For this job rendered leak detection services as a TGL for technician Corey Strickland. We isolated the Watermain service from the irrigation system and between the heater and the shut off in the basement we did detect what sounds like a leak about 3 feet off of the driveway in the middle of the yard Just south of the flower bed in the center of the yard we marked location with a flag due to the depth of the line however, if this is a spot repair, I recommend and exploratory dig before moving forward. Due to the depth of the line and how small the leak is, we did put compressed air on the line and we’re only able to detect any sound of a leak in the area located.
