Answer: 
The purpose of an anti-siphon valve is to dump residual line water and prevent it from entering your water supply. Anti-siphon valves should be installed above the highest point in the system. Installing the valve below supply lines and spray heads will cause residual water to flow back to the valve and released through the cap. The amount of backflow is not caused by the valve.
