Watts 887152 Rubber Repair Kit 709 909 Backflow 3/4-1 in

Product Description

The WATTS 887152 is a complete check valve rubber repair kit covering both check valves in compatible 709 and 909 series backflow preventers sized 3/4 inch through 1 inch. The kit supplies all rubber seating and sealing components needed to restore check valve function without replacing the entire assembly. It is designed for licensed plumbers and backflow prevention specialists performing scheduled maintenance or field repairs on reduced-pressure and double-check backflow preventer assemblies. Keeping genuine rubber components on hand reduces downtime during annual testing and inspection cycles.

This repair kit applies to residential and light commercial plumbing installations where 709 or 909 series WATTS backflow preventers in the 3/4 inch to 1 inch size range are installed. Typical applications include potable water supply lines, irrigation system connections, and other cross-connection control points subject to local backflow testing requirements. The kit covers both check valves in a single package, making it suitable for a full rebuild during a service call.
