The risk of starting fire to something flammable inside the wall is too
great for me to suggest doing that, so don't try it.


Nooooooooo, don't even think about it.

Recently had to replace a section of tubing with a hole. Unsweating the
exposed end caused enough heat blasting through the 1/8" hole on the other
end to start the stud on fire. It ran right up the wall to the firestop.
Caught it quick but the potential was there for a serious house fire.
