Review: Good price, easy to fit and works perfectly, but is it genuine Geberit? - Good price, easy to fit, and works perfectly. I probably only needed to replace the internal cup washer that had a small tear. Anyway, I fitted the new unit, then descaled the original and replaced its internal cup washer so now I have a spare. It looks like a genuine Geberit part, and the quality seems very good. However. the cardboard box in which it was delivered does not have the usual Geberit markings and the label indicates it is from China. So, I am unsure if it is a genuine Geberit part or a copy. Whichever, it works.
