Question:
What is the “correct” or “right” way to thread a PVC male threaded adapter to a Copper Female threaded adapter, and how or what do you use for sealant?
Answer:
I would wrap the male adapter with teflon tape 6 or 7 times and then apply a teflon based pipe dope on top of the tape. Carefully thread the male adapter into the female fitting until it is hand tight. Now use a wrench or channel locks and give it a couple of turns. Wipe of the excess pipe dope and turn on the water to test for leaks.
