Hi, I can’t get one cartridge to budge when trying to replace in a mixer tap. The hot side cartridge was tight but removed with wrench comfortably, but cold side is so tight Ive burred the nut on the cartridge. Any advice on how else to remove the cartridge without damaging the mixer tap is greatly appreciated.

For future reference, you’re best off with a ring spanner or a socket as they grip all the way around the nut .

Now it’s mullered you are best off with a self tightening wrench which will grip well, but will usually cause a bit of damage. A great version of this is the good old stilsons - just go as big as you need….give up at 48” and just buy a new tap.
