Piston Activated Frost Proof Self-Draining 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. This self-draining Lead Free hose bibb vacuum breaker will automatically drain when the hose is disconnected from valve outlet. This is accomplished when the hose is disconnected, by causing a spring loaded plunger to spring forward off the seat, thereby allowing drainage of the valve and yard hydrant outlet. Air is now allowed in the hydrant to allow drainage and freeze protection. Draining protects the valve from freezing and rupturing in cold weather. Comes complete with a breaking set screw. Once tightened set screw will break off to prevent tampering and removal. Please note that once secured the hose bibb vacuum breaker will not be able to be removed without force by any individual.

Slow shipping

I paid a good amount for shipping to come in a week so I ended up paying more than the part itself costs. As soon as I got a confirmation that it shipped out the arrival date changed to a week later.. so I’m the end the price wasn’t worth it.

Hi Mimi, thank you for your review! We really appreciate the feedback we receive. Unfortunately, shipments going to Canada are typically pretty expensive. It looks like UPS Standard was selected for the shipping option at checkout, which would be regular ground shipping. We are also on the east coast here in the United States, so the shipping time seems about correct for the distance it had to travel. We do apologize for the inconvenience.

No more dribble

Our garden hose would always dribble water. The hard water buildup was interfering with the anti-siphon mechanism. This part corrected the problem. Great for Minessota winters
