Re-soldering a copper sweat fitting
Posted by Rick Rufini on May 22, 19100 at 15:20:32:
After sweating all the copper connections on a new tub/shower control I discovered a leak when I turned the water back on. I drained the water out of the lines again, cleaned the area with steel wool as best I could, put more flux on the fitting and reheated it. I was able to re-sweat it and stop the leak. While the leak is stopped for now I'm concerned that over time it may leak again. With the water back on the system is under pressure so I'll watch for a few days before I close up the wall. What are your thoughts?

Is there a better way to re-solder a connection? How do I know if enough solder got in and around the fitting?

Thanks for your advice,
