Watts 888569 Rubber Repair Kit 775 Series 1 Inch

Product Description

The WATTS 888569 is a rubber repair kit designed for use with the Watts 775 series backflow preventer at the 1-inch valve size. This kit supplies the internal rubber components needed to restore proper sealing and check valve function within the assembly. Plumbers and mechanical contractors use kits like this to service backflow preventers in place, avoiding the cost of full valve replacement. The kit is a lightweight service part, weighing 0.4 pounds, and is sized specifically for the 1-inch 775 series body.

The 888569 is used in commercial and residential plumbing systems where 775 series reduced-pressure zone or double-check backflow preventers require periodic maintenance or repair. Annual testing and periodic rebuilding of backflow preventers is standard practice in most jurisdictions, and rubber internals are a common wear item. This kit supports in-field rebuilds performed by licensed plumbers or certified backflow assembly testers during scheduled service intervals.
