Abstract: A closed system water conservation apparatus for connection to a hot water supply and delivery system includes a first valve disposed along the hot water conduit upstream of the delivery opening for selectively directing water between a first path for receipt and distribution by the delivery opening and a second path for use by a toilet; a second valve disposed along the hot water conduit upstream of the toilet, the second valve being in fluid communication with the cold water source and the first valve for selectively directing water to the toilet from at least one of the second path and the cold water source, and a water transfer conduit extending in fluid communication between the first valve and the second valve along the second path for intermediate cold water flow therethrough between the first valve and the second valve.
