4th Maintenance Tip: Shutting Off Gas to Your Whole House
An adjustable wrench will work also, but the end of the gas meter wrench is slotted to fit perfectly over the shut off valve on your gas meter. To turn off the gas, simply engage the shut off valve with the wrench, and turn it Â¼ turn so that your wrench is now perpendicular or “cross ways” with the pipe.
Note that the lock out flange is aligned when the gas is OFF. These holes come together and allow the gas company to lock out the meter, as shown below:
