Hardness In Drinking Water

“ Studies have shown that elevated levels of sodium in drinking water may have an adverse affect on health. Persons who suffer from high blood pressure or are on a sodium restricted diet should not drink water containing greater than 20 mg/l of sodium without first checking with a physician. A simple solution to the problem of consuming softened water is to have the kitchen cold water faucet bypass the water softener.”
