Straight Answers About Your Water Quality

Most homeowners have the same questions about their water quality before they schedule a free water test with Midwest Water Company in Moline, IL.

Quad Cities Water Quality, Explained


  • What is actually in Moline tap water?

    Moline's municipal water comes from the Mississippi River and meets federal Safe Drinking Water Act standards. That said, it commonly contains elevated hardness minerals, chlorine added during treatment, trace sediment, and in older homes, residual lead from pipes. Meeting the legal limit and being ideal for drinking or appliance health are two different things.

  • How do I know if I have hard water in my home?

    The most common signs of hard water are white, chalky buildup around faucets and showerheads, soap that doesn't lather well, stiff or dingy laundry, and spots on dishes and glassware. Skin that feels dry after showering is another indicator. A free in-home water test from Midwest Water Company will give you an exact hardness reading.

  • Is the Quad Cities water safe to drink straight from the tap?

    Quad Cities tap water meets federal drinking water standards, so it is legally considered safe. However, standards are set at a population level — they don't account for your specific pipes, your household's sensitivity, or contaminants that fall below the action threshold but still affect taste, odor, and long-term appliance wear.

  • What does water hardness actually do to a home?

    Hard water leaves mineral scale inside pipes, water heaters, dishwashers, and washing machines — reducing efficiency and shortening appliance life. It leaves visible deposits on fixtures and glass. It interferes with soap and detergent performance. Over time, the cumulative cost in repairs, replacements, and wasted product adds up significantly for most households.

  • Does the water report my city publishes tell me everything I need to know?

    City water quality reports cover regulated contaminants at the treatment plant. They don't reflect what happens inside your home's plumbing, especially in older homes with lead solder or galvanized pipes. They also don't test for hardness levels or emerging contaminants not yet covered by federal regulations. An in-home test gives you data specific to your tap.

Water Softener Questions, Answered


  • How does a water softener actually work?

    A water softener removes calcium and magnesium — the minerals that cause hardness — through a process called ion exchange. Hard water passes through a resin bed that swaps hardness minerals for sodium ions, producing softened water. The resin regenerates periodically using a salt solution, which flushes the captured minerals out of the system and down the drain.

  • How long does a Kinetico water softener last?

    Kinetico water softeners are built to last 20 years or more with proper maintenance. Because they're powered by water pressure rather than electricity, there are fewer components that can fail. The non-electric design means no circuit boards or timers to replace. Most homeowners in the Quad Cities who install a Kinetico system treat it as a one-time purchase.

  • Does a water softener require salt, and how often does it need to be refilled?

    Yes — traditional ion exchange softeners use salt to regenerate the resin bed. How often you refill depends on your water hardness and household water use. A typical Quad Cities home refills the brine tank every 4 to 8 weeks. Kinetico's demand-driven regeneration only runs the cycle when needed, so it uses less salt than timer-based systems.

  • What is the difference between a Kinetico water softener and a unit from a hardware store?

    Kinetico softeners are non-electric, demand-operated, and use a twin-tank design that ensures softened water is always available — even during regeneration. Box-store units run on timers, regenerate whether they need to or not, and have a shorter service life. Kinetico systems are backed by a professional installation and a warranty supported by a local dealer, not a 1-800 number.

  • Will a water softener affect the taste of my drinking water?

    Softened water has a slightly different mineral profile than hard water — some people notice it, most don't. The sodium added during ion exchange is minimal, but it is present. If drinking water taste matters to you, pairing a softener with a Kinetico drinking water system at the kitchen tap gives you both soft water throughout the home and great-tasting water at the point of use.

Filtration and Drinking Water Systems


  • What is the difference between a water softener and a water filtration system?

    A water softener targets hardness minerals — calcium and magnesium — and removes them through ion exchange. A water filtration system removes a broader range of contaminants: sediment, chlorine, chloramines, organic compounds, and other impurities. The two systems do different jobs. Many homeowners in the Quad Cities benefit from running both, depending on what their water test shows.

  • What does a whole-home water filtration system actually remove from the water?

    A whole-home filtration system installed at the point of entry treats all the water entering your home before it reaches any faucet, appliance, or shower. Depending on the system, it removes sediment, chlorine, chloramines, volatile organic compounds, and certain heavy metals. Kinetico whole-home filters are sized and configured based on what your specific water test results show.

  • Do I need both a water softener and a filtration system, or will one do the job?

    It depends on your water. Softeners address hardness. Filtration addresses a different category of contaminants. If your water test shows both high hardness and elevated chlorine or sediment, running both systems together gives you complete protection. Midwest Water Company reviews your water test results and recommends only what your water actually needs — not a package that sells more equipment than necessary.

  • What is a drinking water system, and how is it different from a whole-home filter?

    A drinking water system — also called a point-of-use filter — treats water at a single tap, typically under the kitchen sink. It provides a final stage of filtration specifically for water you consume. A whole-home filter treats all incoming water. Both serve different purposes: one protects your whole house, the other optimizes the water you drink and cook with directly.

  • How often does a Kinetico filtration system need to be serviced or have filters replaced?

    Kinetico filtration systems are designed for low maintenance. Filter replacement frequency depends on your water quality and household water use, but most systems need attention once or twice a year. Midwest Water Company handles service visits and filter replacements for customers throughout the Quad Cities, so you're not managing it alone after the initial installation is done.

What to Expect From the Free Water Test


  • What does the free water test from Midwest Water Company check for?

    The free in-home water test checks for water hardness, total dissolved solids, pH, chlorine levels, iron content, and other common contaminants found in Quad Cities tap water. The test is performed at your kitchen tap using professional-grade equipment. You get real numbers, not a vague assessment, and Midwest Water Company walks you through what every result means.

  • How long does the free in-home water test take?

    Most in-home water tests take 30 to 45 minutes from start to finish. That includes running the test at your tap, reviewing the results with you on the spot, and answering your questions about what the numbers mean and what — if anything — your water needs. There's no sales pressure. If your water is fine, we'll tell you that too.

  • Is the free water test really free, or is there a catch?

    It's genuinely free. No purchase required, no commitment, no follow-up sales calls you didn't ask for. Midwest Water Company offers the free water test because it's the right starting point — you can't recommend a solution without knowing what's actually in the water. Some homeowners find their water needs no treatment at all, and that's a completely fine outcome.

  • What happens after the water test results are shared with me?

    After reviewing your results, Midwest Water Company will explain what the numbers mean in plain terms and, if treatment is warranted, describe which Kinetico system fits your specific situation. You decide whether to move forward — there's no pressure to commit on the spot. If you want time to think, take it. We're a local business; we're not going anywhere.
