Water treatment and water purification systems from Grainger are excellent for providing clean, safe water for drinking, cooking, washing and bathing. High mineral content in public and groundwater systems cause hard water, which leads to damaged appliances, clogged fixtures and a noticeable taste or odor. Install a water softener to reduce or even eliminate hard water problems. A water filtration system efficiently clears sediment, while a water test kit can analyze bacteria, lead, pesticide and nitrate levels in your water. Count on Grainger for your water treatment and water purification system needs.
