Abstract
A backflow preventer assembly includes a housing, a first mounting assembly configured for assembling by insertion with a first end of the housing, and a second mounting assembly configured for assembling by insertion with a second end of the housing. The housing and mounting assemblies include through bores in fluid communication. Securing material secures opposed surfaces of the first mounting assembly and the housing, and opposed surfaces of the second mounting assembly and the housing. Plating material is located on the inner surfaces of the housing and mounting assemblies. The plating material forms a wall restricting migration of the securing material into the housing and mounting assembly bores. Ball valves and check valves are attached to the mounting assemblies. The housing wall defines a port providing access to the check valves.
