Thanks. The loop will do the far side just fine, but I'm worried about
the top and close sides. I'm a fanatic about proper preparation before
soldering!

I have a 3/4" Cu pipe carrying return water in my baseboard heating

exposed about 4" of length and am pondering sawing the pipe. But
there is no room to sand it all the way around. There is only about
1/2" of space.

Can anyone tell me how to get the pipe prepared for soldering? TIA


Not nearly enough info, but you could make a loop of
"sandpaper" out of maybe a 2" wide strip.
Form the loop so that it looks like a "U" and slip
one end under the pipe. Work the sandpaper up and down.

If not that, then you'll have to make a better picture
of what you're doing.

Probably why yours don't leak at the onset or a week/month(s) later.
