I live in a 60 year old house and most of the piping is probably original. We have a finished basement where most of the piping is hidden. Today we developed a leak between one of the 3/4"galvanized pipes and the T-junction it's attached to on a supply line. I pulled down the paneling to expose the problem area, but have not yet pulled down all the other sections to see where this pipe ends.

It's a relatively slow drip and I tried to use epoxy putty to fix it... I had the main water valve turned off in order to stop the dripping, emptied the lines, dried off the pipe, applied the epoxy, waited 3 hours before turning the water back on, and still drip,drip, drip...

Is there any easy fix I can do ? Should I re-try the epoxy ? It appears that there is some sort of corrosion around the joint, which could be residue from dried up water (?) as I can't really tell how long this might have been leaking...

I really don't want to have to do more demo to find the end of this one pipe if I don't have to (I'm thinking if I could get to both ends, maybe then I un-do the connections at both ends and then reconnect with fresh joint compound... but they are old pipes and I don't want to mess around too much with them if I don't have to)

Since the epoxy didn't work, would some sort of solder be better ? Or maybe I try the epoxy again ? Or any other ideas ?

How far is the leak from the T-junction ?

The leak is right where the 1"pipe goes into the T-junction

May be if you can reach all around the pipe , then the best is to warp it by using fiber glass wetted with epoxy minimum 3 layers of warping , starting from solid area to solid area to guarantee that the weak area is in the middle , allow enough time for the epoxy to set (best 24 hours) - good luck
