When you solder a copper pipe, you’re actually joining two pieces of metal by melting a filler metal (solder) between them. The molten solder displaces any air in the joint, and when it cools, it forms a solid bond. A leak in a brazed joint can be caused by many things: an improper fit-up, dirty or rusty surfaces, an insufficient amount of flux, or simply poor soldering technique. But whatever the cause, there are several steps

How To Fix A Leaking Brazed Joint
