I'm going to replace my galvanized tank with a new fiberglass tank.
1) Is there any reason to put a union on the lines going in and out of the tank somewhere?
The current tank doesn't have them, nor has it moved in 30 some years. I can't think of why I'd have to remove it other than replacing it again at some time. If I should use them, is there any reason to use dielectric unions? All of the galvanized piping will be removed and the tank itself isn't conductive.
2) I'm wondering what the fitting is on the copper coming through the wall. It seems like a female adapter but the hex nipple threaded into it seems to have 2 different threads on it. At least the threads look slightly different. One end (further from the wall) looks to have a male NPT thread. The end threaded into the adapter doesn't look the same. Almost like it may be a straight thread. Are my eyes playing tricks on me? Is it really just a female adapter?
Thanks.
Thanks.
