Turning an irrigation controller to OFF should stop electrically commanded watering, but it cannot always close a valve that is mechanically stuck open. If water continues flowing, the valve itself deserves immediate attention.
Why a sprinkler valve can stay open
- Debris is trapped inside the valve
- The diaphragm is damaged or worn
- The solenoid or bleed screw is manually open
- An internal valve component is damaged
Controller problem or valve problem?
If the controller is off and the zone continues to run, a stuck-open valve is a common explanation. If the zone stops when the controller is turned off but starts unexpectedly later, programming or controller issues may be more likely.
Why this should be addressed quickly
A continuously running zone can waste substantial water, saturate landscaping, erode soil, and create drainage problems. If necessary, shutting off the irrigation water supply can stop the flow until the valve is repaired.
