## Abstract

A water discharge dechlorinator unit includes a body having a first end adapted to be removably coupled to a water hydrant, such as a fire hydrant. The body defines a water passageway between an inlet and an outlet thereof. A chamber is in fluid communication with the water passageway and configured for reception of dechlorinating material therein, such as chlorine neutralizing tablets, whereby water from the fire hydrant passes from the water passageway and over the dechlorinating material in the chamber so as to neutralize chlorine in the water before it is discharged from the unit.

## Claims

### Claim 1

A fire hydrant water discharge dechlorinator unit, comprising:
a body having a first end adapted to be removably coupled to a fire hydrant, the body defining a water passageway between an inlet and an outlet thereof; and
a chamber fixedly attached to and fixedly extending through a side wall of the body and having a bottom surface fixedly suspended in the water passageway, the chamber defining an inner cavity configured for reception of dechlorinating material therein, the inner cavity being in fluid communication with the water passageway through only a single aperture in the bottom surface of the chamber, whereby water from the water passageway is drawn into the inner cavity, circulated over the dechlorinating material to create a homogeneous mixture of dechlorinating material and water, and returned to the water passageway through the single aperture in the bottom surface of the chamber with solute from the dechlorinating material so as to neutralize chlorine in the water before it is discharged from the body.

### Claim 2 (depends on 1)

The dechlorinator unit of claim 1, wherein the chamber extends from the side wall of the body in a direction generally non-parallel to the water passageway.

### Claim 3 (depends on 2)

The dechlorinator unit of claim 2, wherein the single aperture in the bottom surface of the chamber consists of a multi-diameter aperture defining a water inlet and outlet of the chamber.

### Claim 4 (depends on 3)

The dechlorinator unit of claim 3, wherein a first portion of the multi-diameter aperture adjacent the water passageway of the body is of a smaller diameter than a second portion of the multi-diameter aperture adjacent to the inner cavity.

### Claim 5 (depends on 1)

The dechlorinator unit of claim 1, wherein the body includes an internally threaded swivel attachable to the fire hydrant outlet.

### Claim 6 (depends on 5)

The dechlorinator unit of claim 5, including a coupling attached to the swivel at one end thereof and to a barrel of the body at a generally opposite end thereof.

### Claim 7 (depends on 5)

The dechlorinator unit of claim 5, including a diffuser plate associated with the swivel.

### Claim 8 (depends on 1)

The dechlorinator unit of claim 1, including a first diffuser in the water passageway before the chamber and a second diffuser in the water passageway after the chamber.

### Claim 9 (depends on 1)

The dechlorinator unit of claim 1, including a cap removably attached to the chamber for manually inserting and removing dechlorinating material within the inner cavity.

### Claim 10 (depends on 9)

The dechlorinator unit of claim 9, wherein the dechlorinator material comprises at least one tablet comprised of chlorine neutralizing material.

### Claim 11 (depends on 1)

The dechlorinator unit of claim 1, including a water discharge directing nozzle rotatably attached to the body at the outlet thereof.

### Claim 12

A fire hydrant water discharge dechlorinator unit, comprising:
a swivel having a first end adapted to be removably coupled to a fire hydrant;
a coupling having a first end attached to a second end of the swivel;
a barrel attached to a second end of the coupling, the barrel defining a water passageway between an inlet and outlet thereof;
a chamber fixedly attached to and fixedly extending through a side wall of the barrel and partially extending into the barrel intermediate the inlet and outlet of the barrel in a direction generally non-parallel to the water passageway of the barrel, having a bottom surface fixedly suspended in the water passageway, the chamber defining an inner cavity configured for reception of dechlorinating material therein, the inner cavity being in fluid communication with the water passageway through a single water aperture in a bottom surface of the chamber, wherein the singe water aperture is multi-diameter, whereby water from the water passageway is drawn into the inner cavity, circulated over the dechlorinating material to create a homogeneous mixture of dechlorinating material and water, and returned to the water passageway of the barrel through the single water aperture so as to neutralize chlorine in the water before it is discharged from the dechlorinator unit; and
a diffuser disposed between a fire hydrant connection and a discharge outlet of the dechlorinator unit.

### Claim 13 (depends on 12)

The dechlorinator unit of claim 12, wherein a first portion of the single water aperture adjacent the water passageway of the barrel is of a smaller diameter than a second portion of the single water aperture adjacent to the inner cavity.

### Claim 14 (depends on 12)

The dechlorinator unit of claim 12, wherein the diffuser comprises a diffuser plate associated with the swivel.

### Claim 15 (depends on 12)

The dechlorinator unit of claim 12, wherein the diffuser comprises a first diffuser in the water passageway before the chamber and a second diffuser in the water passageway after the chamber.

### Claim 16 (depends on 12)

The dechlorinator unit of claim 12, including a cap removably attached to the chamber for manually inserting and removing dechlorinating material within the inner cavity.

### Claim 17 (depends on 16)

The dechlorinator unit of claim 16, wherein the dechlorinator material comprises at least one tablet comprised of chlorine neutralizing material.

### Claim 18 (depends on 12)

The dechlorinator unit of claim 12, including a water discharge directing nozzle rotatably attached to the barrel at the outlet thereof.
