For this job, I rendered lead detection for original technician Tony. I immediately isolated the Watermain service between the meter and the shut off in the basement however, once I listened, I could hear turbulence all throughout the line, so I decided to try and put compressed air on the line by shutting the meter off and air up the hose bib in the front of the home to push air back towards the meter I was not able to turn the meter off Even with the curb stop in the off position. The meter still continue to turn also noticed that the meter box was full of water and is leaking on the dual check valve inside the meter box.
