DESCRIPTION
The Apollo® Model DCDA4SG, DCDA4SGN Double Check Detector Assembly is designed to prevent contamination of the potable water supply due to back-siphonage or backpressure from substances that are non-health hazards. The device consists of a mainline double check valve with a by-pass line. The by-pass consists of a water meter and an approved Apollo® double-check valve with Apollo® ball valves as shut-offs. The by-pass serves to measure water use of up to 3 gpm. Grooved connections on an epoxy-coated ductile iron body allow for easy connection to butterfly valves or gate valves. Note: Model DCDA4SG replaces Model 4S-600 (also known as Model DCDA) in all sizes except 10”.
