AVBs, A/S valves, PVBs are all still allowed though. Go figure.
Yeah... no double checks for us. The only thing you can use a double check for is a fire sprinkler system. And no below grade installation of DCVAs or RPZs either. Everything must be above grade (mainly so that the tweakers can steal them and sell the brass for drug money)! Everything else has to be an RP device.... (or an ASV, AVB or PVB for small and residential jobs).
