piping questions

My weekend project is to remove a bathroom shower and install a new one in a different location. The plan is to have all the plumbing ready for a Monday inspection.

I've got the drain roughed in and am ready to install the shower hot and cold water supplies. I have a couple of questions ..

Is there a rule of thumb about spacing between hot and cold water supplies in a stud wall? I'm using 1/2" copper pipe and if I run the pipes close together I can avoid demo of a tiled wall. I can space the pipes about 3" apart. The run is about 3'-4'. I plan on insulating the pipes.

What is preferred for making up threaded pipe fittings, teflon tape or pipe joint compound?

Spacing: Your fine...especially if your insulating. Even if your not 3" in between is still fine.

Threaded fittings: For a metal on metal in the wall...i'd go with teflon. Personally? I use both...Teflon first..then dope over it...plus the lubrication from the dope helps when tightening it.
