Kohler 84499 Conversion Kit

The Kohler 84499 conversion kit supplies a complete set of internal replacement parts for older one-piece toilets made by Kohler. It includes a ball cock, flapper, flush valve and the necessary gaskets to refresh the flushing mechanism. Professional plumbers and homeowners use this kit to restore reliable operation without replacing the entire fixture. The kit targets the specific components that commonly wear out in these legacy designs.

Replaces worn tank internals

This kit replaces the original ball cock, flapper and flush valve assemblies that degrade over time in older one-piece models. The jump is worth it when the toilet runs continuously, flushes weakly or leaks between the tank and bowl due to hardened seals. Installing the kit restores the designed flush volume and stops water waste. It is not suited for two-piece toilets or newer one-piece models that use different valve geometries.

Limits of the ball-cock design

The included ball cock operates on a float-arm mechanism that requires adequate water pressure to shut off cleanly. In very low-pressure supplies the valve may not seal completely, leading to ongoing seepage. The flapper size and hinge geometry are fixed for the original Kohler flush-valve seat, so the kit cannot adapt to aftermarket tanks or universal retrofit valves. Buyers needing a pressure-assisted or dual-flush upgrade must choose a different system.
