Leak coming on 2 inch main gas line found with gas sniffer and soap test. It was in a bad spot so we had to shut the gas down bleed the gas out so no sparks and cut out bad 2 inch BLk tee. After getting it all put back together we turned the gas on half way and tested for leaks. We then put it full and tested again. No leaks at the moment. Brad hit a conduit line behind the gas line that controls the heater. I believe they are calling an electrician. We came this morning to fix the leaks but as we were setting up the guys came up to us and said they smell gas again even when the gas meter was turned off. We diagnosed multiple things and narrowed it down to one of there machines causing the bad smell. It wasn’t a gas. Nicor came back out and tested things and found that there was a bad regulator out side. We pressure tested the system up to 10 psi and it dropped slowly so the leaks are still prevalent. We talked with there managers and they still want to continue on fixing the leaks asa
