## Abstract

A secondary toilet reservoir water shutoff system and method for use in the water tank of a toilet assembly. The secondary toilet reservoir water shutoff having a beneficial use with toilets to prevent the wasting of water in a failing system. The secondary toilet reservoir water shutoff being activated by a toilet flush handle causing rotation of a timing device thereby opening of a secondary valve for a period of time allowing for the passage of water, the time determined by the degree of rotation of the timing device.

## Claims

### Claim 1

A secondary toilet reservoir water shutoff comprising: a housing having an inlet and an outlet, said housing including a conduit configured to permit passage of water from said inlet through said outlet; a shutoff valve positioned between said inlet and said outlet; a timer coupled to said shutoff valve, operation of said timer opening said shutoff valve for a length of time ‘x’, said timer including a timing arm coupled to a handle flush arm; wherein the rotation of said handle flush arm rotates said timer counter-clockwise to open and to permit the flow of water through said conduit, and said timer mechanically rotates clockwise to return to a closed position over length of time ‘x’.

### Claim 2 (depends on 1)

The secondary toilet reservoir water shutoff of claim 1 wherein said conduit includes an outer wall and an inner wall, having a proximal end constructed for cooperatively engaging the inside wall of a toilet reservoir.

### Claim 3 (depends on 2)

The secondary toilet reservoir water shutoff of claim 2 wherein said proximal end includes threading about one of said outer wall and said inner wall.

### Claim 4 (depends on 1)

A secondary toilet reservoir water shutoff of claim 1 wherein said length of time ‘x’ is defined where ‘x’ equals the range between fifteen seconds and two minutes (15 sec<x<120 sec).

### Claim 5 (depends on 1)

A secondary toilet reservoir water shutoff of claim 1 wherein said timer cannot be bypassed.

### Claim 6 (depends on 1)

A secondary toilet reservoir water shutoff of claim 1 wherein varying the point of coupling along a length of said timing arm will influence said length of time ‘x’ for permitting the flow of water through said conduit.

### Claim 7 (depends on 1)

A secondary toilet reservoir water shutoff of claim 1 wherein varying the point of coupling along a length of said handle flush arm will influence said length of time ‘x’ for permitting the flow of water through said conduit.
