I am new to the field and have been given a wide wide range of advice from supervisors and co-workers. I have at one point been told that any kind of leak, no matter how small, is a problem, while at other times told not to worry unless it is a large leak. I usually check a cutomer's lines on each service call with my sniffer, then use soap bubbles on any suspected leaks. I would estimate I find at least one leak at 25% of the jobs (some seem pretty small but they do bubble). I also am told that the other techs are not finding leaks. They all have more experience than me. In some cases, decades more. This leads me to beleive I may be overdoing it.
So, what is the best way to handle natural gas leaks?
