water heater install


I have a few questions.
Replacing a 50 gal electric with a 50 gal electric, pipes come in over unit with plenty of room. I want to change the plumbing a bit and add some shutoffs (doesn't have any now) and stainless braided flex lines. With brass 1/4 turn shutoffs connecting to galvanized-will i need to do anything special? Right now there are galvanized unions connecting it. I want to take off the unions, put brass shutoffs in place, then run flex lines to the top of the tank. Should i use sealant tape or pipe dope for connection? T/P relief valve will run outside with existing pipe. Also are the new aluminum pans for setting the heater in, worth the 20 bucks or is it a waste? The present unit hasn't been leaking or anything but it's 22 y/o and i think one of the elements is out so rather than spend money on an old unit, i think i'll take the opportunity to just change it out. I just wondered about mainly hooking brass to galvanized-or do i worry too much?

Maybe I am missing something, but without unions how will you complete the connections?

Additionally I would bet those unions are "Diaelectric Unions" which prevent corrosion of dissimilar metals.

I do not like the SS braided flex lines, I think the corrugated copper flexes are better/stronger.

Thanks rj, i'll keep that in mind. I'll probably end up going with whichever is cheaper.
