It is highly corrosive to metal  if its a bad idea for your homes plumbing, its a worse idea for your bodys plumbing! The EPA admits there are few studies on how chloramine affects human health. And if the EPA doesnt know, you dont either. Chloramines are more stable than chlorine  and therefore more difficult to remove.
