Elevation on these things is critical.
Higher than all your spray heads?
I wonder if the zone runs uphill from the valve - wouldn't be the first time
replace the whole valve.
Take the valve out and flush the line for 5-10 minutes
Rain bird anti siphon leaks water after valve turned off
I'm at a loss. I have four anti siphon valves and three of the four work. The fourth I have replaced every part including replacing the entire valve unit. After turning off the valve water gushes out from the cap. It slows but continually leaks. When I take the cap off and siphon some water out, the water levels continues to rise. As stated I have replaced the diaphragm, the solenoid and the washer and cap. What else could it be? Thanks.
