SPECIFICATIONSThe 2 ½” – 12” Reduced Pressure Detector Assembly shall be an Apollo® Model RPDALF4A or RPDA2LF4A. The assembly shall be manufactured in America and carry a 5-year Apollo® factory warranty. The TriForceTM center-stem guided check valves shall feature reversible silicone rubber seat discs. The check valves shall be held in place by SS snap-in retainers (2 ½” – 6”) or SS studs & nuts (8” – 12”). Access to the check valves and relief valve internals shall be by an Apollo® quick-connect SS coupling (2 ½” – 6”) or grooved couplings (covers) and SS bolts (relief valves) (8” – 12”). The bodies shall be SS in 2 ½” – 8” sizes and FDA epoxy-coated ductile iron in 10” & 12” sizes. The assembly is a mainline RP with a Type 2 bypass consisting of a lead free* single check valve (SCV) and meter bypassing the mainline second check to prevent backflow while accurately measuring all flows up to 2 gpm with the mainline 2nd check remaining closed. Assemblies with the optional Type 1 bypass consist of a lead free* RP and meter which bypasses both mainline checks and accurately meters all flows up to 2 gpm with both mainline checks closed. The Apollo® domestic ball valve test cocks shall have SS handles. Both RP relief valves shall be positioned at the bottom of their respective assemblies with separate center-access covers. The pressure drop across the assembly shall be documented by an independent laboratory. The assembly shall prevent contamination of the potable water supply due to back-siphonage or back pressure from substances that are health or non-health hazards.
