Water service line was leaking and water running out from under the front deck down the hill to the street. Located where service line came into the house and concluded it was in fact the water service leaking. Could hear a hiss from the inside wall of the garage where the shut off and PRV is located. Received approval to repair line. Dug up the line and found and old black poly line with a cracked fitting tying it in to and old pvc repair. Cut out the pvc section and Repiped the black poly back into the copper going through the concrete. Pressurized to ensure a leak free installation. Backfilled and sprayed off the porch and driveway. No further issue at this time.
