Franke Mythos Tap Dripping – Identify the Problem and Fix It
If your Franke Mythos kitchen tap is dripping, this guide will help you identify the cause and choose the correct genuine parts to fix it.
We’ve been supplying genuine Franke spare parts to UK customers for over 40 years. All advice below is based on our in-house technical experience — this content is original and written by our team.
What’s Causing the Drip?
1. Drip from the Spout
Usually caused by worn valves. You may need to replace one or both (hot and cold). Occasionally, the brass bush ring may also need replacing.
2. Leak Where the Spout Meets the Base
This is normally due to worn O-rings, which seal the base of the spout. Replacing them is straightforward and we stock the correct Franke O-ring kit.
3. Leak from the Handle
This is often caused by a loose or worn valve. Try tightening the valve — if the leak persists, a replacement is likely needed.
If the brass bush comes out with the valve when removed, you will need to replace it. Also note: new valves may take a few days for the rubber washer to bed in — you may need to retighten after a few uses.
Which Valve Does Your Mythos Tap Use?
The Franke Mythos tap has used two different valves over time:
- 4276R (also known as 2552R / 1427R): Two-threaded valve, thicker white seal
- SP3547: Single-threaded valve introduced in 2014
If you’re unsure, we usually recommend the earlier 4276R. It works in all models and has a slightly larger seal for better performance.

Basic Comparison
- 4276R – 2 threads, nut height 8mm, spline height 10mm
- SP3547 – 1 thread, nut height 6mm, spline height 11mm
All measurements rounded to the nearest mm.
Check for a Brass Bush
Sometimes when you remove your valve, the brass bush comes out still attached. This makes your removed valve appear wider than the new one, but it’s just the bush adding diameter.

How to remove mythlos Handel
There is a grub screw on the underside of the handle (underneath) which you need to unscrew with an Allen key and then remove the handle. Be careful not to lose your grub screw as they are very small.
Also here is our Guide how to remove the handle on your kitchen tap that has a video at the end as well to further assist.
