A toilet installation is disclosed which is especially suited for pleasure boats. A discharge tank is disposed under a toilet fixture and connected with it through an inlet orifice. A flexible obturating member comprising a flexible flap member and a downwardly opening cup-shaped float member is fixed at one side of the inlet orifice so that the flexible obturating member hangs in the discharge tank when the latter is not pressurized. Compressed air from an air compressor is carried through a conduit for pressurizing the discharge tank and expelling the effluent from the discharge tank through a drain orifice, the outlet end of the conduit is aimed at the underside of the float member so that compressed air issuing from the conduit thrusts the obturating member against the inlet orifice thereby sealing off the discharge tank from the tiolet fixture. A second tank for clean water is preferably provided having a distributor valve unit which selectively connects the hollow rim of the toilet fixture with the interior of the second tank for conveying flushing water thereto and brings the conduit into communication with compressed air from the air compressor. Liquid level detectors are provided in the discharge tank to detect the level of effluents. All nonreturn valves provided have similar open float members which are not in the effluent flow path.
A toilet installation comprising a toilet fixture, a discharge tank disposed beneath said toilet fixture and having a drain orifice and an inlet orifice in communication with said fixture, an obturating member adapted to sealingly mate with the edge defining said inlet orifice to seal it off and a source of compressed fluid connected to said discharge tank through conduit means for pressurizing said discharge tank and expelling effluent including waste matter through the drain orifice, wherein the improvement comprises said obturating member having a pliable edge portion serving as a hinge to connect said obturating member to one side of said inlet orifice, and to permit said obturating member to hang into said discharge tank in open nonsealed relationship to said inlet orifice when the latter is unpressurized, said conduit means having an outlet end proximate to and aimed at said obturating member whereby a blast of fluid issuing from said conduit means outlet end thrusts said obturating member back and urges it against the edge of said inlet orifice to sealingly close the latter.
