The approval of backflow prevention assemblies should include not only compliance with the Uniform Statewide Building Code, but also acceptance by the University of Southern California Foundation for Cross-Connection Control and Hydraulic Research (USC-FCCCHR). USC is the only organization that tests backflow assemblies under both laboratory and field conditions before granting their approval. Approval is based upon several criteria in addition to performance, including size, configuration, and flow orientation.
My recommended wording for this Section would be as follows: "Any backflow prevention assembly or device or backflow elimination method shall be in compliance with the USBC, and be approved by the University of Southern California Foundation for Cross-Connection Control and Hydraulic Research".
