How does an anti siphon valve prevent backflow?
If you use anti-siphon valves for backflow prevention all of your zone valves MUST be anti-siphon valves. When you use other valves after the anti-siphon valve the valves trap the pressurized water in the pipe when they close, This pressure keeps the vent in the anti-siphon valve from opening.
