I cut a 1/2" copper pipe to insert a tee fitting a which will eventually go to a Pex line for an outdoor tap. The copper pipe was vertical, and when I completed the cut I found that the pipe was actually under tension. The top half of the pipe moved, and now the pipes are not exactly in a straight line. I can still position the two halves in a fitting, but each pipe wants to force the fitting in a different direction. Let's say the bottom one is basically plumb but the top half wants to rest at about 10 degrees from vertical. I hesitate to solder it in this position. Can I still get a good seal when I have to force the pipes to work with the fitting?
I can't change either pipe -- they are close to the main shutoff valve. I also don't want to introduce a pressure drop for the whole house by replacing the section with Pex. (Really wish the house had 3/4" pipes.) I was able to patch it up with Sharkbite for now. Sharkbite is more tolerant of the pipes not being plumb than an inflexible copper fitting.
Should I try to bend the top pipe to force it to be vertically? Is there a safe way to do this copper? Or maybe I would be better off cutting the top pipe in a second place and soldering another fitting to get a better match?
