Woodford RK-17VB Vacuum Breaker Float Kit – 4 Pack | Irrigation Backflow Prevention

Overview

The Woodford RK-17VB Vacuum Breaker Float Kit is designed to help guard outdoor water lines against backflow in irrigation and sprinkler systems. This 4-pack gives you flexible protection for multiple zones or future projects, making it a practical addition to a DIY or pro installation.

With a compact, rugged profile, the RK-17VB is built to stand up to outdoor conditions. The float-based mechanism engages as pressure shifts, helping to regulate flow and reduce the chance of unwanted reverse flow. The result is a discreet component that integrates cleanly with typical line fittings without adding excessive bulk.

What’s included and compatibility

This pack contains four RK-17VB vacuum breaker float kits, ready for installation in compatible irrigation lines. No specialized tools are required for standard fittings, and the compact design makes it easy to position alongside existing components.

For best results, pair these kits with your current Woodford components and follow your system’s guidelines for flow direction and mounting. The RK-17VB is designed to work smoothly within typical residential irrigation configurations.

Installation tips (quick guidance)

Start with the water off and relieve pressure. Align the kit with the indicated flow direction, then connect with appropriate fittings. Hand-tighten first, then snug with a wrench for a final seal. Check for leaks after re-pressurizing the line.
