Customer has water staining outside of front door on concrete. Performed several test to try and determine if customer has a active leak. After performing test it seems customer has a leak in her main feed for irrigation. Once I shut valve off for irrigation the meter would stop turning. When I would have the valve on the meter would slowly start to move. Due to the line being pvc was not able to to determine where the line ran or where the leak is. I believe the pvc line runs from the valve under customers front porch and over to ball valve on front left side of the house where the irrigation valves are located for sprinklers. Recommended possible having another company out to try and see if they can locate where leak is. Or having to re-route the line out under from front patio in the planter bed over to the side of the house.
