One of my zones has started to run with all of the other zones. I just changed out my valve due to this and the zone still continues to run with the others. Any ideas? Can’t figure out the issue. I have a 2nd generation Rachio.
Are you saying that you can turn on any zone and this one other zone turns on as well?
Yes
Interesting, hard to imagine. Maybe wire touching, but it would not be touching all. I wonder if the valve has some issue and another zone on causes the valve somehow to leak? Could that valve be connected where a master valve or pump would be?
