Zurn RK114-350 Repair Kit 350 Series 1-1/4 to 2 Inches

Product Description

The ZURN RK114-350 is a complete repair kit designed for the Wilkins 350 series reduced-pressure zone (RPZ) backflow preventer assemblies. This kit includes replacement check valve components and O-rings needed to restore proper sealing and operation during scheduled maintenance or after a failed test. Sized for 1-1/4 inches through 2 inches valve bodies, it provides the critical internal components to bring an RPZ assembly back into compliance without replacing the full valve. Licensed plumbers and backflow prevention specialists perform this type of service during annual testing cycles or following a repair call.

This kit is applicable to commercial and residential plumbing systems where a Wilkins 350 series RPZ backflow preventer is installed to protect potable water supply from contamination. Typical install scenarios include irrigation systems, fire suppression connections, and general commercial water service lines. The 1-1/4 inch to 2 inch size range covers mid-size valve bodies commonly found in light commercial and industrial applications. Use of OEM-matched repair kits is standard practice to maintain device certification and ensure proper seating of checks and seals.

Installation Notes

Installation should be performed by a licensed plumber or certified backflow prevention tester in accordance with local plumbing codes and IPC guidelines. Shut off the upstream water supply and relieve pressure from the assembly before disassembling the valve body. Inspect the valve internals for wear or debris before installing new checks and O-rings. Follow the valve manufacturer's service instructions for correct component orientation and seat seating to ensure the assembly passes post-repair backflow testing.
