Watts 0887182 Rubber Parts

When you are performing field service on a Watts Series 009 Reduced Pressure Zone (RPZ) backflow preventer, the Watts 0887182 (RK 009-RT 3/4-1) is the essential service kit required to restore the assembly's hydraulic integrity. This Total Rubber Parts Kit is specifically engineered for 3/4 inch and 1 inch 009 series assemblies, including the M1 and M2 configurations. The kit contains the critical diaphragm, two check valve disc assemblies, and all necessary O-rings for the stem, cover, and seat. Using genuine Watts replacement parts ensures that the relief valve and check modules maintain their precise differential pressure settings, preventing nuisance dripping and ensuring the assembly passes its annual backflow preventer testing. Whether you are dealing with a fouled first check or a weeping relief valve, this comprehensive kit allows for a full top-to-bottom rubber refresh without needing to source individual components. This kit replaces legacy part number 887182 and is the standard for commercial and residential backflow repair.
