Leaking galvanized thread
Last night we discovered a leak in the dry walled ceiling of our basement. Luckily we caught it early. The leak is coming from the thread of what I suspect is our water supply line.
Question, with the entire ceiling being dry walled (house was flipped before we bought) are there any viable solutions to either temporarily or permanently repairing the leak without tearing out large sections of walls and/or pipe. I was thinking maybe hydraulic cement might work, or cutting out the bad section and then use the existing elbow. I would cut out about a six inch section and re-thread the long piece and putting a coupling in. My plumbing experience is rather limited to replacing faucets and a little PVC work, but since this is most likely a supply line and therefore pressurized, I am a bit leery of patches.
Any advice is welcome.
