A propane gas provider called ASAP Drain Guys & Plumbing because of a leak in their company parking lot.
The ASAP technician cut the concrete around the marked area, marked previously by Pulse Leak Detection. He then jackhammered the concrete and dug a trench approximately 2 feet deep. There is a 3/4″ copper line in the ground but the technician did not see a leak. The technician listened to the pipe and shot CO2 through the waterlines. He then cut the concrete approximately 3 more feet from the flagged location away from the building, dug another trench 2 feet deep but was again unable to find the leak.
The business manager asked that a new shut off valve be installed on the copper line in order to stop the leak. The ASAP technician installed a 3/4″ ball valve to the copper line. When the valve was turned off, the utility sink had no water but the leak was still occurring.
The ASAP technician advised that in order to repair the leak, he would need to continue chasing the copper line until the leak is found or find the tee fitting feeding the utility sink and cap off the line feeding the utility sink. ASAP backfilled the trench and provided the customer with an estimate to cap off the line to the utility sink.
