Toro Valve Gushes Water Out Top Vent?!?

    I tried testing my irrigation system for the 1st time this season, and the valve gushes water out the top vent and the sprinklers don't pop up.

    I thought it may have been a frozen popup, but the ones I looked at seemed to move freely when I pulled them up.

    Any help would be appreciated!

    Are you talking about a anti-siphon valve, or just a regular diaphram valve?

    Anti-siphon, i'm pretty sure. I'm not at home to check right now, but it has the round cap about the diameter of a soda can with a 1/2 " gap underneath where the water shoots out.

    I think the system he has was put in with every solinoid valve being a anti-siphon valve.

    I always replace those, and never try to fix them. But perhaps someone who's taken one apart can help him out.

    It sounds like the anti-syphon/reverse flow valve at the main supply. You can get a repair kit or just replace the whole thing. If its not properly drained over the winter it will pop (like a soda can in the freezer). That top part (where the water is shooting out of) might just screw right off.

    Simple fix, shouldn't run you more than $40 in parts assuming you didn't blow up any metal parts.

    Problem fixed. I just replaced the whole valve. At least it wasn't a field mouse plugging the pvc underneath my lawn or something!!!

    Thx for the pointers all.
