About Lee's Summit's Water

Hard Water in Lee's Summit: Impact on Plumbing and Appliances

At 9.6 grains per gallon, Lee's Summit's water qualifies as 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.
