I've just redone one bathroom and found that the nipple between the

this was not kosher and replaced it with a galvanized one.

Now I have come to the second bathroom and found that the galvanized
nipple is seriously corroded. Perhaps the PVC nipple in the first
bathroom was there for a reason?

What is the correct material to use here?

Either use a brass nipple or change it to copper.
Pvc is fine too if you like the pvc. Its installed everywhere now but
Im still not thrilled with having an entire house plumbed with it.

White PVC, yes. It was the use of *gray* PVC that I was questioning.

I believe that typically grey PVC is Schedule 80 so it might be OK. Not
sure if PVC is colored grey for other reasons or not.
