Geberit dual flush and basin mechanism | Ref 240.559.00.1 | For Twinline 8 UP170 concealed toilet

Hello, it's Stan!
This mechanism with Geberit basin , reference 240.559.00.1 , is the latest generation of Geberit (the 2nd exactly). If you look at the mechanism, at the top, you have the adjustment of the small flush which has the shape of a blue tab that can be slid from right to left and, lower down, in a blue circle, the adjustment of the large flush (you will receive the water consumption by e-mail). It is installed in the Twinline 8 UP170 double flush concealed cistern
