ABSTRACT:
A toilet (10) and toilet system suitable for a boat, recreational vehicle, bus or the like is operated via a microprocessor controller to effect a convenient and efficient operation. The toilet includes a base assembly (30) having an electrically-operated flush valve that opens and closes a passage to a waste receiving area. A flush lever assembly (15) has flush lever displaceable from a neutral position toward one of a “flush” position and an “add water” position. In this context, the flush lever initiates a flush cycle in the “flush” position and initiates an add water cycle in the “add water” position. The controller communicates with a water inlet valve, the flush valve and the flush lever assembly. In operation, the controller opens and closes the water inlet valve and controls a position of the flush valve in accordance with a position of the flush lever.
