Damixa mixer tap leaks

[SecretPrawn]

Hi,

I wonder if anyone can help? have a Damixa Jupiter tap (https://damixa.com/kitchen-mixer-33-p1406) which is constantly leaking from under the mixing handle.

I had thought it was the cylinder, so have replaced this. However I am getting a constant drip bubbling up from the cylinder, then running down the side (see pictures).

I've put some videos of the problem here:

Would anyone have any advice on what to try next?

Thank you for any thoughts!

Tom

Was there a seal on the bottom of the cartridge? Is it seated correctly?

Is the mating face of the tap clean, 1 small piece of crud will stop it sealing correctly.

Was the new cartridge identical to the old one
