All good advice, that is filling the tubes. I didn’t mention it because the metal is expensive but there is Cero-bend, a low melt (160*F) bismuth alloy that is intended for just such jobs. The problem that I see is the thin wall and the relatively large diameter, not sure if even the cero-bend would work with out cracking the tube. You could try the pitch (would be much cheaper). Hard pitch is what the commercial roofers use on built up roofs. The stuff comes in big paper wrapped cylindrical blocks, gets broken up with an ax and melted in a fired pitch tank. Go find a roofing contractor that does hot pitch built up roofs… he should give you a small chunk.

PS, freezing water will burst the tube
