I just pressurized the supply in my new house. All the PEX is tight and dry, but the threaded connections are leaking, as usual. For each fixture, I used a drop-ear elbow with a threaded pipe nipple and a stop valve. Out of 11 such fittings, 4 of them leak where the stop valve connects to the pipe nipple. It seems like in recent years, I've had more and more trouble getting pipe fittings to seal- poor imported quality, I would guess.
Any recommendations for a better seal? I've tried teflon tape, both regular and extra thick. I've tried several kinds of teflon pipe dope. Any ideas before I glue the fittings with some kind of epoxy??
