Watts RK919T-100 Rpz Total Repair Kit 1-1/4 and 1-1/2 Inch

Product Description

The WATTS RK919T-100 is a total repair kit for 1-1/4 inch and 1-1/2 inch 919-series reduced pressure zone (RPZ) backflow prevention assemblies. It provides all the internal components needed to fully restore a worn or failing RPZ assembly to service without replacing the entire valve body. The kit includes a first check repair kit, a second check repair kit, and a relief valve repair kit. All components are genuine OEM parts, ensuring proper fit and function within the 919-series assembly. Licensed plumbers and backflow prevention specialists use this kit during scheduled testing cycles or following a failed backflow test.

This repair kit is intended for 1-1/4 inch and 1-1/2 inch WATTS 919-series reduced pressure zone assemblies installed in commercial and residential potable water systems where backflow protection is required. It is commonly used during annual backflow preventer certification testing and repair, or whenever internal wear, fouling, or seat damage is identified during inspection. The kit eliminates the need to source individual check and relief valve components separately.

• Fits both 1-1/4 inch and 1-1/2 inch valve sizes with one kit

Installation Notes

Installation should be performed by a licensed plumber or certified backflow prevention technician in accordance with local plumbing codes and AWWA guidelines. Isolate the assembly using the upstream and downstream shutoff valves and relieve system pressure before disassembly. Inspect all seating surfaces for damage prior to installing new components, and verify proper operation with a differential pressure test gauge after reassembly.
