I've heard that all galvanized pipe to copper connections need a dielectric (sp?) union to prevent premature corrosion.

My first question is...is this true? The reason I ask is I just looked at a home I may purchase and I noticed that there were a few connections where some new copper pipe (with threaded coupling) was threaded directly into the existing galvanized water supply line. Is this going to be an issue?

Thanks for your help!!!

Most areas are adamant about using dielectric unions between dissimilar metals.

I don't use them because I get more calls on the rubber gaskets than I do from electrolysis. I install teflon tape on a copper male adapter into a female galvanized fitting and have not had the electrolysis in the last 15 years. I'm a minority view compared to other areas.

But it doesn't matter because the galvanized has a limited life and is going to have to be replaced at sometime anyway. The sellers evidently didn't have the money for a complete repipe so they have only replaced the worse places as they begin leaking.

Thanks for the info...at least I know I have some time. If the house works out, then next spring I can go through and replace all of the old pipe. Fortunately it's a small house so it shouldn't take much.

Thanks again!!
