Hose Bibb Vacuum Breaker | Lead-Free, Solid Brass

Designed for use on yard hydrants, and hose bibbs to prevent back siphoning of contamination in the potable water supply. Installation provides protection of potential health risks and contamination in potable water. Comes complete with a breaking set screw. Once tightened set screw will break off to prevent tampering and removal.

**Once the back-flow preventer is installed with the factory screws, it cannot be removed. We recommend the #SS20 Stainless Steel Removable Locking Screws. This item allows back-flow preventers to be removed for service of the hose bibb, yet remain tamper-proof.
