How To Shut Off Your Water Heater
You’ve probably somewhere seen the sign, “In Case of Emergency, Break Glass”; well, in the case of a water heater emergency, you don’t need to break anything – you just need to shut off your water heater. And make sure you shut off the water heater before anything else gets broken or damaged.
What types of emergencies require using your water heater shut-off valve? If there’s puddling around the water heater or, in the case of a gas water heater, you smell gas or hear a hissing sound, you’ll need the shut-off valve
Turning off the water heater in an emergency is an important step to prevent further damage or hazards. You could give us a call here at Benjamin Franklin Plumbing to turn off the water heater for you, but any homeowner can do this. And you should do it, because shutting off the water as soon as possible in an emergency is essential in order to prevent a puddle of water around a leaky water heater.
You’ll also need to learn how to use your water heater shut-off valve in non-emergencies, such as when you are going to be away from the house on vacation or for any extended time. Using the shut-off valve on your water heater when it is not in use for extended periods, such as when you are away on vacation, is also a good way to prolong the useful life of the equipment.
There are different kinds of water heaters, either gas or electric, or tankless. Here’s a general guide to using your water heater shut-off valve in an emergency for:
- Traditional electric water heater tanks
