I've never seen a home that uses the softened water for drinking. Mine has a raw-water tap in the kitchen for drinking water ; the rest of the home is softened water, except the outdoor tap. We use a Brita filter for the raw water - just to get a bit of the iron. The water softener works fine to get the low-level iron from the wash water - we use the "rust remover" softener salt in the softener. adding even more scary chemicals ! :-) John T.
