    Here's a cute little piece of work. There is someone out there who likes to build above-ground manifolds with standard zone valves, with poly pipe leading from valve outlet to under the ground. And of course, no backflow (maybe a swing check in the basement plumbing)

    The addition of AVBs is my own, since I was tired of looking at them, and have little other use for them. It brought the system into genuine toxic-rated code compliance, for not too much money.

    Not only not too much money, but zero sense of aesthetics! :hammerhead:

    I wish they still sold those AVBs, now that we have entered the age of backflow theft.

    compliance over here is there must be a device that can be tested

    AVBs are approved for use on mortuary tables.

    It's only called a "device" if it cannot be tested, otherwise, it's an "assembly".

    a dual check is different from a double check ( mainly one can be tested and the other cant)

    I would like to see the documentation on dual check failures, being that they are not testable :confused:

    Dual/single checks, "flappers" are born to failure, which is why only idiots install them. :hammerhead:
