Product Description

The WATTS 887185 is a complete rubber rebuild kit designed for servicing 009 and LF009 series reduced-pressure zone backflow preventers in the 1.25 to 2 inch size range. The kit includes the elastomeric internal components needed to restore proper check valve and relief valve function during scheduled maintenance or after a failed field test. Licensed plumbers and backflow prevention specialists use this kit to return assemblies to service without replacing the entire valve body.

This rebuild kit is intended for use on WATTS 009 and LF009 series reduced-pressure zone backflow preventer assemblies sized from 1.25 inches through 2 inches. It is suited for commercial and residential plumbing systems where backflow protection is required by code, including potable water, irrigation, and fire line applications where the 009 or LF009 assembly is already installed.

Installation Notes

Installation should be performed by a licensed plumber or certified backflow prevention tester in accordance with local plumbing codes and IPC requirements. Shut off the upstream and downstream isolation valves and relieve system pressure before disassembling the backflow preventer.
