Features

The Geberit 2-inch replacement dual flush valve provides an official, upgraded solution designed to seamlessly replace older, discontinued white flush valves in Kohler and Duravit toilet cisterns. Manufactured by Geberit as the direct successor to MPN 236.402.21.1 (Typ230), this modern dark grey valve is fully interchangeable with your original setup, allowing you to swap out the mechanism without even removing the cistern from the pan. Furthermore, it comes complete with a stylish chrome ABS dual flush push button, giving you a water-saving half-flush and a full flush option. Because it is engineered to exact factory tolerances with a standard 2-inch outlet, it restores reliable, leak-free flushing performance instantly.

Details

A failing or leaking toilet flush valve can lead to constant water trickling down the pan, weak flushes, and rapidly escalating water bills. Moreover, replacing proprietary valves in modern Kohler or Duravit toilets often seems like a nightmare if you think you have to dismantle the entire ceramic cistern from the wall or bowl.

Fortunately, this genuine Geberit 2-inch replacement valve solves the problem completely. Because its modern dark grey body is fully interchangeable with the older white version and drops straight into your existing base without unbolting the cistern, the repair is remarkably straightforward. Consequently, you achieve a watertight, high-performance dual-flush system with minimal effort and maximum reliability.
