Wattstopper 98268459067 Rpz Check Valve Kit 1-1/4 in

Product Description

The WATTSTOPPER 98268459067 is a reduced pressure zone (RPZ) check valve rubber repair kit sized for 1-1/4 inch assemblies. This kit supplies the internal rubber components needed to restore an RPZ backflow preventer to proper working condition. RPZ assemblies are a critical line of defense against backflow contamination in potable water systems, and worn or damaged internal check components are a common cause of assembly failure or test non-compliance. This repair kit is designed to replace the rubber seating and sealing elements inside the check valve module without requiring full assembly replacement.

This kit is intended for use in commercial and residential plumbing systems where 1-1/4 inch to 2 inch RPZ backflow preventers are installed. Typical applications include irrigation systems, boiler feed lines, and any cross-connection control installation requiring periodic maintenance or post-inspection repair. The kit is lead-free compliant, making it suitable for potable water service in jurisdictions that enforce low-lead plumbing standards.

Installation Notes

Follow local plumbing code requirements, including IPC and applicable cross-connection control regulations, for testing and reinstallation after repair. Do not reassemble with worn or damaged rubber components from the original kit.
