This is a double check detector assembly. This model was produced under the Hunter name from 2000-2002. In 2002 Watts bought the Hunter models and began production as the Ames C300 and C300A. The C300A model was discontinued in 2008. Watts will produce these models under the Watts name as the model 757 DCDA or 757A DCDA. The "C" designation refers to Ames Colt brand name. The mainline assembly is similar in construction to the C200 and C200A. The bypass assembly used for the first two years was the Flomatic DCVE 3/4".
