AMES 4000SS 2 1/2-4" REPAIR KIT

Contains: Check Assys, Disc, Diaph & O'Rings. This is an original manufacturer repair product used within various divisions of the Watts Water Technology Company (Ames, Febco, Watts)

Model Overview

This is a reduced pressure assembly. Production began in 1990. The 2 1/2" and 3" end to end body dimension could vary by 5/8" due to a manufacturing design change of the end flanges. Repair parts will be the same for both versions. The check mechanism on the 2 1/2"-12" is made of glass filled noryl. The checks are modular in construction so that springs will be contained and seats are replaceable. The check design is a cam operated mechanism. In the 2 1/2"-6" sizes the check modules are not field repairable and the whole check module must be replaced for a proper repair. The 8" and 10" check does have a rubber disc that is field replaceable. The relief is mounted under the check body and mounted by an external relief valve sensing line.
