Ok, here's the situation. I winterized my gf's house last year, and like a dumbass I didnt unhook the swamp cooler water line(in my defense I always had central air). Anyway.. the line ended up splitting in the attic, and when I went to turn the cooler on it leaked.

Ok, here is the dilema. The copper tube is 1/4" inch. Its the soft tube, and because it froze and ended up bursting the pipe itself seems to have expanded. I cut the split area out, and I bought some supplies to splice some new 1/4" tubing in.. but the old tubing is now larger/bulged.

Is there anything I can do other than cutting a hole in the damn wall where the pipe didnt freeze, and is still 1/4" diameter?

Are you sure that it's 1/4"? Maybe it's 3/8"? The best thing is to go from one end to the other with a new line. Put a tee in the middle with a valve so that you could drain it before the winter.

Yea the pipe is 1/4". It has a thing to drain it downstairs, but I never un hooked it. What I did since the PSI on it is so low, I got some rubber tubing, and replaced the section I cut out by sliding it over the ends and using hose clamps.
