So in the process of removing out shower/tub enclosure we cut a piece of pipe going in the shower head. It is covered with rubber and looks to be copper. How do I fix it? Is it a job that we can do or does it need a plumber? Thanks!

Sounds like a 1/2" shower raiser that's been covered with Armoflex Insulation. Simply purchase a 1/2" Sharkbite coupling,(see coupling on left hand side) from your hardware store and connect the two ends. This is a solderless connection. Good luck, Tom
