An apparatus for utilizing gray water for flushing a toilet is provided including a holding tank with a top face, a bottom face, and a periphery formed therebetween thus defining an interior space. The holding tank has an inlet pipe connected to a source of gray water for receiving gray water therefrom. An outlet pipe is connected between the holding tank adjacent to the bottom face thereof and a toilet. A tee is situated on the outlet pipe between the holding tank and the toilet. The tee has an opening coupled to a water supply adapted to supply water of a first pressure. The tee further has a valve having a first orientation for allowing the flow of water only from the water supply to the toilet and a second orientation for allowing the flow of water only from the holding tank to the toilet. A pump is coupled to the outlet pipe between the holding tank and the compression tee. The pump is adapted to create a second pressure within the outlet pipe which is greater than the first pressure only during the presence of water within the holding tank.

1. Field of the Invention
The present invention relates to recycling methods and more particularly pertains to a new water recycling system for providing a back-up water source for a gray water supply which, in turn, is used to supply a toilet with water.
2. Description of the Prior Art
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
FIG. 1 is a schematic view of a new water recycling system according to the present invention.
FIG. 2 is a cross-sectional view of the tee of the present invention.
With reference now to the drawings, and in particular to FIGS. 1 through 2 thereof, a new water recycling system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, as designated as numeral 10, includes a holding tank 12 situated within a basement of a house with a top face, a bottom face, and a periphery formed therebetween thus defining an interior space. The holding tank has a vertical inlet pipe 14 connected to the top face thereof. Such inlet pipe is further connected to a sink 16, a washer 18, a shower 20, and a bath tub 22 of the house for receiving gray water therefrom.
For allowing the discharge of water when the holding tank is full, an overflow pipe 24 is connected to the holding tank adjacent the top face thereof and further connected to a sewer system. As an option, the overflow pipe may be fed to a garden or the like. In either embodiment, the overflow pipe ideally has a U-shaped portion to prevent the back flow of sewer gas.
