finally fixed it

it seems it was more than one thing. replacing diaphragms fixed one zone. it seems the other zone was either not having the manual valve all the way shut because tree roots were in the way or the roots were applying enough pressure to allow the water past the o ring. after taking apart all 3 valves that were in this box, i have a leak free box again, no tree roots and zones that stay closed. solenoids were replaced, but i had this issue with the control box totally disconnected ,as soon as i tur...

changed diaphragms still stuck open

replaced solenoids, still have open valve

i replaced the solenoids on 3 valves which were the closest to the house and all in the same underground box. i still have one circuit that runs when the controller is turned off and the water is on. it makes no difference if i open and close the manual valve on that circuit. i am guessing that i need a whole new valve unit? what makes the valve units go out in the first place? could it be from a power surge? this system was hardwired, but i am thinking to put it to a plug going through a surge ...

toro greenkeeper 212 no power to valves

or would i just be better off replacing the controller? I have 10 zones. at least 4 are open when i turn the water on now.when you said to maybe replace the module, is this the unit inside the controller or isthe module attached to the valve? i am trying to figure out if i have to replace valve parts or controller parts. thanks

toro greenkeeper 212 no power to valves

i threw the breaker to the unit because it was hard wired, and disconnected the battery. when i turn on the water, all the zones near the house are running. 1 more piece of information has come up. my neighbor has the exact same problem. i am not sure of his brand controller. so next question, is it toast or can i replace a part? thanks for the help
