain Plumbing is “Exactly how do I shut off my water heater?” This is something EVERY SINGLE homeowner ought to know how to carry out in case of a water heater emergency.

If your hot water heater is overheating, making unusual noises or operating abnormally, it’s EXTEMELY IMPORTANT that you do not allow it to run; the longer your water heater carries on working, the more serious the problem could get and the more likely that you are going to have a leak, flooding or even worse. Even if you have called a water heater specialist to come look at the problem, it is still better if you can turn off the hot water heater before the specialist arrives to check your appliance.

Do-it-yourselfers who execute their own hot water heater maintenance will want to drain water from their hot water heater tank every 3 months to avoid sediment build-up and better operation and energy-efficiency. Before draining your water heater, you DEFINITELY need to turn it off to avoid the risk of scalding or electrocution.

If you have a electric water heater or a gas water heater, follow these instructions when there is any water heater emergency you must turn off your appliance.

Gas: Twist the dial on the top of the thermostat from the ON the OFF position.
Electric: Switch the circuit breaker for the water heater to the OFF position.

An outside driveway is optimal.
