Abstract
A selectable toilet-water-level flushing system (10) that allows a toilet user to selectively control the quantity of water that is used for a toilet flush. The quantity of water used depends on whether liquid or solid waste is to be flushed. For liquid waste, only a partial flush is necessary; for solid waste, a full-flush is used. The system (10) functions by performing a simple modification to the toilet flush valve (12). The modification consists of inserting into the valve opening a weight (16) that causes the normally buoyant valve to become non-buoyant. Since the valve is non-buoyant, the lifting of the valve from the valve seat (36) is totally controlled by the toilet flush handle (38) which, in turn, is controlled by the user. Typically, for a partial flush the handle (38) is temporarily held in its depressed position for two seconds while for a full flush, it is held for four seconds. Over a period of time, by using partial flushes a large savings of fresh water can be realized.
