This 4 IN lead-free reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to back-siphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance. This assembly consists of a short lay length lightweight stainless steel body, resilient seated outside stem and yoke shut-off valves, test cocks, corrosive resistant stainless steel bottom mounted relief valve, and a patented cam-check assembly.
