What happens if the sprinkler valve does not shut the water off?

This is usually caused by debris stuck in the valve which is causing the rubber diaphragm not to seat properly. Cleaning out the valve and inspecting the diaphragm usually fixes the problem.

But not always...

The reason your sprinkler valve may not turn the water off could either be Electric or Hydraulic. It is important to determine if the problem is an electrical issue or a hydraulic issue before you start repairing the system.

Turn the control timer to OFF. Did this turn the water off? If yes, this could be a programming issue and the control is simply not sending a signal to the valve to close.

If this does not work, unplug the controller timer. Did this turn the water off? If yes, the controller may have an electrical issue and will need to be replaced.

If this does not work, remove the top assembly of the valve and clean the rubber diaphragm and look for any debris that could be lodged in the valve chamber. Turn the zone on again and see if this fixed the problem.

Remove the solenoid and check for debris that could be stuck under the solenoid piston. Turn the zone back on and see if this fixed the problem.

As a last resort, purchase a replacement valve and replace the diaphragm, and complete top assembly with new parts.

The problem should be fixed.
