This feature is exclusive to irrigation systems that incorporate normally open master valves where a leak is detected. Corrective action is needed to prevent water wastage or property damage from saturated soil from a continuous leak. If a leak persists beyond the Leak Detect delay period and then beyond the Extended Leak Delay period, the controller will immediately post an Extended Leak Alert and close a normally open master valve.

An example of how this works might be when a window washer connects into a quick coupler on the irrigation main to fill buckets of water in order to wash windows. Filling the buckets initially may cause a Leak Detect Alert. If the water is left on beyond the Extended Leak delay time period, the controller will take corrective action.  The Extended Leak alert allows normal irrigation to occur as scheduled. If the window washer corrects the condition by turning the water off, the controller will automatically clear the alert after the next irrigation cycle.
