    zone number 1 on my sprinkler system wont shut off. i removed the wiring from the controller, but when i apply water to the system, the zone stays on (some of the heads). I have irritrol 2400 valves, and when i manually turn the valve, all the heads in that zone turn on. When i turn it off, only some of the heads turn off. Any help is certainly appreciated!

    needa piece off advice!

    I'm not sprinkler expert, but guessing based on experiences with other stuff...

    The solenoid in your valve is probably stuck. Its probably out in the yard under a plastic cover plate. If you don't know which valve controls that zone, it might shut off if you tap it. Turn it off at the controller, turn the water on (so its running, but is turned off). Then use a screwdriver handle, or (GENTLY) a hammer handle. Tapping it to get it unstuck won't permanently fix the problem, but it will show which one needs replaced.

    Or just wait until someone who knows what they're talking about chimes in.

    Pull the bonnet, inspect the diaphragm for damage, clean the body of any debris.

    Well I was on the wrong valve. the reason I know this is via DIY troubleshooting tips.... tip number one turn sprinkler heads off so you can run other zones. Step 2, when done watering all zones, wait a few minutes for the top of the valve in question to shoot a two foot high fountain... At the base of the fountain you will find your valve!:weightlifter: Replace valve in question.

    Just glad valves are only 25 bucks!!!

    thanks for the responses.

    FYI, in case you don't know, the solenoids on many valves are replaceable. They only run $7 or $8 too! A LOT easier to replace than a complete valve too.
