Residential water supplies are subject to a wide variety of purity and contamination issues, from mild to serious. Depending on water hardness testing results, homeowners may want to treat all water used throughout the home to reduce scale buildup in pipes, appliances, and water heaters. Visible signs of hard water include:
- Dry, itchy skin and dull hair
- Mineral buildup around faucets and drains
- Soap scum in showers and bath
- Filmy or cloudy residue on glassware
- Rough-feeling or faded clothing
