Minnesota water is hard on your home.
Scale in your water heater. Spots on your glass. Dry skin after every shower. See what the public records say about your water, then let us test what's actually coming out of your tap.
Looks clean. Is it?Your water can look clean and still cause problems.
Hardness minerals, chlorine, iron, lead and PFAS don't always change how water looks. Most homeowners never test their water until something goes wrong: a failed water heater, a stained tub, or a boil advisory on the news.
- Public reports show the treated supply, not your tap
- Older homes can have lead service lines or plumbing
- Private wells aren't regulated. Testing is up to you.
Hard water vs. soft waterIf it's on your faucet, it's inside your water heater.
The white crust on your fixtures builds up the same way inside your water heater, dishwasher, washing machine and pipes. It makes them work harder and wear out sooner.

What's bugging you about your water?
Tap what you're dealing with. We'll show you what usually fixes it. Your free test confirms it.
Water Softener
Hardness is the #1 water problem in Minnesota homes. A properly sized softener removes the calcium and magnesium that build scale.
- Demand-based smart regeneration
- Sized to your grains per gallon
- Protects water heater & appliances
Professionally installedHard water in. Soft water to every tap.
Inside the tank, resin beads trade the calcium and magnesium that cause scale for sodium or potassium. The minerals rinse away, and soft water flows through the whole house.
- Removes the minerals that cause scale
- Protects pipes, water heaters and appliances
- Less soap and detergent. Spot-free dishes.
- Smart valve regenerates only when needed, saving salt and water

Water softener FAQs.
Do I need a water softener in the Twin Cities?
Many Twin Cities homes have hard water, especially suburbs and rural homes on groundwater or private wells. If you see white scale on faucets and shower glass, spotty dishes, stiff laundry or a water heater that's losing efficiency, a free water test will tell you your hardness and whether a softener makes sense.
Is Minneapolis or St. Paul water hard?
Both cities treat and partially soften their water, so it's moderately hard. Many suburban cities and private wells have harder water. Your test results show your exact hardness in grains per gallon.
What's the difference between a water softener and a water filter?
A softener removes hardness minerals (calcium and magnesium) that cause scale. A filter reduces things like chlorine, taste and odor, sediment, and, with the right media, some contaminants. Many homes benefit from both, which is why we test first.
How does the free water report work?
Enter your address and we look up your public water system, its most recent reported hardness and any violations on record, plus recent local news about water in your area. It's a starting point. Your in-home test shows what's actually coming out of your tap.
Is the water test really free?
Yes. We test your water in your home at no cost and walk you through the results. You're never obligated to buy anything.
Can a system remove lead or PFAS?
Some filtration systems are certified to reduce specific contaminants like lead or certain PFAS. We'll only recommend equipment certified for what your results show, and we'll tell you if a lab test is a better next step.
What warranty do you offer?
Equipment is covered by the manufacturer's warranty, and Repair King backs its installation with a 2-year workmanship warranty.
Public water data reflects the treated supply, not your home's tap. In-home tests are screening tests; for health-related contaminants such as lead or PFAS we may recommend a certified laboratory test. Equipment performance varies by model and water conditions.
