The 2-1/2” – 12” Double Check Detector Assembly shall be an Apollo Model DCDALF 4A or DCDA2LF 4A. The assembly shall be manufactured in America and carry a 5-year Apollo factory warranty. The TriForce™ 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 (2-1/2” – 6”) or SS studs & nuts (8” – 12”). Access to the check valves shall be by an Apollo quick-connect SS coupling (2-1/2” – 6”) or grooved couplings (8” – 12”). The bodies shall be domestic SS in 22-1/2” – 8” sizes and FDA epoxy-coated ductile iron in 10” & 12” sizes. The assembly consists of a mainline double check valve with a Type 2 bypass (Type 1 optional) consisting of a lead free* single check (SCV) and meter bypassing the mainline second check to prevent backflow while accurately measuring all flows up to 2 gpm while the mainline 2nd check remains closed. Assemblies with the optional Type 1 bypass consist of a lead free* double check valve and meter which bypass both mainline checks and accurately meter all flows up to 2 gpm with the mainline checks closed. The Apollo lead free* ball valve test cocks shall have SS handles. 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 backpressure from substances that are non-health hazards.
