A water recycling device, wherein gray water from a bathroom sink is reused to flush a toilet. The device includes a gray water reservoir, means for sensing the level of water in the toilet tank, a pump to transfer water from the gray water reservoir to the toilet tank, and a mechanical means to stop the normal potable water supply from filling the toilet water tank as long as sufficient water is being supplied from the gray water reservoir. The mechanical means physically holds the float valve of the fresh water line closed by holding the float in the up position, unless there is no flow of gray water into the toilet's tank, in which case the float is released, allowing the normal potable water supply to fill the tank.
