I lied, another question. This home improvement stuff is harder than it looks.
I soldered 8 joints in 3/4" pipe Tuesday. I looked it over today and there was a drop of water on the pipe. It took a while, but I found one of the joints was oozing a drop of water about every 5 minutes. I know the pipe is well seated in the joint because I did this one with the T in a vise and shoved it in securely; but I am very unhappy with it leaking. I heated the fitting from the bottom and applied the solder to the top of the pipe. It wicked into the pipe and ran out the bottom, leaving a little glob. Oddly, the leak is at the bottom where the solder actually ran out. I cleaned like crazy, and surely flux would have run to the bottom even I failed to flux adequately; and that is where I was heating the joint so it had to have been hot enough (since the top was hot enough to melt the solder), so I can't figure out what I could have done wrong. Even with a magnifying glass I can't see anything that isn't solid, but there obviously is. If I wasn't so anal, I wouldn't even have seen the damn drop.
Could I have heated it too much and the solder ran out before it could harden?!
So, my question.... Since I know the pipe is well seated, and I can see a continuous band of solder all the way around the joint, it can't be too bad, right? If I heat the bead of solder that is on the pipe right next to the leak, I think maybe there is a possibility (probably not large) that it will stop the leak. If that happens, can I let it go? Or is the joint comprimised and simply stopping the leak is masking a potential failure.
Opening up the joint and redoing it will not be easy because I will have do a bunch of dissassembly down below. There is a water powered sump pump and I will have to pull that out before so I can run water through the pipe to be sure no loose solder has fallen into the pipe. So, if I can avoid that... But a joint failure will be a horrible mess, and I have to be sure it is sound.
I am going on vacation Saturday, so you won't have to put up with my questions for a while. I am NOT taking my laptop.
