How to Solder Copper Pipe

Soldering a copper pipe is relatively easy. Knowing how to solder copper pipe allows a do-it-yourselfer to install pipe yourself. A properly soldered joint will last for years (in many cases decades).

Soldering copper pipe isn’t difficult, but it takes practice. Mastering a perfectly soldered copper joint takes a bit of practice. Be patient! Your first couple of attempts may not look beautiful, but soon you’ll be soldering copper that not only doesn’t leak but also looks good.

1

Clean the pipe with a wire brush.

Clean it to bare metal.

2

Apply flux paste.

The flux paste ensures a clean surface for the solder.

3

Use a handheld propane torch to heat the fitting.

Just don't get it so hot that you can't hold it any more.

4

Melt the solder so that it flows into and fills the joint.

Finally, using a soldering iron, melt the solder so that it flows into and fills the joint between the pipe and the fitting.
