This is a leak in an old joint between a copper sink drain and lead toilet soil pipe. The connection was done by soldering the copper sink drain into the side of the lead pipe. It's a terrible connection that I've managed to limp along using some quick-drying material from the hardware store. I know, I know, the best thing to do would be to replace the flange at the toilet, cut back the cast iron pipe a few feet back and replace everything with PVC. But that's going to be expensive and take a long time (I'll have to remove a new toilet from the bathroom above to put in a new flange.) So . . . any materials I could use to plug the leak good enough? I tried re-soldering it, but it was too dirty to take. It's in an accessible enough place to fix if it every happens to leak again. Many thanks. Bob
