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?
Copper pipes are much different. The most advanced pinhole leak fix involves cutting the pipe in half. But rather than a compression fitting, the plumber will use a solder fitting for the most secure repair. The pipe must be cleaned and free from the water first or else the soldering won’t work.

Can epoxy be used on copper pipe?
Epoxy pipe lining is an increasingly attractive option for copper pipe pinhole repair because it both solves and prevents problems. By coating the inside of copper pipe, copper epoxy seals pinholes and blocks the corrosive action of elements in water so that no new pinholes develop.
