Common Water Issues in Louisville

Solutions For Your Water Quality Problems

The primary source of Louisville's drinking water is the Ohio River. The water is collected and sent to a number of different treatment facilities before being distributed to local homes and businesses. While Louisville's municipal water exceeds all quality standards of the U.S. Environmental Protection Agency (EPA), water is still exposed to minerals and additives on its journey from source to treatment facility, and during treatment and filtration.

Hard, Poor-Quality Water

Due to its high mineral content, Louisville's water is considered hard. While perfectly safe to drink, the minerals in hard water can contribute to:

  • Dry, itchy skin
  • Stiff, scratchy, faded laundry
  • Buildup in pipes and plumbing
  • Soap scum around sinks, tubs, and fixtures

Limescale Buildup

Hard water can create a buildup of white scale or lime on your faucets and appliances. When using hard water throughout your home, limescale can appear in the form of:

  • Chalky buildup on fixtures
  • Buildup in pots, pans, and kettles
  • Clogged showerheads and faucets

Spotty, Cloudy Glassware

Even after running the dishwasher, hard water can cause spots, streaks, and cloudy residue to appear on freshly cleaned glassware.

Your local Louisville Culligan Water Expert is an expert on your water, can test it to determine any problems, and provide the best way to address them.

Tips From the Culligan Water Expert

To check for toilet leaks, put food coloring in your toilet tank. If it seeps into the bowl without flushing, there's a leak. Fix it to start saving gallons of water.
