For this job, I did a leak troubleshoot for the homeowner. We isolated the main service between the meter and the shut off inside and there was no leak detected within opened up the main shut off and checked the meter again. I watched it for over 30 minutes the meter did not leak whatsoever. This is not a main service or supply leak. After we notated these two facts we went inside and tried to re-create the event, to no avail. I recommended the homeowner keep an eye on the situation and told her if anything arises to give me a call.
