About Minot's Water

Hard Water in Minot: Impact on Plumbing and Appliances

At 14.5 grains per gallon, Minot's water qualifies as very hard. Hard water carries dissolved calcium and magnesium that deposit as limescale inside pipes, water heaters, dishwashers, and washing machines over time. Scale accumulation reduces appliance efficiency and shortens service life. A salt-based water softener is the most effective solution for whole-home protection. For drinking water only, a reverse osmosis system also reduces mineral content significantly.
