Is the main irrigation water supply open?
Go to one of the irrigation valves and twist the solenoid 1/4 to 1/2 a turn counter-clockwise. If the valve opens and sprinklers turn on, your valve is working and you’ll need to check the controller and field wiring. If the valve did not turn on any of the sprinklers, the water to the valves is still off. Find the irrigation isolation valve and open it.
