Backflow Protection For Hose Connection Points

Hose bibb vacuum breakers are designed to prevent backsiphonage at hose connection outlets where there is a risk of contaminated water being drawn back into the potable supply. Installed directly onto sillcocks and hose bibbs, they act as a protective barrier during negative pressure events, helping safeguard drinking water systems from cross-connection hazards.

These devices are intended for non-continuous pressure applications, meaning they operate effectively where the downstream shut-off valve is closed after use. Suitable for residential and light commercial settings, they provide a straightforward method of fixture-level backflow protection without requiring complex piping modifications.

At Dutco Tennant LLC, we deliver this solution to support plumbing systems that require practical, code-aligned protection at outdoor taps and service hose connections.
