For this job, I did elite troubleshoot for homeowner isolated his main water service and discovered there was no leak on the main service and then opened the main shut off in the garage and observe the meter again. The meter was still spinning, so I immediately started the leak troubleshoot. The homeowner advised that he had a plumber come out earlier that plumber told him that he had a leak under the slab and gave him an estimate for a slab leak repair around $2800. After learning this, I started isolating valves inside of the home. Nothing stopped with the meter at that point I then checked the hose bibs on the exterior of the home and noticed the one on the front had a hose attached to it that was split and spewing water. I advised the homeowner it would be a good idea to winterize his hose bibs so we did, I then check the meter again and there was no water loss whatsoever. I recommend the homeowner buy a new hose before spring because the one he has a split.
