    Hello Alex

    Perhaps you can answer a question.
    In reference to this thread;

    Is it allowed to have a shutoff past an AVB?

    PVB (pressure vacuum breaker): 2 shut off.
    AVB (atmospheric vacuum breaker): just one shut off.
    Both looks kinda similar but is not.
    You're totally right, not allowed.
