This is a double check assembly. Production began in 1998. In 1997 the Watts Company purchased the Ames Company. Watts began marketing the Ames 2000SS as the Watts 774 and the 2000SE as the 774X. The body is made of stainless steel. The model utilizes a modular check design so that springs will be contained when the cover is removed. The check mechanism threads into the body and is a cam operated design made of glass filled noryl. In the
2 1/2"-6" size the check assemblies are not field repairable and the whole check module must be replaced for an average repair. The difference between the 774 and 774X is that the 774X utilizes internal parts one size smaller than the pipe size: (e.g. an 8" 774X would contain 6" check modules, a 6" 774X would contain 4" check modules). Be sure which version you have because parts will be different. The 774X models were discontinued in 2006. The 8"-10" check does have a rubber disc that is field replaceable.
Common repair parts are a very small subset of the 10,000 plus items BAVCO stocks.
