Woodford 271986 Brass Vacuum Breaker

Product Description

The WOODFORD 271986 is a brass vacuum breaker designed to prevent backflow by stopping siphonage from reversing the flow of water into a potable supply line. When downstream pressure drops below atmospheric pressure, the breaker opens to introduce air and break the vacuum, protecting the drinking water system from contamination. This type of device is a standard component in hose bibb and outdoor faucet assemblies, and is typically installed or serviced by licensed plumbers during new construction, renovation, or fixture replacement work.

The WOODFORD 271986 is suited for use on outdoor hose bibbs, wall hydrants, and similar non-pressurized outlet applications where cross-connection control is required by plumbing code. Its brass construction makes it appropriate for both residential and light commercial plumbing systems where durability and corrosion resistance are priorities.

Key Features

• Brass construction provides corrosion resistance for long service life in outdoor and wet environments
• Prevents backflow via vacuum-breaking action, protecting potable water supply lines
• Designed for hose bibb and wall hydrant applications requiring cross-connection control
• Compact form factor allows installation in space-constrained locations

Compatibility

Designed as an OEM-style replacement vacuum breaker for hose bibbs, wall hydrants, and similar outdoor plumbing fixtures requiring cross-connection protection.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing codes and IPC cross-connection control requirements. Shut off the water supply and relieve line pressure before removing the existing vacuum breaker. Ensure threads are clean and use appropriate thread sealant compatible with potable water systems. Do not over-tighten brass fittings, as this can crack the body or damage seating surfaces.
