Hi everyone, hoping for your thoughts/input. A friend has a sprinkler valve he replaced that won't hold back water on the last station when we turn on the water supply line to the irrigation system. I disassembled new valve for any debris (didn't work), ran through stations, solenoid functions and could hear it open/close but never holds back any water to that station. Replaced valve with 2nd new valve, ran through all the same tests and just never holds back the irrigation system flow through that last station when we turn on the supply line. Valves been replaced twice. Electrical has been checked. Baffled, any ideas? Thanks for any thoughts.
