What is a common sign of a stuck valve?

A common sign of a stuck valve is that the zone won't shut off. When a valve is stuck in the open position, it prevents the zone from stopping water flow, leading to continuous irrigation even when the system is turned off. This can result in overwatering of the area being serviced, and is often one of the most noticeable issues affecting an irrigation system.

While other issues may also indicate problems within the irrigation system, such as a zone not turning on, excessive water pooling, or inconsistent spray patterns, these symptoms stem from different underlying causes. A valve that won't shut off specifically highlights a failure in the valve mechanism, confirming that it's stuck. This unique scenario requires immediate attention to prevent water waste and potential landscape damage.
