I'm installing a new pedestal sink. How close to the wall do I cut the copper supply stub outs? I would like to make it as attractive as possible by coming close to the wall, but don't want to burn down the house in the process.

Thanks - Dennis

You can cut it so that your fitting will be practically at the line of the wall. The trick will be to use a shield against the wall when soldering it... like this:

If the drywall isn't up yet, I would solder a male pipe adapter on almost flush with where it will be and screw a chrome angle stop directly on to it. If you already have a copper tube coming through the wall, it is going to be tricky soldering a pipe adapter on to it close to the wall. You might look at the epoxy made for joining copper pipe. You could even slip the adapter into the wall around the tubing.
