The Ames 2000SS backflow preventer model is a double check assembly. Production began in 1990. The body is fabricated stainless steel. Single top mounted cover. All have a modular check design. The 3/4"-2" from 1990-1992, had internal check mechanisms that were modular and made of a glass filled Noryl. The older assemblies have ball valve shutoffs that were built into the body. In 1992 external ball valves that screw onto the body of the assembly were added. In 1992 the check module working mechanism design was changed to a pivot design. 3/4" - 2" discontinued in 1997. The 2 1/2 - 12" check mechanism is made of a glass filled Noryl. The checks are modular. The check design is a cam operated mechanism. 2 1/2" - 10" sizes the check modules are not repairable and the whole check module must be replaced.
