I was on a vacation and when I got back my tree drips were on and have been for some time. I’m sure my water bill will reflect that. The shrubs weren’t soaked all the trees were so I’m assuming the solenoid is stuck and that’s why it stayed on. I cut the power of the Rancho and unplugged the transformer from it and still water was flowing. So I’m assuming the solenoid is bad. Somebody let me know if you can. Thanks ahead of time.
I would say … try to Replace the Solenoid to see if it continues flow of water when Rachio’s power is off !!Do updates us grrecc
Yes, 100% the solenoid of power is cut and a zone still runs.
OK, so I had shut the water off. Shut the power off to the controller. The water finally stopped coming out when I turned the water completely off going to the drip system. Then I held the solenoid to see if I could feel open up when I turn the power back on and turn the water on and it works perfect. But I don’t want to have that happen again, so I did replace that solenoid. Think of no other reason why it would do that. Thanks for the help.
The solenoid’s valve orifice can get stuck open with debris. Youll still feel it click but it just wont close
Most likely it is actually the diaphragm inside of the valve that either is damaged or has debris in it not allowing it to seat. If it was a solenoid issue, they usually fail closed or off.
It must be as it worked once then is running with it all turned off. Had to shut the water off again. Can I fix the valve? Never did one before.
Yes, you need to identify the make ane model of the valve, and buy a rebuild kit for it. Usually there are screw type tops, or “jar” type that have a big nut that unscrews. Open it up and inside there is usually a spring, rubber diaphragm assembly, and maybe another plastic piece or two depending on the model. That diapragm is what you want to replace. This is the cultprit in 95% of zones stuck open. Very rare to see a crack in the body of the valve, which would have similar symptoms.
I am having them both replaced with new everything, for peace of mind. Then I will know what brand they are and can move forward from there. Thank you.

If you haven’t pulled the trigger on that yet, post a picture of the valves and I’ll bet we can identify.
Sorry for the long silence. I had already pulled the trigger. I think they are hunters, but I have new ones and easier to get to. I will know better next time. Thanks for helping.

I personally like the Hunter PGV series of valves. Super easy to work on and parts are easy to come by at big box stores in a pinch.
