Common Problems Hague Can Solve

Hague systems are ideal for tackling the most widespread water issues in Southwest Missouri, including:

Hard Water (Calcium & Magnesium)

  • White buildup on fixtures and glass
  • Dry skin and hair
  • Reduced water heater efficiency
  • Shortened appliance life

Hague water softeners eliminate hardness minerals, extending appliance life and improving every drop of water you use.

Iron & Sulfur

  • Orange/rust staining in sinks and tubs
  • Rotten egg odor from hydrogen sulfide
  • Metallic taste

Many Hague systems include integrated iron filters and odor control to address these issues without needing separate units.

Chlorine & Chemical Byproducts

  • Strong chemical taste or smell from city water
  • Skin irritation and drying
  • Concerns about long-term exposure

Hague carbon filtration reduces chlorine and VOCs (volatile organic compounds) from treated municipal water.
