Can't Remove Tap Cartridge

[pulmicort1415]

Trying to remove tap cartridge from mixer tap.

Can't budge it even though no corrosion round it.

Have soaked it in WD40. No joy. Scared of doing damage

May we ask what brand

How much of the tap head have you been able to remove? A photo of the tap would help in giving advice. When I had a monoblock basin tap with a slow leak I couldn't even get the handle/lever off (after undoing the grub screw). Had to buy a complete replacement and even then getting the old one apart (out of interest) took some time.

Try heat, boiling water at first, it may make the larger part swell enough to loosen it's hold.

If you are in a hard-water area, it's probably limescale in the thread.

The modern style mixer taps that I have experience of look like this:
