Hi everyone,
I redid some plumbing in my basement and it went well except for one thing:
I can NOT get one area to stop dripping. It's a spot in a hot water line to the shower where I joined 1/2 inch CPVC to 1/2 inch copper. I used a male, threaded CPVC fitting into a female, threaded copper fitting. I used pipe dope and tightened it as much as I could. Any more tight and it probably would break.
I have redone this fitting three times and it just won't seal, always drips. As I said, I used pipe dope one time. One time I used teflon tape. I was told that both of these are ok to use in this situation.
Now, oddly enough, when I take a shower and the pipe gets good and hot, it stops dripping. When it cools, it starts again as if the expansion was sealing it.
I'm out of ideas.
Help?
Thanks
