Then I used Rectorseal teflon pipe seal, still leaked. So I thought maybe I have a defective pipe. So I got a new one,put it in, same thing, still leaks. Any ideas? I'm ready to put 5 minute Epoxy on this thing if i can't stop this leak. tape isn't generally used to make it seal, but to make it slippery so yo can tighten it some more. they make a sealant putty for this.

Lowes has a teflon sealer that is a white thick liquid in a can with a brush. Can sized about like the pvc glue. Works pretty well for me in these situations.
