Ok to use Anti-siphon valves with Backflow prev?

Just curious cause I have both. Just want to know if this will cause too much friction loss for the sprinklers (rated at 30 psi -15 ft)? Any help appreciated. Thanks

I dont think it would cause too much of a friction loss. I typically install a seperate backflow device with inline valves.
