When sweating copper joints - say when you are sweating something not attached in a wall, but making something up before installing it, after you sweat a joint is it okay to dunk it in water to cool it off or do you have to let it cool slowly by itself?
I know you can run the heat up a joint by cooling something off and see the hardened soldier liquify for a second, is their any danger of weakening a joint by dunking it and cooling it off instantly?
