Signs Your Home Has Poor Water Quality

Everyone deserves access to a clean and safe water supply. Here are some of the most common signs that your home’s water quality could be compromised:

  • Bad smells: If your water has a rotten egg smell or other foul odor, your pipes could have bacterial growth. Water that smells like a swimming pool could have too much chlorine.
  • Metallic or bitter taste: Rusty pipes could leach excess iron or copper into your water supply.
  • Cloudy or discolored water: Mineral buildup or corroded pipes could contaminate drinking water. Cloudy water could indicate bacterial contamination or sediment.
  • Stained fixtures: Streaks of brown, yellow, or white indicate a hard water problem or buildup of calcium and lime. Streaks of red indicate excess iron in your water, while blue stains indicate copper contamination.
  • Health issues: Protecting your home’s water quality is crucial if you or a family member is experiencing a chronic health problem.

Comprehensive Water Treatment Services

While Kentuckiana’s water supply is treated and tested, your home’s water supply can be negatively impacted as it travels from city treatment centers to your pipes. A+ Derr installs whole-home water filtration systems and softeners to protect your home’s water supply.

Whole-Home Water Filtration

To filter and clean the water throughout your home, A+ Derr installs top-quality whole-home water filtration systems in Evansville, IN, and Louisville, KY. Installed at your home’s main water line, a whole-home water filtration system filters every drop of water that enters your home. Several types of water filtration systems improve the taste and smell of water, from basic sediment filters and granular activated carbon (GAC) filters to reverse osmosis systems that remove the widest range of contaminants.

Water Softeners

Thanks to abundant limestone underground, Kentuckiana’s water supply is hard, which means it contains high levels of naturally occurring minerals. Hard water isn’t harmful to your health, but over time, it leads to a buildup of limescale, damaging appliances, staining plumbing fixtures, and drying out skin and hair. These “hard” minerals also inhibit soap from lathering, making it harder to bathe or clean dishes and clothes.

To prevent hard water damage, A+ Derr installs leading water softening systems in Kentuckiana, including ion exchange softeners and salt-free systems. We can install whole-home water softeners or point-of-use systems for individual faucets, depending on your needs.

Choosing the Right Water Treatment System for Your Home

Your first step in choosing your home’s ideal water treatment system is testing your water supply. Once we clearly understand the issues with your water, A+ Derr can tailor your water treatment to your precise needs. For example, if hard water is an issue, you’ll need a softener.

If your hard water also has contaminants, you’ll need a full-filtration system that softens water and removes impurities. Once we determine the type of water treatment you need, we can pinpoint the optimal size to install based on the number of people in your home and the severity of your water concerns.
