Replace fitting that is leaking on gas line Arrived to home for gas smell. Customer had someone here with a sniffer to find out where leak was coming from. Leak was coming from 90 fitting in crawl. Went in crawl to confirm with bubbles. 90 was leaking. No other fittings near by were though. Left options. MyGuy replace 90 that was leaking and turned gas back on. Tested for leaks using bubbles on part replaced and nearby fittings. No leaks at this time.
