The Spühlkasten is over 15 years old, so I was skeptical about whether there is an outlet for such an old box. But Geberit offer fortunately to a valve which is likely to fit into almost any model.
The delivery was very quick. The old valve carefully removed and connected the new, I could hardly believe that I was done after only 15 minutes and the toilet worked flawlessly again. Madness! Top product and a great solution for older wearing parts! Should be no problem for lending to carry out the change.
