When you have two different types of metal, they tend to corrode each other. I think it has to do with ions or something like that. Try looking that up on the Internet. I'd be glad to be proven wrong, so let me know what you find. --Thomas (found your site through Debbie's "I love Luisa" posting on blatherings) I think the Home Depot man was concerned that you were using two different types of metal, not that one of them is galvanized.

(If he did know about it, the Home Depot man could have explained that to me!) Here's something I did find on the Internet (a little difficult to understand): <a>http://www.freepapers.net/essays/Corrosion_and_Rusting.science.shtml</a> I've also seen some sites mention a problem when joining metal parts with screws of a different type of metal. I think, too, that some other corrosive element might have to be present: water, or something? As in this quote about corrosion: "Dissimilar metals in the presence of a conducting liquid, known as the electrolyte, develop an electrical potential that causes a current to flow whenever a suitable path is provided." The above was from this site: http://irc.nrc-cnrc.gc.ca/cbd/cbd020e.html Well, that's enough digging for today!! I'll keep an eye on the two different pipes, but I don't think I have much to worry about. Interesting.. don’t know much about that.
