Good Morning All, My shower setup has 2 knobs (cold and hot) and the head. I have no idea what brand these knobs are; the house was built in the 40's and God knows how old they are. The rest of the bathroom is very outdated so I'm assuming they weren't replaced any time too recently. The cold temp knob has a leak, but I'm not sure how to remove the knob. There is no cap on these knobs - it kind of looks like a cap, but it is not removable. I can unscrew the fat base behind the knob, but I can't remove completely since I can't figure how to get the knob off. I'm including some images for reference. Please let me know if you have any advice here and thank you in advance! Once I get the knob off, I may need some advice on fixing the leak, but I'll start with just trying to remove it first so I can see what's going on back there.

We are installing a new vanity in our basement half bath. The drain for the existing sink comes from side wall which is 90 degrees from the wall where the water lines are located. The good news is I have total access behind both walls. The new vanity will not allow the existing drain hookup. Is it within code and possible to hook up the new drain thru the same wall as the water lines (normal position) and run the plumbing around the wall to the sewer line and attach to it. Total run around the wall would be about 3-4 feet.
