I just replaced my hot water tank, and had to make a couple of changes in the plumbing, i.e. lengthening a piece of pipe, etc. Somehow, I've developed a weaping leak in a sweated joint nowhere near where I was working. Any suggestions as to how I might stop it without having to drain all the lines, and re-solder the joint. I hate soldering with a passion, and there are two elbow joints within inches of each other, so with my luck if I get one fixed another will start.
Tks
You really have to replace the fitting with the leaking joint. Next time, remember to clean, clean, clean with emory cloth. Then flux. Heat the joint where you want the solder to run into, not where you will apply the solder. Do all the joints in the area at the same time so the heat doesn't destroy your preparations. Wipe the joints with a slightly damp rag after soldering.
That was the problem with this leak, all the soldering was done on threaded fittings that were screwed into place after being soldered elsewhere. There was no soldering done anywhere near the new leak.
