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

Your Olympus Triflow or FilterFlow tap takes 3 valves (1 hot and 2 cold).  You need to know whether you have the ‘Triflow’ version or the ‘Filterflow’ version because these two taps take completely different parts.  If you have the Triflow version, then your handles have a blue, red or green dot on each of the top of the Handles.  If you have the Filterflow version, then the letter H, C or F is etched onto top of the handle instead of the colour. 

If your Olympus Tap is leaking from the Hot side then usually replacing the hot valve will solve this. It is a little bit trickier if your Olympus Tap is dripping from the cold side – which is dripping – filtered cold or mains cold or both ? Ideally you or your Plumber should isolate the water feeds in turn to establish conclusively which Valve needs replacing.

  1. 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).
  2. The other issue is for you to establish is whether or not you have the Triflow version or the Filter Flow version of this tap as both look identical.

* Easiest way to establish whether you have the Triflow version or FilterFlow version: Triflow has 20 splines on the valve.  FilterFlow version has 28 splines e

The Triflow version was discontinued spring 2011.

Valve Measurements:

Overall Height:  53mm

Franke Olympus FilterFlow 1427R-H, 1427R-C x 2 (for cold and filtered cold)

Valve Details:

This Valve has two sets of threads: One Set ABOVE the Black O Ring and One Set BELOW. But when you look in detail at this Valve, please ensure that you also look at the images of the Valve inside the bush, as this can then look ‘wider’ than a normal valve.

Nut Height: 8, Splines: 28, Overall height: 53mm, Diameter at thread: 21mm

1427R Valve and Brass Bush

1427R Valve and Brass Bush. The Valve should come out of Tap with no Brass Bush surrounding it. If the Brass Bush is stuck to the Valve and you can’t separate, then you will need to also replace the Brass Bush.

Again the same cold is used in both i.e… 1427-C is used in the mains cold and another 1427R-C is used in the filtered cold.


If your tap is dripping where the spout meets the base then you need to replace the O Ring Kit

Use the information above to see which Tap it is.


Here is the complete list of all the Franke Triflow and FilterFlow Taps. It might be useful to compare your Tap to the images contained within this blog as customers occasionally mistake which Tap they have, and different taps require different spare parts.
