Abstract
A toilet system designed to use recycled 'gray water'. The toilet includes a toilet reservoir positioned above a toilet bowl with a first conduit connecting the reservoir with the bowl. A sinkable sphere, which acts as a discharge valve for the reservoir, seats on an inner surface of a cone-shaped, resilient valve seat positioned on top of the first conduit. A valve lifter is positioned below the sphere to selectively lift the sphere off the valve seat to open the reservoir valve and drain 'gray water' into the bowl. The toilet bowl also has a bowl valve for releasing 'black water' from the toilet bowl through a second conduit. Controls are provided to permit an operator to independently control both the 'gray water' coming into the toilet bowl and the 'black water' exiting the toilet bowl.
