How To Solder Copper Pipe Leak

Can you solder a copper pipe with water in it?

Don’t try to solder pipes with water in them. Soldering a joint in pipes that contain even tiny amounts of water is nearly impossible. Most of the heat from the torch goes into turning the water to steam, so the copper won’t get hot enough to melt the solder. Stop the trickle of water with a pipe plug.

Can you repair a hole in copper pipe with solder?
