I am in the process of replacing the 40mm cartridge in a Bristan basin mixer tap. I successfully removed the lever then the shroud and the nut underneath. But the cartridge would not lift out. I used a bit of persuasion with a pair of grips then it suddenly come out - well sort of. It came out in 4 bits leaving a white plastic piece at the bottom of the tap which will not shift.
Limescale buildup is all I can think of. I am going away for a couple of weeks and putting some lime scale remover around it. Hopefully it will loosen it. It should just lift out, shouldn't it?
Anybody have any other ideas?
