## Abstract

A system for collecting soapy water in a shower, or from other sources for flushing a toilet. The system comprises an auxiliary tank for receiving the collected soapy water and for supplying the water to the primary tank associated with the toilet. The system further comprises, according to a first embodiment, a frame assembly interposed between the upper end of the primary tank and the cover of the tank to provide the necessary operative interconnection between the primary tank and the auxiliary tank. In another embodiment, the frame assembly is integrated into the cover.

## Claims

### Claim 1

In a system for saving water by recycling soapy water collected at an accumulation site for flushing a toilet, said system comprising a primary tank coupled to a toilet bowl and an auxiliary tank disposed above the primary tank and communicating with the latter to supply the primary tank with soapy water, a first pipe to convey the soapy water from the accumulation site to the auxiliary tank and a second pipe to supply the soapy water from said auxiliary tank to the primary tank, a pumping element disposed in the first pipe to pump the soapy water to the auxiliary tank, the improvement comprising:
a) a frame capable of being placed between an upper end of the primary tank and a cover thereof, said frame having a first opening arranged to receive one end of said second pipe from the auxiliary tank to supply the primary tank with soapy water from the auxiliary tank and a second opening arranged to receive one end of a relief pipe by which water exceeding a predetermined level in the auxiliary tank passes to said primary tank, said frame including an outwardly and downwardly extending flange which provides a seat surface to freely and removably rest on the upper end of the primary tank; an upper end of said flange acting as a support on which the tank cover can freely and removably rest; and
b) a float assembly fastened to said frame and comprising a pair of arms extending parallel to each other and at least one float element attached to said arms.

### Claim 2 (depends on 1)

The water saving system of claim 1, wherein the float element comprises a hollow member secured to an extremity of each arm.

### Claim 3 (depends on 1)

The water saving system of claim 1, wherein the float element comprises a body secured by and between the extremities of said arms.

### Claim 4 (depends on 3)

The water saving system of claim 3, wherein said float element is cylindrical.

### Claim 5 (depends on 3)

The water saving system of claim 3, wherein said float element is spherical.

### Claim 6 (depends on 1)

The water saving system of claim 1, wherein the arms extend straight from one wall of the primary tank towards an opposite wall thereof.

### Claim 7 (depends on 1)

The water saving system of claim 1, wherein the arms include a bend thereon so that the float assembly occupies a limited area of the primary tank.

### Claim 8 (depends on 1)

The water saving system of claim 1, further including an inlet means to be located at the accumulation site and which has an inlet body with a plurality of depending legs.

### Claim 9 (depends on 1)

The water saving system of claim 1, comprising a flushing lever connected to said primary tank and valve means supported by said frame and connected to said second pipe and to said float assembly.
