Abstract

A molded waterway assembly for a centerset faucet including a hot water inlet tube, a cold water inlet tube, and a central body of a coupler overmolded within hot and cold water bodies of the coupler.

Claims

1. A waterway assembly for use with a centerset faucet, the faucet including a hot water valve, a cold water valve, and an outlet tube, the waterway assembly comprising a hot water inlet tube including opposing proximal and distal ends, a cold water inlet tube including opposing proximal and distal ends, and a coupler including a central body that defines a hot water intermediate channel, a cold water intermediate channel, and an outlet channel, the outlet channel, the hot water intermediate channel and the cold water intermediate channel formed integrally as a continuous unitary molded structure by the central body, the hot water intermediate channel configured to direct fluid from the hot water valve to the outlet channel, the cold water intermediate channel configured to direct fluid from the cold water valve to the outlet channel, and the outlet channel configured to direct fluid from the hot and cold water intermediate channels to the outlet tube, a hot water body overmolded onto the central body and the proximal end of the hot water inlet tube, the hot water body defining a hot water inlet channel configured to direct fluid from the hot water inlet tube to the hot water valve, and a cold water body overmolded onto the central body and the proximal end of the cold water inlet tube, the cold water body defining a cold water inlet channel configured to direct fluid from the cold water inlet tube to the cold water valve.

2. The waterway assembly of claim 1, wherein the hot water body extends at least partially over the central body to define a hot water valve interface for receiving and supporting the hot water valve and the cold water body extends at least partially over the central body to define a cold water valve interface for receiving and supporting the cold water valve.

3. The waterway assembly of claim 1, wherein the hot water body fills a first exterior opening in the central body and the cold water body fills a second exterior opening in the central body.

4. The waterway assembly of claim 1, wherein the hot water inlet tube and the cold water inlet tube are formed of a polymer.

5. The waterway assembly of claim 1, wherein the hot water inlet tube and the cold water inlet tube are formed of cross-linked polyethylene.

6. The waterway assembly of claim 1, wherein the coupler is formed of a polymer.

7. The waterway assembly of claim 1, wherein the coupler is formed of cross-linked polyethylene.

8. The waterway assembly of claim 6, wherein the outlet channel, the hot water intermediate channel and the cold water intermediate channel are integrally molded within the central body.

9. The waterway assembly of claim 1, wherein the hot water intermediate channel is L-shaped as including a hot water vertical portion and a hot water horizontal portion extending from the hot water vertical portion to the outlet channel, and the cold water intermediate channel is L-shaped as including a cold water vertical portion and a cold water horizontal portion extending from the cold water vertical portion to the outlet channel.

10. The waterway assembly of claim 9, wherein the hot water vertical portion is defined by the hot water body, the hot water horizontal portion is defined by the central body, the cold water vertical portion is defined by the cold water body, and the cold water horizontal portion is defined by the central body.

11. The waterway assembly of claim 10, further comprising a hot water inlet channel defined by the hot water body and extending parallel to the hot water vertical portion of the hot water intermediate channel, and a cold water inlet channel defined by the cold water body and extending parallel to the cold water vertical portion of the cold water intermediate channel.
