If you put in a brass backflow device you will never have to worry about
individual anti siphon valves again.
It will require a plumbing permit and an inspection to install it, but once
in the rest should be just regular valves.

What is good brand of anti siphon valves for sprinkler systems ( the thing
that has the solinoid on it, wires coming out of it, opens the valve to
let
water flow), I have had to replace these cheap black ones my gardener
installs several times.
thanks
