VACVBKX1B Vacuum Breaker Kit, for Anti-Siphon Frost-Free Sillcock Valves, 4 Pack

Vacuum Breaker Kit for Anti-Siphon Frost-Free Sillcock Valves

This vacuum breaker kit replaces the anti-siphon assembly on frost-free sillcock valves, restoring backflow protection so outdoor hose bibs meet code and stop contaminated water from siphoning into the supply line.

Overview

This vacuum breaker kit is a repair part for anti-siphon frost-free sillcock valves used on outdoor hose bibs. The assembly mounts on the valve outlet and breaks the vacuum that can pull standing water backward into the household plumbing. It suits homeowners and plumbers fixing a leaking or missing breaker cap without replacing the entire sillcock.

Good To Know

Q: Will this fit my outdoor faucet? A: It is made for anti-siphon frost-free sillcock valves with a standard breaker port. Confirm the thread size and valve style before ordering.

Q: Why does a sillcock need a vacuum breaker? A: The breaker stops water in a hose or attached fixture from siphoning back into your drinking water supply. Many plumbing codes require one on every outdoor hose bib.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
