Sunbelt Marketing 4476-01-02 00:00:00 Compression Stop Waste

Product Description

The SUNBELT MARKETING 4476-01-02 00:00:00 is a 1/2 inch compression stop and waste valve used to shut off water supply lines and drain residual water from the downstream piping. This type of valve is a standard component in residential and light commercial plumbing systems, typically installed on branch lines supplying fixtures or outdoor hose bibs. The side waste port allows the installer to drain trapped water from the line after shutoff, making it a preferred choice for freeze-protection applications in cold-climate installations. Licensed plumbers and pipefitters are the primary installers of this fitting.

This valve is suited for residential and light commercial cold-water supply lines where both shutoff and drainage capability are needed in a single fitting. Common applications include irrigation shutoffs, outdoor hose bib supply lines, and branch supply isolations in areas subject to freezing temperatures. The compression connection style eliminates the need for soldering, making it adaptable to copper tubing without open-flame tools.

Key Features

• Compression connection on a 1/2 inch port for tool-accessible, solder-free installation
• Integrated waste port allows downstream line drainage after shutoff
• Suitable for freeze-protection plumbing configurations
• Compact valve body fits tight spaces in rough-in plumbing scenarios

Compatibility

Designed as an OEM-style replacement or standard-fit component for 1/2 inch compression-connection plumbing systems in residential and light commercial water supply applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and the International Plumbing Code (IPC). Shut off the main water supply and relieve line pressure before removing or installing any valve. Compression fittings require proper tube preparation — deburr and square-cut the tubing end before seating the ferrule. Do not overtighten the compression nut, as doing so can deform the ferrule and cause leaks.
