ABSTRACT:
A self-contained compact pedestal sized marine head comprised of a conventional marine or household size toilet bowl connected to a base which houses an electric motor drivingly connected to a self priming fluid pump. The pump has a single suction water inlet and a first and a second pump outlet. The first pump discharge outlet is fluidly connected via a first pump discharge conduit to the inside of the bowl to act as a rim feed. The second pump discharge outlet is fluidly connected via a second pump discharge conduit to a bowl discharge conduit which is sealingly connected to an opening in the lowermost portion of the bowl. A small nozzle is disposed coaxially within the pump discharge outlet conduit at the point where the end of said outlet conduit joins in fluid communication with the bowl discharge conduit. In this way, all water passing through said second pump discharge conduit upon flushing passes through said nozzle and becomes accelerated and turbulent, aiding the flow rate from the bowl and tending to break up solid matter therefrom. The combined flow from the second discharge conduit and from the bowl fixture then passes through an inverted U-shaped conduit having a one-way vent means for preventing reverse siphoning, and also having a unique unclogging feature. The electric motor may be driven by electricity from the generator or main batteries of the boat or from an independent supply.
