4 IN SS Reduced Pressure Detector Backflow Preventer Assembly, Maxim, Grooved Butterfly Shutoffs, Link Check Modules, Less Meter, N Pattern
This Maxim(TM) 4 inch reduced pressure detector 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 backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. It is ideal for protection at cross-connections identified as health hazards such as on fire sprinkler systems and from other contaminants found at the service line entrance. This compact modular design with a single access cover for easy maintenance, without a meter, is approved for horizontal N pattern installation. It consists of a stainless steel body with a quick access sleeve, torsion spring check valves, grooved butterfly valve shutoffs, test cocks, and a corrosive resistant bottom mounted pressure relief valve.
