Galvanized with copper


Recommended Posts

Go here.

It's got the basic noble metal scale. Mixing metals that are farthest apart has a much greater chance for electrolysis. Sticking a brass nipple in there slows or eliminates the problem.

Some galvanized fittings have inner plastic sleeves to isolate dissimilar metals.

I wouldn't necessarily say the installation was wrong until I checked to see if the nipple was brass and the galvanized fitting lacked interior sleeves.

IOW, could be just fine.

Interesting - Thanks Kurt.
