Abstract:
An automatic flush water distribution system adapted to be connected to a selectively opened or closed source of pressurized water, said system including a water distribution pipe adapted to be connected to said source of pressurized water, said pipe having a plurality of water distribution ports formed therein and a vertical flush pipe having a first end connected to and in liquid communication with said water distribution pipe and a second lower open end;said vertical flush pipe including at least one valve seat and at least one buoyant float valve located in said flush pipe between said valve seat and the first end of the flush pipe, said float valve and said valve seat having mating surfaces wherein when pressurized water is applied to said water distribution pipe, the float valve is held closed by the pressurized water against the valve seat and when the source of pressurized water is closed, water pressure in the water distribution pipe is relieved and the float valve floats in the flush pipe opening the valve and allowing remaining water in the distribution pipe to be discharged through the second end of the flush pipe, thereby creating a partial vacuum in the water distribution pipe to draw atmospheric air through said ports to dislodge debris therein.
