Control valve run's great when off, trickles when on.
I am having issues with 1 of 10 control valves. I have one valve that puts out just a little water when on, but runs great when off. I have done everything I can think of. I picked cleaned the valve, replaced the solenoid, rewired to another location on the controller, replaced the valve twice (once with the original Orbit, then with a Hunter PGV.) After all this, the symptoms are the same. Even with the controller unplugged or the valve disconnected, this is still the case. These valves both had manual operation by backing out the solenoids. In both cases, manually turning to the off position makes the water come out faster. Also, I did check to make sure the flow was the correct direction. Please help me find my sanity. I've done all I can think of. Thanks
