Abstract
An omnidirectional backflow preventer and vacuum breaker for use with a plumbing fixture in which the discharge may be moved to a position within a body of water includes a body having an inlet and an outlet, a chamber connecting the inlet and outlet and an air vent opening into the chamber. There is a diaphragm positioned within the chamber which normally closes communication between the inlet and outlet. The diaphram prevents water seepage from the outlet from reaching the air vent and has an integral one-way check valve positioned at the inlet which permits air from the vent to pass to the inlet to remove a vacuum condition therein.
