FAQ - What is water hardness?
Article Number: 46 | Rating: 3/5 from 1 votes | Last Updated: Mon, Oct 6, 2014 5:05 PM
Water hardness is the measure of dissolved calcium, magnesium, and other minerals in your drinking water. It is typically measured in grains of hardness which equates to 17.1 mg/L of dissolved calcium carbonate. If not treated hard water can cause mineral build-up in your heater. Mineral build-up reduces flow and produces flakes at your fixtures.
