Water Treatment Systems for St. Louis Homes and Facilities

Your water might look clean, but the minerals and contaminants common in St. Louis can still take a toll on your home and your family. Hard water destroys appliances. Chlorine dries out skin and hair. PFAS and lead don’t have a taste or smell. We install water treatment systems across the St. Louis region that remove everything you don’t want in your drinking water.

Water Treatment Systems

Professional installation of water softeners, dechlorination systems, and reverse osmosis systems for homes and facilities across the St. Louis region.

01

Water Softener Systems

Hard water leaves mineral buildup in your pipes, shortens appliance lifespan, and creates stubborn staining on fixtures and dishes. Water softeners remove the calcium and magnesium that cause these problems before they reach your home.

  • Eliminates scale buildup in pipes and on fixtures
  • Extends the life of water heaters, dishwashers, and washing machines
  • Can be integrated with dechlorination for complete treatment

02

Reverse Osmosis Systems

Your tap water contains contaminants you can’t see, taste, or smell – PFAS, lead, chlorine, and other substances that standard filters don’t remove. Reverse osmosis systems filter water at the molecular level, removing up to 99% of contaminants.

  • Under-sink RO system installation by trained technicians
  • Removes PFAS, lead, chlorine, and other contaminants
  • Clean drinking water at every tap it’s connected to
  • Professional installation for homes and facilities

03

Dechlorination Systems

Municipal water treatment adds chlorine to kill bacteria, but that chlorine stays in your water and affects everything it touches. Dechlorination systems remove chlorine from your entire water supply before it reaches your taps.

  • Whole-home or whole-facility dechlorination using Kinetico systems
  • Activated carbon filtration that removes chlorine throughout your building
  • Can be installed standalone or integrated with water softeners
  • Protects plumbing, fixtures, and equipment from chlorine damage

What Makes St. Louis Water Hard on Homes and Families

Most water issues in the St. Louis area stay invisible until they’ve already caused damage or affected your family. Hard water looks clear. PFAS has no taste. Chlorine barely shows itself. These are the problems that untreated water creates in local homes:

Hard Water (Limestone Deposits)

Mineral buildup inside pipes, shorter water-heater lifespan, film on dishes and fixtures, and skin and hair that stay dry no matter how much you rinse.

PFAS Contamination

Industrial “forever chemicals” found in many Midwest supplies. Municipal systems don’t remove them, and they require reverse osmosis to filter out.

Chlorine & Chemical Additives

Dry skin and hair after showers, a chemical taste in drinking water, and long-term wear on fixtures with a noticeable smell in hot water.

Lead from Aging Pipes

Common in older St. Louis homes. Even low amounts affect children’s development, and standard filters don’t catch it – reverse osmosis does.

What’s Your Water Score?

Before you treat your water, you need to know what’s actually in it. We provide free professional water testing that shows you exactly what contaminants and minerals are present – so you can make informed decisions about treatment.

Why We Install Kinetico Systems

Not all water treatment systems work the same. We install Kinetico because their technology solves problems other brands can’t – and they do it without needing electricity or creating the maintenance headaches that come with cheaper systems.

E

Kinetico softeners run on water pressure, not electricity.

No timers that break, no electronics that fail. The system regenerates based on actual water usage, not arbitrary schedules, which means it works more efficiently and uses less salt.
E

Kinetico RO systems remove up to 99% of contaminants.

This includes PFAS, lead, chlorine, and hundreds of other substances that standard filters miss. You get clean water at the molecular level.
E

Built to last with fewer moving parts.

Kinetico systems are engineered for longevity. Fewer components mean less maintenance and fewer service calls over the system’s lifetime.
E

Professional installation and ongoing support.

We handle the entire installation, ensure the system is sized correctly for your home or facility, and provide service when you need it.
