For this job, I came out for a gas leak. I could pin point where the gas leak is coming from. I checked and tested every exposed fitting and no leaks were visible or detected by gas detection device. The only fittings left to check for leaks are behind the fire place and will need fire place company to come out and take out the fire place walls in order to test remaining fittings that are not currently exposed. Customer is aware and will have fire place company out.
