Have a timer with 5 zones active. One of the zones would not stop this morning. Tried to stop sprinklers manually by turning off the timer, but water would not shut off. Had to turn off water to irrigation system to stop the sprinkler. Is this most likely a problem with the anti-siphon valve getting stuck open? Or a problem with the timer? Sorry for the lack of details. Thanks much for your help.

I'm thinking it's the anti-siphon valve. Came home and unplugged timer - turned on water and the sprinklers came on again. The solenoid looks a bit corroded and probably has dirt or something inside. Will replace and see what happens.

The valve operates by that solenoid opening a bypass orifice, which causes the main valve to spring open. If you get a grain of sand in the solenoid-orifice seat, the valve will not turn off.

Solution, unscrew the solenoid, clean it out.

Unfortunately, removing/cleaning the solenoid didn't do it. A replacement solenoid at HD was almost as much as a new valve, so I replaced the valve - and I'm back in business. Thanks much for the input. -dog
