If your Franke Triflow Kubus Tap is dripping from the Spout then you need to replace the valves.

Your Franke Triflow Kubus Tap or Franke Filterflow Kubus Tap takes 3 valves (1 hot and 2 cold).  The Triflow version was discontinued Spring 2011 and replaced by the Filterflow version.  They have different parts.

Triflow or Filterflow ? It is easy check which version you have:

The Triflow valve has 20 Splines and only one set of threads below the black rubber O Ring, whereas the Filterflow valve has 28 Splines and two sets of threads, one above the black rubber O Ring and one below it.

If your Tap is leaking from the Hot side then usually replacing the hot valve will solve this. It is a little bit trickier if your Tap is dripping from the cold side – which is dripping – filtered cold or mains cold or both ?

If you don’t know whether is is the Mains Cold OR Filtered Cold valve that needs replacing (or both?) you could buy 2 cold, try one (same one) in mains first and if still dripping then switch the new valve into the filtered side and if still dripping then chances are both mains and filtered are dripping (reason why I am advising to try the ONE new valve in both mains and filtered is because once you fit one of our valves then you cannot return it – whereas you can return any unused valve for a refund).

The triflow version was discontinued spring 2011.

    My Franke Kubus tap is dripping from the spout. I guess I will need to replace the valves but am not sure how to get at them as there is not a grub screw holding the handle end in place. Do I just unscrew the lever and pull?

      Hi John, which Franke Kubus do you have ? the Triflow version or the standard version? There should be a screw to undo the handle to get at the valve. This blog post should help you :
