Speakman G05-0672 Vacuum Breaker Check Assembly

Product Description

The SPEAKMAN G05-0672 is a vacuum breaker check assembly designed to prevent backflow and protect potable water systems from contamination through back-siphonage. This assembly integrates a check valve with a vacuum breaker to maintain one-way flow and vent the line when pressure drops. It is typically installed at fixture supply points, emergency equipment, or other outlets where backflow prevention is required by plumbing code. Licensed plumbers and facility maintenance technicians install this type of assembly during new construction, retrofit projects, and compliance-driven upgrades.

This vacuum breaker check assembly is suited for use in commercial and residential plumbing applications where atmospheric vacuum breakers or check-type backflow preventers are specified. Typical installations include safety shower and eyewash stations, hose bibs, and similar outlet connections that require backflow protection per applicable plumbing codes. It is intended for cold or tepid water supply lines in low-pressure service conditions.

Key Features

• Combines vacuum breaker and check valve function in a single assembly
• Prevents back-siphonage and backflow contamination in potable water systems
• Designed for straightforward inline installation at fixture supply connections

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes governing backflow prevention devices. Shut off the water supply and relieve line pressure before removing or installing the assembly. Do not install downstream of a shutoff valve in a configuration that would defeat the vacuum breaker function. Inspect sealing surfaces and threads for damage before making final connections.
