Embodiment Construction
[0063]The discussion of the present inventive concept can best be initiated with a reference to FIG. 1 which presents a basic illustration of a typical flush toilet commonly used in the United States. The reservoir 1 contains an available volume of water 2 for flushing. The water 2 is prevented from exiting the reservoir 1 by the flapper valve 4 which is firmly maintained in its seated position atop the drain orifice 5 by hydrostatic pressure. Upon a user's downward push of the flush handle 6, the lever arm 7 rotates upward, imparting a vertical pull on the chain 8. The chain 8, being connected to the flapper valve 4, consequently lifts the flapper valve 4, which, being pivotally attached to the overflow tube 9, “pops up” from its seated position. The flapper valve 4, being buoyant, becomes suspended by flotation on the surface of the water 3 while the weight of the water 2 provides a head of pressure to initiate the flow of water 2 through the drain orifice 5.
