I recently replaced a water heater and put a 1/2" male -> pex transition into a Tee that supplies my water heater. The problem is this: no matter what I do, the transition keeps leaking! I have tried cleaning it out with a wire brush, using pipe thread tape, using heavier pipe thread tape, and using a combination of pipe thread tape smeared with teflon infused thread sealant.
It continues to leak, though it's so slow, I can't even really see it happen. The fitting is tight and I'm running out of options. Has anyone ever dealt with something like this? Any help you might provide is appreciated!
Thanks in advance!
