Watts 909-CK2 Second Check Valve Repair Kit bathware

Watts 909-CK2 repair kit for LF909 valves

This kit is a genuine Watts second check valve repair kit designed for LF909 series valves in the 2-1/2 in to 3 in range. It provides the specific internal components required to service the second check mechanism. Professional plumbers and facility maintenance teams use it to restore proper backflow prevention function.

Replaces worn internal check valve components

The kit replaces the cover O-ring, disc assembly, spring assembly and supplies lubricant for reassembly. The jump is worth it when the existing second check valve shows signs of leakage, fouling or failed spring tension that compromises the backflow assembly. It addresses the specific wear points without replacing the entire valve body.

NSF Lead Free compliant kit for 2-1/2 to 3 in valves

The included parts comfortably handle the service demands of LF909 series assemblies within the stated size range. It runs out when the valve body itself is damaged, corroded or when the first check valve or relief valve components require attention, as those parts are not included in this second check specific kit.
