Hiya Folks, Ok, I've sweated my share of copper before but have a question. I recently worked on repairing a water line (3/4" Cu) and all but two of the fittings are water tight. The two fittings that seem to be weeping ever so slightly, were where I tied into existing lines. These lines had been buried so it took a while to get them all cleaned up. They looked pretty darned shiny to me when I soldered them but I suppose there was pit or dirt in there somewhere. Anyway, my question is this, can I re-solder the existing fittings? Can I simply heat them up (no water in the lines) and flow more solder in or do I need to cut them out and put new in. I suspect I know the answer but thought I'd ask anyway. Cheers, cc
