The instructions that came with my ASV valves say not to have a valve down stream of the ASV valve or damage may result. It appears to work for you. I wonder what they are worried about.

My current system uses a Rainbird asv valve as my main valve. If it works in my situation it should be fine for you.

Yes, ASV anti-siphon valves are made by Hunter and Rainbird. I am installing a sprinkler system in established flower beds and don't want to dig things up. I figured that using the anti-siphon valves with poly tubing covered by the mulch was the least disruptive way to go. The valves are clustered in a central spot with the poly tubing going out to the sprinkler heads.

I believe ASV valves are anti-siphon made by Rainbird, correct? If you have anti-siphon valves, such as the ASV, you do NOT need a backflow device.

ASV Valves

If I use all ASV valves is there a need to install a main line backflow device?
