For this job, I rendered leak detection services attempted to locate the leak in the yard even did an exploratory dig I did locate the pipe but did not locate the leak pipe is exactly 3 3/4 feet deep and 30 yards away from 285 which made sonar detection impossible. The service main is made of blue poly and has already had one repair previously two years ago. There is a courtesy gate valve just in front of the meter box. I would recommend full replacement and a new courtesy valve installed in front of the meter box.
