Hi all!
I'm trying to update some of the plumbing in my house (1922). Most of the galvanized pipe has been removed, but there's still a few pipes. Some are in very good shape (i.e. no rust at all, clean water coming out) and some have to go! Ideally, I'd like to replace all of them, but can't rip out walls right now.
Now to the question: if I update most of them with copper I know I have to use a dielectric fitting to join them, but do I have to use a dielectric union or can I use a dielectric nipple? I've heard about the unions leaking over time (we have some on our boiler pipes that do leak), but the dielectric nipples are just a solid piece.
Any thoughts? Suggestions?
Thanks,
Serge
