Hard water in your WI home

Hard water is water that has high mineral content. In Wisconsin, the main minerals that contribute to hard water are calcium and magnesium. While these minerals are not necessarily harmful to your health, they can cause a number of problems around your home.

What problems can Wisconsin’s hard water cause?

• Make it difficult to get your laundry clean
• Leave spots on dishes and glassware
• Excessive build-up or accumulation of materials inside plumbing fixtures and pipes can cause blockages, restricting the flow of water

These are clear signs that you may benefit from a water softener system

How to Treat Hard Water in Wisconsin

If you’re dealing with hard water in your home, there are several effective solutions you can try. Some we recommend are:

Use a water softener: This device removes minerals from your water supply, making it softer and more manageable.

Install a reverse osmosis system: This filtration system removes contaminants from your water source to yield healthier, better-tasting water.

Use water softener salt: This salt removes hard water minerals and helps extend the life of your appliances and plumbing fixtures.

Invest in a Culligan Water Cooler: The clean, refreshing water from a Culligan water cooler is ideal for drinking water–keeping everyone hydrated and energized throughout the day, without the price or waste of bottles.
