I have a threaded water connection (brass into brass) with a tiny leak. It won't even make a drip over several hours, but when I rub my finger on the bottom side, I can feel and see the water that was there. I don't want to close up the wall with it this way, and I also don't want to undo the connection (lots of work and I don't want to disturb the rest of it for fear of worse problems).
I have tried Seal-All, but it remains pliable and bubbles from the leak. I have tried PermaGasket (from my car repair kit) but it's too soft...the water comes on through. I have tried a tape that resembles electrical tape, but you stretch it and then it recovers to make a tight "seal", but the water still eventually comes through.
I have considered turning off the water, draining the section, drying it thoroughly, and applying some epoxy, but before doing this, it occurred to me that you guys may know the perfect solution.
What would you do?
