Irrigation system won't shut off

So I same home a few weeks ago after a huge storm during the day, to find that one of the zones in my irrigation system had been running all day. I didn't have time to diagnose it at that point so I just shut off the water at the valve to the system. I went to diagnose it today and found that the solenoid to that zone was pretty hot. So I replaced the solenoid with a new one, turned on the water and same thing, that one zone was stuck on. So I shut off the water and moved the solenoid to another zone and the fault traveled with it. I know the problem is electrical, but I can entirely disconnect that solenoid from the system and that zone will continue to run. I was thinking that maybe I had a power surge during the storm that could have fried the controller, but it's plugged into a surge protector. I'm kind of at a loss right now so any help would be appreciated.

Hi two6dk,

Sorry for the delay in answering your question!

Your guess is most likely correct ... the controller is "fried" or the wire for that zone is damaged.

What you describe sounds like the controller has that zone stuck in the "On" position.

Even though you have a surge protector on your power source, energy can connect to your system on the control wires in the ground.

What makes me believe this is the signal to open that zone is still being sent to that valve.

If the wire was damaged between the controller and the valve, the new valve you installed would not turn "On."

Try installing a replacement controller.

It this corrects the problem, reset and continue using your in-ground sprinkler.

If not, you may have to have a specialist install a new control wire.

Hope this helps.
