The quickest diagnostic question is whether turning the controller to OFF stops the water.
If the water stops
Review controller programming, manual-run settings, and multiple start times.
If the water keeps running
A mechanically stuck valve, debris, diaphragm issue, or manually opened solenoid becomes more likely.
Protect the property
If water is causing flooding, shut off the irrigation supply if you can do so safely and arrange repair.
