Watts 7013281 Check Valve O-ring 6 Inch 2000SS 3000SS

Product Description

The WATTS 7013281 is a second cam check o-ring designed as a replacement seal component for large-diameter backflow preventer assemblies. This o-ring provides a critical sealing function within the check valve mechanism, preventing fluid bypass and maintaining system integrity under line pressure. It is installed by licensed plumbers and backflow prevention specialists working on commercial and industrial water systems. The 7013281 fits specific WATTS valve series and is a direct OEM-style replacement part intended to restore proper check valve operation during scheduled maintenance or after seal failure.

This o-ring is applicable to WATTS 2000SS and 3000SS series assemblies in 6-inch configurations, as well as 8-inch SE series backflow preventers. These valve assemblies are commonly found in commercial plumbing systems, irrigation mains, fire suppression supply lines, and industrial process water applications where backflow protection is required by code. Replacement of cam check o-rings is a standard part of annual backflow preventer inspection and rebuild procedures performed by certified backflow assembly testers.

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or certified backflow assembly tester in accordance with local plumbing codes and the applicable requirements of the Uniform Plumbing Code or International Plumbing Code. Shut off the upstream water supply and relieve system pressure completely before disassembling the valve body to access the cam check components. Inspect the seating surfaces for wear or damage before installing the new o-ring, and do not reuse a compressed or deformed o-ring. Refer to the WATTS service manual for the specific valve assembly to confirm correct o-ring placement and reassembly sequence.
