Client has us out because him and his wife smell a gas leak somewhere on the property. We were out a few weeks ago and installed so,e gas piping and a shut off valve behind the stove that I bubble tested prior to leaving so we know the leak isn’t from there. With a gas sniffer I was able to locate the leak at a transitional fitting from the black iron service to the CSST piping ran for the stove down in the crawl space. Client does not want to contact the contractor who did the install and would rather get it repaired or replaced through us. I presented options and today we went with just a repair, work is complete and gas is back on with NO leaks.
