The Geberit 290 flush valve is the replacement for the highly popular Twico 1 and Twico 2 valves. It will fit straight onto the same basket as these two outlet valves making it a simple replacement. It will also fit numerous other 'close coupled' (cistern sits on top of the pan) suites as it can be adjusted in several directions. This high quality Swiss valve will give years of trouble free maintenance and is extremely easy to adjust for flush volumes. It is supplied with a dual flush button (shown).
To install and adjust the valve, please watch the following video and note that the half and full flush buttons push down together until the end of the stroke when the half flush travels a little further to give a different volume.
I would also recommend watching this video before fitting or adjusting to prevent making a mistake which can be annoying:
Remember, when replacing the flush valve, it is a good idea to also replace the inlet valve. These items have a similar lifespan and you don't want to be doing this job twice. Have a look at our inlet valves, they are probably much cheaper than you expect.
(Look under “Inlet Valves” on the blue ribbon above)
Also, for adjustment of your valve, have a look at our page explaining how they work. This will give a good idea of how to adjust them. Start with the single flush valves and then read about the dual flush valves.
Toilet manufacturers rarely make parts which look the same but are slightly different. Check the photos and dimensions and if it looks identical then it probably is.
