This 2-1/2 in stainless steel reduced pressure zone assembly is designed to prevent the reverse flow of contaminated water from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. This extremely compact and lighter than a traditional designed assembly is approved for horizontal installation in accordance with the direction of the flow arrow. 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 stainless steel body with a quick access sleeve, torsion spring check valves, resilient seated gate valves with non-rising stem, test cocks, and a corrosive-resistant stainless steel bottom mounted pressure relief valve.
