I took it apart since the sheet metal was rusting and noticed some small corrosion where the fittings screw into the tank. How do you feel about aluminum for water? I don't drink the hot water and the storage tank is stainless steel, and the pipes are all copper.

I read that aluminum plaques form in the brains of people and cause Alzheimer, I generally think of aluminum as bad if you eat it, so why are water tanks made of aluminum?
(soda cans are supposedly coated)
