Should I consider getting a water softener?

Personal Preference

Installation of a private water softener is a matter of personal preference. Because residential softening systems replace the calcium and magnesium with sodium, consumers will experience increased salt intake.  You are encouraged to research any water softener product, particularly customers with sodium-restricted diets. Water softened by private softening systems tends to be more corrosive to household plumbing than hard water, and it is not recommended for watering plants, lawns and gardens due to higher sodium content.
