Customer called us out because he had a leak in a valve box and the handles to his back flow (DCA) were rusted and broke off. Customer decided to replace the DCA up to code which we also installed a PVC ball valve before the DCA. Also next to the new DCA we cut out and replaced 2 valves with rainbird 1in DVF valves. The leak was at the T going into one of the valves. After we finished the work we turned the water back on and the meter still moving at 0.34. We turned the ball valve off right before the DCA and the meter is still moving which is telling us there is still a leak on the domestic side of the water line or something in the house. We left the PVC ball off leading to the irrigation for now.
