I just remodeled my bathroom and when the tile guy put in the new tile, he just put backer board behind the tile. Originally there used to be backer board and drywall. Now when I’m trying to install the spigot it doesn’t sit flush to the wall and the handle that turns the water on and off doesn’t sit flush to the faceplate anymore. I bought new fixtures and they are Moen which is what I had before. I think the problem is I now have about a half inch extra space. The copper pipe is 3 1/2 inches long where the spigot goes. Is it possible to cut the pipe without harming the plumbing and if so, how do I do it? And how can I fix the handle so it is closer to the faceplate for the on/off of the water. It works, just looks stupid so far from the wall.
