Irrigation/Rainbird Drip Irrigation - Won't turn off


I have a 4 year old home with a Rainbird drip irrigation system with one zone.  The drip runs constantly, even when I turn the system off at the controller box, the drip still runs.  I replaced the solenoid, no change.  Thoughts?

Hey Don, if you already replaced the solenoid, and that did not help, then you need to install a new diaphragm in the valve. Go to, and this website will show you how to replace the diaphragm. Good luck and have a great day.

I have been installing and repairing sprinkling systems since I was 15 years old. Have owned my own sprinkler system contracting business for over 26 years. It is basically the only job I've ever done, except for being a paper boy when I was young.
