Geberit Type 290-380 Dual Flush Toilet | Ref: 283.307.21.2 | Porcelain Cisterns

Hello, it's Stan!
This dual flush mechanism with type 290 basin and type 380 float valve Geberit reference 283.307.21.2 is the highest quality on the market!

Compatibility
Geberit designed it for porcelain toilet cisterns with a lid hole between 12 mm and 38 mm, or between 40 mm and 50 mm. Its height adjustment allows it to adapt to all cistern heights. You can also adjust the consumption of the large and small flushes, which saves water. As for the float valve, it comes with accessories that allow you to fix it in your cistern and connect it to the stopcock using a high-quality blue seal.

If you have the older generation of Geberit mechanism, type 280 or type 250 Geberit , you can interchange it and clip it onto the old basin remaining at the bottom of the cistern. (which avoids having to dismantle the cistern).
