I have 3/4" copper pipe outdoors (backyard, above ground), and I am adding a couple tee fittings to branch to a different area. I am having a hell of a time getting the solder to melt. My next move is to skip solder and use sharkbite (expensive). Any ideas on why this is so difficult? Even if the pipe I'm working is removed from the system (thus, absolutely no water inside) still no luck.
- I don't know the age of the pipe.
- I'm using
- Benzomatic propane (not mapp).
- Benzomatic lead free plumbing silver bearing solid wire solder
- Benzomatic lead free plumbing water soluble plumbing flux
- The old pipes are green (oxidation), but I clean the joints with wire brush.
- Fittings are brand new.
Edit: Yes, I'm heating the pipe joint and (trying) to apply solder on opposite side of heat. My first solder attempt a year ago was successful, main difference is indoor vs outdoor.
