4 The assembly shall consist of a main line valve body composed of two (2) independently acting approved clapper style check modules with replaceable seats and disc rubbers. Servicing of both check modules does not require any special tools and are accessed through independent top entry covers. This assembly shall be fitted with approved UL/FM inlet/outlet resilient seated shutoff valves and contain four (4) properly located resilient seated test cocks as specified by AWWA Standard C511. The auxiliary bypass line contains a 5 8" x 3 4" Water Meter that complies with ANSI/AWWA Standard C700 coupled with an approved check assembly compliant to AWWA Standard C511. The bypass line is designed to detect leaks or unauthorized Water usage of the Water system while protecting against possible backpressure and backsiphonage conditions for high hazard ( , toxic) applications.

9 * Indicates nominal dimensions with OSY Gate Valves (Full Open Position)** Indicates weight of complete Backflow Assemblies with specified Gate ValvesThe gap drain is not designed to catch the maximum discharge possible from the relief valve. The installation of the FEBCO air gap with the drain line terminating above a floor drain will handle any normal discharge or nuisance spitting through the relief valve. However, floor drain size may need to be designed to prevent Water damange caused by a catastrophic failure condition.
