    Well, I think that's the first time I've ever seen ASVs installed (presumably) at least 6" above anything downstream...

    I've had a few AVB installs that were taller than that, but well hidden by mature plantings. Strictly a money choice I gave a customer. Beauty would require a RPZ, for which I'd want enough money to raise the install price by at least ten percent.

    One problem with a tall AVB install is that the vertical pipe is a bit wobbly. Even sch 80 pipe wouldn't make much of an improvement.

    If it was done right..in brass nipple stock...the cost of a RP would almost be
    a wash, no?...most certain would look better!!!!

    Brass? Oh, ha-ha. Show me a brass antisiphon valve. (not counting Champion or Lawnlife) If you can't see it, it only need endure the weather and the passage of time. The biggest problem for tall BP installs in our climate, is that the pipes are entering the soil where the foundation trench was backfilled, and not compacted. Much settling can occur.

    You missed my drift...brass for the uprights..no need for brass valves..
    brass comes up from 10" sleeved v.b.s w/conc. poured around the sleeves &
    pea gravel to stabilize the brass risers. Jeez, I bet that's class in the last pic?
    ROTAR?

    Brass anything is a needless extravagance, if a reliable PVC alternative exists. I have the germ of an idea I'll have to check with suppliers. One counter guy was trying to tell me that the days of the plastic antisiphon valve were coming to a close. Nothing I could confirm online.
