Watts 887905 Rubber Repair Kit 709 LF709 2000CIV 2.5-3 in

Product Description

The WATTS 887905 is a rubber repair kit designed for rebuilding and servicing backflow preventer assemblies. The kit supplies replacement elastomeric components that restore proper check valve and pressure-reducing function within the assembly. It is sized for 2.5 inch and 3 inch valve bodies, covering the 709, LF709, and 2000CIV product families. Licensed plumbers and backflow prevention specialists typically perform this work as part of scheduled maintenance or post-inspection repair. At 0.5 pounds, the kit is compact and straightforward to stage on the job.

This kit applies to commercial and residential plumbing systems where reduced-pressure or double-check backflow prevention is required. It is used when annual test-and-repair procedures reveal worn or failing internal rubber components such as check discs, o-rings, or seat seals. The 887905 is appropriate for valve bodies in the 2.5 inch to 3 inch size range across the covered valve series.
