Toilet for use in recreational vehicle and boats

Abstract

A toilet utilizes a pressurized fluid source providing a flush volume of less than 1 gallon. A removable discharge passageway is sealingly coupled at a first end to the toilet waste outlet and at a second end to a floor flange, and defines a trapway for providing a water seal therebetween. In one example, the water seal includes a water column, and the discharge passageway is configured to maintain at least about 80% of the water column therein when the toilet is pivoted about 10 degrees. In another example, an upleg extends vertically upward a distance sufficient to maintain a minimum water column within the upleg necessary to maintain the water seal between the bowl and the floor flange when the toilet is pivoted about 10 degrees. In another example, a support bracket maintains the second end of the discharge passageway generally fixed relative to the first end.
