Everything You Need to Know About Water Quality, Filtration, and Maintenance

At Real Water Systems, we believe that clean water starts with clear answers. Below, we’ve compiled the most common questions we get from homeowners, business owners, and property managers across Diamond, MO, and the surrounding areas.


Whether you're curious about how filtration systems work, what makes well water different, or how to maintain your softener, we’ve got you covered.

Water Quality Faqs

  • How do I know if my water is “bad”?

    Signs of poor water quality include:

    Stains on sinks or toilets (orange, red, or white)


    • Rotten egg or metallic odors
    • Dry skin and hair
    • Cloudy or off-tasting water
    • White buildup on faucets or glassware

    The only way to know for sure is with a professional water test. We offer in-person testing at no cost, so you can make an informed decision.


  • Do I need to test my well water every year?

    Yes. Annual testing is highly recommended for all private wells, especially for bacteria, iron, pH, and sulfur. You should also test after floods, heavy rain, plumbing changes, or if you notice taste or odor changes.


  • What’s the difference between city water and well water?

    City water is pre-treated with chemicals (usually chlorine) and follows EPA guidelines — but it may still contain hardness, residual chemicals, or taste issues.

     Well water is untreated and varies widely in quality — often containing iron, sulfur, sediment, and bacteria. Both sources can benefit from tailored filtration.

Filtration & Softening Faqs

  • What’s the difference between a softener and a filter?

    A water softener removes hardness minerals like calcium and magnesium to reduce scale.


    • A water filter removes contaminants like chlorine, iron, sulfur, sediment, or bacteria.
    • Some homes need one system; others may benefit from a combination.
  • What is a salt-less water system?

    Salt-less systems don’t soften water in the traditional sense. Instead, they condition water using physical processes that prevent scale buildup — without removing minerals. They’re great for low-maintenance scale control, but not always ideal for homes with very hard water.


  • Is reverse osmosis (RO) necessary?

    RO systems are ideal for drinking water at the kitchen sink or refrigerator. They remove:

    Heavy metals


    • Fluoride
    • Chlorine
    • Sodium
    • VOCs and other contaminants

    We often recommend RO alongside a whole-home filter or softener, especially for families with health concerns.

  • Can I use the same system for well water and city water?

    Not always. Well water often requires additional treatment for iron, sulfur, or bacteria. City water, on the other hand, may only need a softener and chlorine filter. That’s why we always test first and build a system based on your water source and needs.

Installation & Maintenance Faqs

  • Do you install the systems you sell?

    Yes — all installations are completed by our trained, local technicians. We do not subcontract. We handle plumbing, programming, and testing to ensure your system runs perfectly from day one.


  • What maintenance does a softener need?

    Salt-based softeners require:


    • Salt refills every 1–2 months, depending on usage
    • Annual system checks
    • Occasional cleaning or resin servicing (every 3–5 years)

    We offer maintenance plans, salt delivery, and annual system inspections to make it easy.

  • How often should I change my filters?

    It depends on your system and usage:


    • Sediment filters: every 6–12 months
    • Carbon filters: every 6–12 months
    • RO membranes: every 2–4 years
    • Pre/post filters in RO systems: every 6–12 months

    We can help you track replacements and provide all needed filters.


  • Will a softener damage my septic system?

    No. Modern softeners are septic-safe when installed and configured correctly. We use efficient units that minimize backwash volume and reduce sodium discharge.

General Questions

  • How much do your systems cost?

    Costs vary depending on the system type, water condition, and installation needs. We offer:


    • Free consultations and water testing
    • Transparent, up-front quotes
    • No high-pressure sales

    Many systems can be installed affordably — and they often pay for themselves by protecting appliances, saving on detergents, and improving efficiency.

  • Can I finance a water system?

    We offer two different finance options. Foundation Finance or Aqua Finance.

  • Do you offer service plans or filter delivery?

    Yes. We offer ongoing maintenance, filter replacements, and salt delivery plans. Whether you want to be hands-off or just need reminders, we’ll help keep your system running worry-free.
