M200: 2 1/2", 3", 4", 6", 8", 10"
M200A: 2 1/2", 3", 4"
This is a double check 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 M200 and M200A. The "M" designation refers to Ames Maxim brand name. The body is constructed of stainless steel tubing. To access the check components a movable sleeve is mounted over the access cover. On the 6"-10" sizes the sleeve is attached by two grooved couplings. The check components are modular and constructed of noryl plastic. The check utilizes a torsion spring which is contained when the check module is removed from the body. The check spring must be extended and controlled with a pin or screwdriver to replace the check disc. The check disc may be either an EPDM or silicone rubber. The M200 and M200A will have the same external dimensions. The "A" model was discontinued in 2008 and utilizes a bi-link check mechanism while the "non-A" version utilizes a tri-link check mechanism. The body length dimensions may be up to 1" shorter than shown in the dimension chart on versions produced in 2003 or earlier. The body dimension does not change the repair parts inside.
Common repair parts are a very small subset of the 10,000 plus items BAVCO stocks.
