For this job, I did a leak troubleshoot for the homeowner. I discovered that when isolated between the home and the shut off in the basement, the meter did not spin and did not change numbers whatsoever. I observed this for over an hour with no change that I opened the shut off in the basement to Test to see if the meter was functioning properly so I opened the faucet check the meter. Everything worked fine. I isolated the sprinkler system/irrigation system/there was no change. There was no leak. The homeowner has had no change in their water bill.
