Turn Off The Gas Supply To The Water Heater

How Do I Turn Off The Gas Supply To The Water Heater?

This question is one we are frequently asked by our customers.

It is a great question and one that every homeowner should be educated in, in case problems arise with their water heater. You might smell gas coming from your water heater,  it might not be performing as usual or the water heater may be leaking and it would be a good idea to know how to turn off the gas supply to the water heater. The gas can be turned off from the outside gas meter, which shuts off all gas to the house or at the water heater itself, which just turns off the gas supply to the water heater. Knowing how to shut off the gas from both places can really come in handy.

To turn off the gas supply to the water heater:

All appliances that require water or gas have a separate shut of valve usually within a few feet of the appliance. To find a water heaters’ gas shut off valve look for a single handle valve that would usually be located at the bottom of the unit about a foot or two out. The valve will look similar to the one in the image below.

Turn this valve in the clockwise position to turn the gas off. It should turn a quarter turn and valve is closed it will be perpendicular to the pipe it is connected to. If you can’t get the gas valve to turn, can’t find the gas valve, or if there are any other problems, there is a second option which is to turn the gas off to the whole house.

To shut off the gas supply to the house:

Finding the gas meter shut off valve is usually pretty simple, once you have located your gas meter. It is located right next to the gas meter that is found on the exterior of the house as shown below. The gas valve is on when it is parallel to the incoming gas line. When the valve is turned a quarter turn so that it is perpendicular, then the gas line is closed and the flow of gas is off. Typically, this valve can only be opened and closed with a wrench.
