ABSTRACT:
A wall mountable vacuum breaker is disclosed. In one embodiment, there is an escutcheon mountable against the wall over a wall opening, the escutcheon having openings alignable with fluid supply and outlet pipes which terminate near the opening. There are also a pair of couplings connectable to the respective pipes through the escutcheon, with at least one of the couplings being shaped so as to bear against an outwardly facing surface of the escutcheon when the coupling is connected to the pipe. This holds the escutcheon against the wall. A fastener is provided to connect the main valve body to the respective couplings. In an especially preferred embodiment, there is provided a decorative shroud that is removably mounted to the valve body so as to enclose the valve body and the fastener.
