The Watts 1" Series 009 Reduced Pressure Zone (RPZ) backflow preventer assembly is a commercial-tier mechanical barrier designed to protect municipal potable water grids from health-hazard cross-connections. Perfect for containment lines at service entrances, industrial processing loops, firelines, and large irrigation mainlines, this compact assembly isolates systemic backpressure and backsiphonage before contaminants can enter clean drinking supply channels.

Advanced Cross-Connection Fluid Control:

  • Dual Independent Check Modules: Houses two localized, positive-seating inline check valves utilizing captured spring architectures and replaceable silicone seats, ensuring zero internal bypass leaking under varying line pressures.
  • Hydraulic Differential Relief Valve: Integrated intermediate relief zone automatically vents safely to an approved drain link if an internal check pressure variance is detected, eliminating health-hazard cross-contamination risks.
  • Streamlined Single-Access Top Cover: The modular interior core layout can be completely maintained inline through a single, accessible top cover, allowing quick annual inspector certifications and seal cleanings without decoupling the main piping structure.

Complete Assembly Standard: Fully equipped out of the box with dual quarter-turn, full-port resilient seated ball valve shutoffs with tee handles, and four integrated top-mounted test cocks for field differential gauge testing.
