compression fittings

I recently installed a shut-off valve to my shower water supply. I used a compression fitting. The fitting leaks on one end which I believe is because the pipe is not quite a straight shot to the fitting.

Questions is, is it o.k. to now solder on top of the compression fitting or do I need to use a different valve?

A compression fitting needs to be on the pipe just right, or as you've seen, it will leak.
A pro plumber would never do this (I'm not one, so I have no just do whatever works for me). I simply smear a little clear silicone caulk on the ferrule ring before tightening on the nut.
Seals it every time.
Good luck!

I would try the Old Guy's idea (I've got pride but I'm not a plumber ). If that doesn't work or you don't feel comfortable doing it, don't solder over the compression fitting you are asking for more problems. You have to many differant types of metal there to get a good solder joint going.
I would remove the valve, cut the pipe (neat and straight), install a new ferral. Install the shut off and hope for the best.
