Product Details

The Toto THU123 is a replacement valve cap assembly designed for Toto ballcock fill valves. This genuine OEM component includes the diaphragm assembly that controls water flow and shutoff in the toilet tank fill valve mechanism.

Key Features:

  • Genuine Toto replacement part ensuring proper fit and function
  • Includes diaphragm assembly for ballcock valve operation
  • Designed to restore proper fill valve performance
  • Helps resolve issues with continuous running or slow tank filling
  • Direct replacement for worn or damaged valve cap assemblies

This valve cap assembly is an essential component for maintaining efficient toilet operation. Over time, the diaphragm can wear out, causing fill valve problems such as continuous water flow or inadequate shutoff. Replacing this component can restore your Toto toilet to proper working condition.
