I've got a pin hole leak in a copper pipe on my hot water heat sytem.

Murphy is my partner. So, of course, the leak is right where the pipe
goes through the floor and you can't get at it.

So, cut the pipe below, lift out the radiator and the bad section,
work on it at sawhorse height, then lower the new work into the
hole and make the final join below. Hoisting the radiator is the
only hard part. If quarters underneath are cramped, it might pay to
use those push-on coupler gizmos (sharkbite, I think).
