Gas control valves are a vital component of water heater systems, as they regulate and control the flow of gas to the unit. Unfortunately, just like any other appliance, things can go wrong with your gas control valve, resulting in unpleasant odors within your home.

Leaking gaskets or joints are often caused by an incorrect installation, which allows gases to escape from the connection points and into your home.

Improperly installed burner parts can also cause a leaky seal around the gas control valve, allowing natural gas to enter your home without being properly regulated.

And lastly, incorrect regulator settings will cause too much pressure on the valve which can lead to leaks and odors.
