Upon arrival, the customer showed us an area that was constantly holding water in the front beds against the house. Ran station 1 in the front beds and found no leaks on the lateral lines or risers. Also confirmed that the valve for station 1 was not sticking or seeping. Shut off the DCA for the irrigation & observed that the meter was spinning at a steady pace, indicating a leak on the domestic line. Confirmed that no water was being used inside the house. Informed the customers that the leak was on the domestic line.
