My driveway slopes at about 16% for 75 feet. Near the base of it, but still on an uphill run, I have a seepage of about 5 to 8 GPM. I have isolated it to a pressure line of 50 to 80 PSI that exits a pressure tank and feeds the house and yard - it is 1.25" PVC
The roadway is asphalted with a deep base of gravel, so the true source of the leak is quite problematic to discover. I have used a stethoscope in the area of the seep, but results are confusing; cannot zone in on a noisy area. The pipe may be 18 to 25" deep.
Also in this trench, unfortunately, is 2" electric, 2" pumped effluent [far below the pressure line], telephone and another 1.5" water line from another source.
Any tricks to pinpoint this leak? I can turn up pressure to 100 psi and then.... tin can with ear on it like some motel room voyeur? Stethoscope with a rod attachment into drilled holes? [had one cannot locate it]
Tear it all up with the backhoe and block access for a few days and probably hit the electric first?
