What are the signs I have hard water damage in my home?

White or yellowish scale buildup around faucets, showerheads, and the inside of your toilet tank is the most visible sign. You may also notice dishes coming out of the dishwasher with spots or film, soap that doesn't lather well, dry or itchy skin after showering, and reduced water pressure from scale-clogged showerheads.

Long-term, hard water shortens the life of water heaters, washing machines, and dishwashers significantly — the American Water Works Association estimates hard water costs the average household hundreds of dollars per year in extra energy and appliance costs.
