American Plumbing Partsmaster 980137 Ballcock Flapper Kit

Product Description

The AMERICAN PLUMBING PARTSMASTER 980137 is a ballcock and flapper repair kit designed to restore proper fill and flush function in Kohler toilet tanks. This packaged kit provides the two core components most often replaced during a toilet rebuild: the ballcock fill valve, which controls water intake after each flush, and the flapper, which seals the flush valve seat to prevent tank leaks and phantom cycling. Licensed plumbers and experienced DIYers install this type of kit as a cost-effective alternative to replacing individual components separately.

This kit is suited for residential toilet tank repair applications. It addresses two of the most common causes of running toilets: a worn or degraded flapper that allows water to seep past the flush valve seat, and a failing ballcock that either runs continuously or fails to refill the tank to the proper level. The packaged format reduces service call time by combining both parts in a single unit.

Key Features

• Includes both ballcock fill valve and flapper in one packaged kit
• Targets the two most common causes of continuously running toilets
• Designed as a replacement fit for Kohler toilet tank configurations
• Packaged format simplifies parts sourcing for service calls
• Suitable for residential toilet tank repair and rebuild work

Compatibility

Designed as a replacement-style ballcock and flapper kit for Kohler toilet tanks. Consult the kit contents and Kohler model documentation to confirm fitment before installation, as toilet tank configurations vary by model series.

Installation Notes

A licensed plumber or qualified DIYer typically performs this repair. Before beginning, shut off the water supply at the angle stop valve below the toilet and flush to drain the tank. Follow all applicable local plumbing codes, including IPC guidelines, when servicing toilet fill and flush valve assemblies. Do not overtighten supply line connections or ballcock locknuts, as toilet tank porcelain can crack under excess force.
