Water Treatment Systems in Chicagoland

Do you ever stop to think about what’s in your drinking water? While Chicagoland’s water is generally safe, it’s natural to be concerned about the taste, odor, hardness, and potential contaminants such as lead, nitrates, and disinfection by-products. A water treatment system offers a reliable solution—ensuring safe, clean, and great-tasting water throughout your home or business.

As your local expert, Center Guard Plumbing specializes in installing and maintaining water filtration systems and reverse osmosis (RO) systems across the Chicagoland area. Whether you’re upgrading your entire home or just improving your drinking water, our services deliver tailored solutions for every need.

Understanding Your Water: Common Issues and Our Solutions

So what’s in your water? Here are some of the most frequent water quality challenges Chicagoland area homes face and the problems they can cause. 

  • Hard Water: High levels of dissolved minerals, like calcium and magnesium, cause hard water. This can leave spots on dishes and clothing, damage plumbing, and shorten appliance lifespans. 
  • Unpleasant Taste & Odor: Chlorine, sulfur, or dissolved organic compounds can affect the flavor and smell of your water. Although it’s still deemed safe to drink, it may not taste pleasant.
  • Contaminants: Trace amounts of lead, nitrates, or disinfection by-products (such as trihalomethanes) may still be present despite municipal treatment—especially in older systems.

Center Guard’s Solutions

While your water may be considered safe, it may still be unpleasant. However, Center Guard offers reliable solutions to improve your water quality and comfort. 

Whole-House Water Treatment Systems

A whole-house unit, as the name implies, treats all water entering your home, thus protecting plumbing, appliances, showers, laundry, and faucets. From bathing to cooking to laundry, you’ll quickly notice an improvement in your home’s water. 

Point-of-Use Systems (like RO)

A point-of-use system is installed at specific locations (such as your kitchen sink). These systems deliver highly purified water ideal for drinking and cooking.

Reverse Osmosis (RO) Systems: The Ultimate Filter

Why are Reverse Osmosis Systems so popular in Chicago homes? 

How It Works
Imagine water being pushed through a microscopic sieve—the RO membrane—blocking contaminants while allowing only pure water through. This process is highly effective because the membrane pores are so small that they stop even dissolved particles and chemicals that most standard filters cannot catch. The result is water that is exceptionally clean, safe, and refreshing.

Key Benefits of RO Systems

  • Removes Up to 99% of Contaminants: Reverse osmosis systems can eliminate lead, arsenic, fluoride, PFAS, nitrates, and disinfection by-products—substances that may be present in municipal supplies or well water.
  • Improves Clarity, Taste, and Odor: By stripping away chlorine, sulfur, and dissolved solids, RO water is noticeably clearer, fresher, and better tasting for drinking and cooking.
  • Supports Health and Sustainability: RO systems reduce reliance on bottled water, cutting household costs while helping to decrease plastic waste and protect the environment.

Water Softeners

Soft water makes a difference you can see and feel…
Soap & shampoo lathers better and won’t leave stains or buildup on your sinks and bathtubs. Dishes clean more easily and dry spot-free. Clothes come out of the laundry cleaner, softer & brighter. Water Heater & Appliances last longer with less maintenance.

Water softeners use salt to help remove the hardness from the water.  water with zero hardness will be described as soft for some, for others this is slimy.  Water is considered hard at 3.5 grains per gallon of hardness, Chicago water is 7 gpg and even harder the further you get from Chicago.  That being said almost everybody can benifit from a water softener.  Below are several reasons:
 
In the Bathroom: Soap and shampoo will lather better. Hair and skin will feel noticeably cleaner, softer and not as dry. No soap scum or mineral deposits to clean off sinks, showers, tubs or toilets.
 
In the Laundry:  Clothes will be softer, cleaner, whiter and brighter. Plus they will last longer. Using soft water increases the life of clothing, towels and linens up to 33%. Without hard water service issues, washing machines last longer, too.
 
In the Kitchen: Dishes will clean more easily, and be spot free, without the film glasses get when etched by mineral-laden water.
 
Throughout the House: Water-using appliances will last longer and run better. Why? Because hot water heaters, washing machines and dishwashers using hard water can wear out 30% faster.

Chemical Free!

Iron Filter - IronBreaker III

If your water has the sulfur odor of “rotten eggs”, if there are iron stains on your sinks and bathtubs, if you use large amounts of soap to clean dishes, wash your hair or suffer the “orange hair” effect sometimes caused by iron water, you probably have water that can be successfully treated with an IronBreaker III.

Well water and even city water can be full of iron. You more than likely are aware due to the staining in the toilet and shower. It is possible the well just needs to be chlorinated, this is something well owners should be doing once a year anyway. We will cover how to shock a well in the FAQ page. Iron in the water it can be seen or smelled (rotten eggs, sulfur) or both. The Iron Breaker will remove the iron and the smell. Best of all it uses air to regenerate. Maintenance free!

In the Bathroom:
No more iron stains or rotten egg odor. Soap and shampoo will lather better. Hair and skin will feel noticeably cleaner. And when used with a water softener, your iron free, odor free water will be soap scum free, without mineral deposits to clean off sinks, showers, tubs and toilets.

In the Laundry:
Without iron or H₂S in the water, clothes will be whiter and brighter. Plus, they will last longer. Add a water softener and increase the life of clothing, towels and linens by up to 33% and add even longer service life to your appliances.

In the Kitchen:
No iron stains on the sink, no objectionable odor while running water for cooking, cleaning or drinking. Dishes will clean more easily and, by adding a water softening unit, your dishes will be spot free without the film glasses get when etched by mineral-laden water.

Throughout the House:
Water using appliances will last longer and run better. Why? Because hot water heaters, washing machines and dishwashers using iron laden, hard water can wear out 30% faster, while consuming more energy than an appliance using iron free, H₂S free, soft water.

Reverse Osmosis

Whether you just want the fresh, clean taste of bottled water without the expense and waste, or you need protection from waterborne contaminates, a Point-of-Use System may be the best choice for you.

 Frequently asked questions about Reverse Osmosis:

Reverse osmosis water is water that has been passed through “a semipermeable membrane to remove ions, molecules, and larger particles” (Wikipedia)

It is currently the most effective water filtration method available. This technology is used to produce bottled water.

Most RO systems are designed to be installed under the kitchen sink. They can also be installed in the basement if need be.

If it is well serviced and parts are replaced in good time then virtually forever. The typical life span of the membrane is 2-5 years (depends on the initial water quality). The filters should be replaced every 6-12 months.

A water softener will actually extend the life of the membrane. By softening the water it helps to protect the RO unit.

In 1949, the University of California studied the effectiveness of semipermeable membranes (RO membranes) in the desalination (removal of salt) of seawater. Researchers then successfully produced fresh water from the salty seawater, in the middle of the 1950s. However, the process was still not a commercially viable one, and it took a while for the membrane technology to catch up. Scientists had proved it was a viable process, but the cost and technology involved in constructing a membrane with commercial appeal still held back progress. Scientist, John Cadotte eventually made the breakthrough, and by 2001, over 15,000 desalination plants could be found (or were being planned) around the world.

Today, reverse osmosis accounts for 80% of the desalination plants worldwide. The technology has also been converted for the home, and it remains one of the most effective methods of water filtration available to us. The discovery of the reverse osmosis method of filtration, and indeed the ability to do it cost-effectively, may be two of the most important scientific breakthroughs of recent times. With a rapidly increasing population, we are already starting to struggle to feed and water the world. Reverse osmosis has allowed us to source water from practically anywhere, and provided solutions to water shortages in countries throughout the world. Furthermore, water pollution is a bigger problem than ever, and continues to increase and gain massive media attention. Home reverse osmosis systems offer an affordable home solution to this problem. With contaminant rejection rates of up to 99% claimed by manufacturers like APEC, they can offer peace of mind  to families worried about the state of their drinking water.
