More progress today. I found a panel that had two leak points in it. I haven't done much sweating of pipe, but I managed to get them sealed up.
How it was.
Cleaned up and ready for flux.
Yay, no more leaks.
I also had this one to fix up. Cleaning it out was a pain. I used a file and sand paper to clean the area. It took a while and two attempts, but its sealed now.
