Specification

A Reduced Pressure Zone Assembly shall be installed at each

potential health hazard location to prevent backflow due to back-

siphonage and/or backpressure. The assembly shall consist of an

internal pressure differential relief valve located in a zone between

two positive seating check modules with captured springs and

silicone seat discs. Seats and seat discs shall be replaceable

in both check modules and the relief valve. There shall be no

threads or screws in the waterway exposed to line fluids. Service

of all internal components shall be through a single access

bronze cover secured with stainless steel bolts. The assembly

shall also include two resilient seated isolation valves, four resilient

seated test cocks, and an air gap drain fitting. The assembly shall

meet the requirements of USC; ASSE Std. 1013; AWWA Std.
