I want to renew the caulk, surrounding the flange, the one that is adjacent to the wall. Is there a way to loosen the flange, or it comes along with the taps? I'm not sure how to do it, and I'm afraid to break the things.
UPDATE
So I've removed the handle, but then I don't know how to remove the stem. I can actually rotate the flange around, meaning that stem and flange is one "component". Am I supposed to pull out the stem, or rotate? I tried carefully rotate it clock-unwise, it didn't help, neither did pulling out.
OK, now I unscrewed the large white nut behind the stem, but the stem still doesn't badge, and it doesn't seem I can unscrew it either :
