WTS 957 2.5-4" TOTAL REPAIR KIT EPDM

Model Overview

This is a reduced pressure assembly. This model was produced under the name Hunter from 2000-2002. In 2002 Watts bought the Hunter models and began production as the model 957. This model will also be sold as an Ames model C400. The body is constructed of stainless steel tubing. To access the check components a movable sleeve is mounted over the access cover. On the 2 1/2"-6" size the sleeve slides over the body to access the check components. On the 8"-10" size 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 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. The relief valve body attaches to the outside of the check body and is pressurized with an external RV sensing line.
