I came outside to find a single zone, 10 of 12, running for no reason that I can figure out. I checked the Rachio app and it didn’t show anything running. I quick ran the zone, but it didn’t stop. I had to turn off the water at the backflow to shut it down.
The system has not run a full schedule for a while. I did a quick run of zone 11 this morning to ensure some potted plants I moved would get hit with overspray.
Is this a failed zone valve, something else? Rachio software error? Any ideas?
I am sure glad I was home as that water bill could have been much higher.
