Sprinkler Station Won’t Shut Off – How to Turn Off Water Supply

One station runs continuously. Need to shut off water to sprinklers without affecting house.

Locate backflow preventer (usually after meter) – it has shutoff valves.
Close the irrigation isolation valve there.
Then replace the zone’s solenoid or clean/replace diaphragm. Valve removal not needed.
