Dripping bathroom mixer tap, how to replace washer?

[Dave86]

Evening all

Looking for some advise on this pretty straightforward question (hopefully!) - this is the bathroom mixer tap, which is dripping slowly - however as it doesn't have any caps on the tap ends, nor any visible screw(s) how do you go about taking the taps off to replace the washers? Or is it a different model that relies on a different method to replace the washers? They're about 10 years old but not sure on the make

Thanks for any help!

¼ turn ceramic cartridge? Only turns ¼ of a turn then stops. That's how you know


Looks like a Allen key hole in your pictures that will release the x top.

The taps looks scaled up too, so may find it difficult to get the heads off once you remove the allan key grub screw.

Soak the heads in limescale remover.
