For this job I work on the gas system. Customer had a leaking gas line going to the water heater. Due to the line being old 3/8 copper. The line needed to be replaced. With customer approval I ran about 45ft of 1/2 TracPipe from the main line to the location of the water heater. Once installed I did a pressure test. Once passed I turn the gas on and recite water heater. Everything is back running probably. No other issues was found thanks for choosing TE Certified.
