Responded to a gas leak call under the trailer in the same location as a previous service. Found leak at a coupling with non-standard CSST line and fittings. Applied pipe dope and tightened the coupling, which temporarily resolved the leak. Customer accepted estimate to replace entire line with gas-tight CSST due to reliability concerns with current non-standard fittings. Parts ordered for follow-up installation requiring approximately 2-3 hours of labor.
