Not really sure
I just bought a house that has a rain bird e12 system installed I tryed reprogramming the controller and I have went around and turned all the valves on manually and all my heads work. If I leave all the valves on all the stations come on at once and then I turn them off one one station will come on and won't move on to the next one. I know it prolly not the best explanation of what's going on but I am new at the whole in ground sprinkler thing if anyone has any advice what could be happening I would greatly appreciate. Thanks justin
