Watts 887223 First Check Rubber Kit 6 Inches 909 LF909

Product Description

The WATTS 887223 is a first check rubber repair kit designed for use with WATTS 909 and LF909 series reduced pressure zone backflow preventers in the 6-inch size. This kit supplies the rubber seating and sealing components needed to restore the first check valve assembly to proper working condition. Backflow preventers require periodic maintenance to maintain certification compliance, and having the correct OEM-style rubber components on hand keeps service intervals on schedule. Licensed plumbers and cross-connection control specialists are the typical installers for this type of repair kit.

This kit is suited for commercial and industrial plumbing installations where 6-inch WATTS 909 or LF909 reduced pressure zone assemblies are in service. These assemblies are commonly found in irrigation systems, fire suppression supply lines, and building water service entry points where backflow protection is required by code. The rubber components in this kit address wear and deterioration of the first check seat and disc that occur over time under normal operating conditions.

Installation Notes

Installation and repair of reduced pressure zone backflow preventers should be performed by a licensed plumber or a certified backflow prevention assembly tester in accordance with local plumbing codes and ASSE standards. Shut off the upstream isolation valve and relieve system pressure before disassembling the check valve module. Do not overtighten or damage rubber seating components during reassembly. After repair, the assembly must be tested by a qualified tester before being returned to service.
