About Covington's Water

Covington Hard Water: Effects on Your Home

Hard water conditions in Covington (8.2 GPG) can leave white mineral deposits on fixtures, reduce soap lather, and gradually damage water-using appliances. Water heaters are particularly vulnerable: scale insulates the heating element, raising energy costs and reducing lifespan. A water softener exchanging calcium and magnesium for sodium eliminates scale formation throughout the home. For households concerned about sodium in drinking water, pairing a softener with an RO system at the kitchen tap is the standard approach.
