Geberit dual flush and basin mechanism type 240 | Ref 136.906.21.2 | Porcelain cistern

Hi, it's Stan!
This mechanism with its Geberit type 240 basin , reference 136.906.21.2 double flush, has changed color. Before, it was white and green, now it is black and blue. It was designed for porcelain toilet cisterns.

Its height adjustment allows it to adapt to all tank heights. You can also adjust the consumption of the small and large flushes.

My advice

If you have the old generation of the white and green mechanism (visible in my photos), you can interchange it and clip it onto the old basin (which avoids having to dismantle the tank).

Improve your maintenance

Also replace your float valve with the new generation of the Geberit type 380 float valve

By purchasing from my store, you reward my advice and content, thank you 🫶
