I’ve been noting nat gas piping as needing repair whenever I see galvanized pipe mixed in with black iron. Never seen it in writing but was told that this causes a galvanic reaction and will eventually leak.
I recently had a plumber insist to me that its ok to mix the fittings and he claims many municiple building inspectors approve it. Does anyone know where I can find something in writing on the subject?
