Here are the 3 main causes as to why your Franke Mythos Tap dripping :

1. Franke Mythos Tap dripping from the Spout

If your Franke Mythos Tap is dripping from the spout then it is most likely that you need to change the valves (one or both), and / or the brass bush ring, (but usually its just the valve) hot or cold.

2. Franke Mythos Tap dripping where Spout meets Base

If your Franke Mythos Tap is dripping where the spout meets the base then it is most likely that you need to replace the O Rings.

3. Franke Mythos Tap leaking from the handle:

The valve may need tightening or replacing. Here is our Guide How to remove the Handle on your Kitchen Tap. See also blueprint below showing where the grub screw etc are on your Tap to enable you to remove your handle and valve.

If the valve bush comes out with the valve, order a new set of valve and valve-bush.

If you have replaced the valve just remember that new valves can take a few days for the rubber washer to “be bed down”. Tighten the valve and if leak continues after tightening please contact us on sales@tapsandsinksonline.co.uk.

Valve Details:

Please note when buying the Valves that the Hot and Cold valves are NOT interchangeable.

Franke Mythos Tap Valve

Mythos Tap Dripping from the Spout

Earlier installation guides refer to the valve 2552R. Then later ones refer to the Valve 1427R. Then in 2014 the Franke Mythos Tap Valve was changed by manufacturer from the 1427R Valve to the SP3547. While the 2552R and the 1427R are the exact same valve (two threaded valve, just a name change of valve) the later valve is different in appearance as it has only one thread. For our own stock purposes to ensure that the correct valve is picked by our shippers, we refer to the earlier valves as 4276R i.e. you will see it noted as 4276R (2552R/1427R). Your installation guide will tell you exactly which part to order. However, if you don’t have your installation guide then we would recommend that you purchase the earlier 4276R (2552R / 1427R) valve with two threads as it has a slighly larger seal to the later one threaded SP3547 .

We have provided here measurements and images of both valves for reference if you don’t have your installation guide as otherwise you might receive a valve that looks different from your own valve, when you remove it, and think that you were sent the WRONG valve. Please all see below regarding the Brass Bush Part when you remove your own valve.

Brass Bush still attached to Valve:

If your valve appears to be wider than ours but all measurements tally except diameter, just make sure that you have removed the brass bush.
