A toilet flush water supply control unit (10) which enables hot water to be immediately available at a hot water faucet (56), is described. The control unit (10) is formed from a first fluid conduit (12) and a second fluid conduit (20). The first fluid conduit provides a passage (12C) between the cold water supply (52) and the toilet flush tank (40). An intermediate opening (12D) in the first fluid conduit is opened and closed by a thermostatic device (21) mounted in the second fluid conduit. The thermostatic device allows cool water in the hot water system to flow into the first fluid conduit and thus into the toilet flush tank. Once hot water reaches the thermostatic device, the device closes. A valve (28) which is manually controlled by a handle (29) attached to the toilet flush tank, allows the user to turn the control unit on and off. The unit saves water and at the same time provides convenience of use.

A toilet flush water supply control unit which comprises: (a) a first fluid conduit having a passage with an inlet and outlet for directing cold flush water into a toilet and with an intermediate opening in the conduit into the passage; (b) a first check valve means mounted adjacent to the inlet of the first fluid conduit to the passage for controlling the flow of the cold flush water into the passage; (c) a second fluid conduit mounted on and closing the intermediate opening in the first fluid conduit; (d) a thermostat means mounted in the second fluid conduit for controlling the flow of water from a hot water supply into the passage which is controlled by the temperature of the water from the hot water supply to the thermostat means such that the thermostat means is open when the water from the hot water supply is cool and closed when the water is hot; and (e) a second check valve means mounted in the second fluid conduit preventing the flow of the cold flush water through the intermediate opening and out of the second fluid conduit and allowing flow of the water from the hot water supply into the second fluid conduit wherein the control unit allows cool water from the hot water supply to flow through the second fluid conduit until the water becomes heated and then the thermostat means closes the second fluid conduit when hot water moves through the second fluid conduit to the first fluid conduit and thereafter only cold flush water is supplied to the toilet through the passage between the inlet and outlet of the first fluid conduit and wherein the first check valve means is closed when the thermostat means is open and water from the hot water supply is flowing through the second check valve means and past the thermostat means.
