Completion of the install of new back flow device and water meter. New meter is 7 inches longer than the previous one, this made it so the fill arm hits up against the metal edge of the doors opening. I fabricated a 3 layer protective sleeve out of pvc pipes and rubberized pvc fernco and hose clamps. City turn the water back on and we tested for leaks. They’re was a drip out of the compression nut on the first ball-valve, i removed the handle and tightened it up and the drip stopped. Recommendation get power to the box so a heat source can keep the valves, meter and backflow device from freezing.
