I just put in new manifold with rain bird control valves. Ran a manual test and one station will not turn off. So I turned off my control box. Still on.Disconnected all wires.Still on. The only way I can turn off system is to turn off the water coming in.
Make sure the diaphragm is ok. Someimes the seat washer is messed up on a new valve.
Take the solenoid off and see if the plastic white retainer is keeping the valve from closing.
Not sure which valves or solenoids you have.
Is there a lever under the solenoid? Make sure that's not flipped on.
