Question Galvanized Unions

I use 3/4" galvanized unions for plumbing gas lines to pool/spa heaters. Can these same unions be used in a galvanized water supply line? My main line developed a leak and this would be the easiest fix if they are usable. Thanks

Yes, if you really want to.

Personally, I'd rip out as much galvanized as possible and install copper.

The problem you'll probably run into is finding a section good enough to thread. If it is developing holes, that's not a good sign.

BTW: why not black iron on the gas work?

A galvanized union should work fine as long as it fits up right and you use pipe dope or teflon tape on all threaded joints.

If you decide to put in some copper, use dielectric unions at all copper/galvanized transitions or you'll cause corrosion problems.
