I need to remove a soldered valve from a supply line and there is a soldered elbow only about 2 inches away.
I've read another post about trying to keep the second joint cool but it sounded less than convincing.
It's the first branch in the house so if I mess up I'll have no water until I can fix it.
Am I wasting my time trying to keep it cool or should I just open up the wall so I can deal with the elbow right away?
