metal to pvc: leak help please
I'm attaching a 1" threaded pvc pipe (male) to a 1" threaded metal pressure vacuum breaker backflow preveter (female) for an irrigation system. I'm getting a small drip leak where these thread together. I used teflon tape but probably only 2-3 turns of tape on the threads...Do you think I put to little tape on? I bought some of the thicker pink tape and plan to do 4-5 wraps at least. Also, how tight should I tighten the threads? I hand tightened last time and didn't use wrenches so as not to distort or break the pvc.
Thanks for any help you can give!
