I'm in the process of replacing a bathroom vanity, and in order to get it flush against the wall I need to trim back one of the water supply pipes which sticks out too far (pic attached). Plan to replace the shut off valve in the process. As my handle indicates, I'm a newbie at this stuff, but it seems like this is a relatively easy fix. Can I just trim the pipe by a half inch or so using a pipe cutter of some sort? And do I need to do anything to the pipe in order to seat the new valve properly (remove burrs, clean threads)? If soldering is the way to go, then I'll need to bring a plumber in.
thanks for your assistance.
