If you have a water heater that uses a gas line, you may need to purge the air from the line periodically. This is typically done when the line is first installed, but it may also need to be done if the line has been disconnected for any reason. Purging the air from the gas line will ensure that your water heater is able to function properly.
- Turn off the main gas valve to the house
- Find the gas valve on the water heater and turn it to the “off” position
- Open the water heater’s drain valve and release all the water from the tank
- Close the drain valve and open the cold water inlet valve
- This will allow fresh water to enter the tank and displace the air
- Close the cold water inlet valve when water starts coming out of the drain valve
- Turn the gas valve to the “on” position and relight the pilot light
