I have to remove a faucet cartridge and I can't seem to figure out how to do it. The outer chrome ring doesn't seem to unscrew, and there is no space to fit a wrench to get to the nut.
Do I need a special tool or am I missing something?
Edit: I finally got it after spraying some WD40 on there. It is only the rounded chrome part that unscrews, definitely not easy to get a grip on a rounded part like that, I had to use a rubber band.
