oops bill, emt and steel studs, duh, sometimes i type faster than i think [dont make fun, that was my first fopaw, sp?][this would be a good place for a smilie, if i knew how to make a smiley face with crossed eyes and my tongue sticking out the side, kind of like brittany spears commercials], but yeah i suppose what he was talking about was the alum mc and steel. and the corrosive conditions arent an issue in this case, rattling could be though..... anyway what i was wondering about here was how far everybody goes with this. i have put insulation between copper water lines and mc and emt, but have wondered if it should be put between mc/emt and galv sprinkler lines or black iron gas pipe, and if you all even bother to separate the copper waters and mc/emt? and seriously, does anyone separate alum mc from the steel studs because of galvanic action, if thats what its called? [we use mostly mc tuff, and i think that its steel, but also use aluminum mc]
