How To Desolder Copper Pipes And Fittings

Today I will teach you how to desolder or unsolder copper pipe and fittings. This process is useful for fixing a leak in a soldered joint, or replacing an old fitting without cutting the pipe.

Thanks for video, showing the actual sweating time, without cutting away.

Question. Can I put a compression shutoff valve in place of the old soldered on valve? I'm wondering if the thin coating of solder left behind would cause a compression valve to not seal properly.

That's easy because you're a mile away from an elbow or coupler. How do you desodler a valve if you have an elbow a half of inch away and not melt the pipe at the elbow? Thanks.
