Today we showed up for a water heater diagnosis. Upon arrival of the gas water heater was not lit, be homeowner said he tried to relight the water heater and nothing was happening. When we arrived we opened up the gas flex line to make sure that the unit was getting gas. We hooked the gas line back up together, and re-lit the water heater. The water heater had no problems lighting up, but there is a small crack on the front casing of the gas control valve. It is nothing to be concerned about. I left a estimate inside the email for a new gas control valve if this were to go out again, then that would need to be replaced. Thank you for choosing comfort experts!
