Water Softening in Minnesota

Water softening in Minnesota is not something that can be ignored by homeowners. With our high iron content in Minnesota we have specific, high demand water softening needs. Water Doctors designs custom-engineered water softening systems to meet the specific needs for your area of Minnesota.

 How to Know If You Have Hard Water

Some of the most telling signs of your need for water softening show up with soap in your laundry and showers and with stains on your fixtures and dishes. Aside from a distinct metallic smell or taste, you may notice some of the following: 

  • dishes stained with spots and soap scum
  • water fixtures with build up of minerals (issues like orange stains in your toilet)
  • soap that won’t lather well or rinse off completely
  • dingy, scratchy laundry
  • build up of scale deposits in your plumbing
  • skin conditions like eczema and hair that is dry and frizzy

How a Water Softening System Works

Water softening works by ion exchange. Ion exchange refers to the process where calcium and magnesium ions are removed from the water. All the water flowing into your house passes through a media tank full of beads. These beads collect the calcium and magnesium ions before they enter your home's various water supplies. Later, when your water softening system isn't being used (like in the middle of the night), the water softener cleans the tank, and those media that were used to remove the calcium and magnesium ions are ready for another cleaning cycle of hard water. 

Components of a water softening system

Backwashing: Cleaning the silica media (the beads in the media tank) of any sediment or build up.

Brine Cycle: Brine, which is made when the water softening salt in the brine tank is touching the water that is pumped into the media tank. This washes those media of all the calcium and magnesium ions in the water. It flushes those calcium and magnesium ions down your home's drain.

Rinse: Water is then pumped through the media tank again to remove all the brine from the media before the tank fills again with more hard water that will be treated with the softening process.

Water Doctors Custom-Engineered Water Softening Systems

Since Minnesota water is some of the hardest water in the country, water softening systems have a significant demand placed on them. Minnesota's rich resources of iron ore are one practical explanation for the significantly high water hardness numbers. But throughout the state, water hardness levels vary and present significant challenges to home owners. A custom-engineered water softening system from Water Doctors provides water softening that's specifically engineered for your water, whether in the suburbs or on the iron range. 

Water Doctors is the leading water treatment and water softening expert in Minnesota, providing industry leadership for more than 30 years. If you would like a free water analysis to check the hardness of your water, let us know. We can help you find the best water softening solution for your needs.

Custom-Engineered Water Softeners for MN

Minnesota is known for its hard water, and each area of Minnesota has specific water softening needs. With stains forming on dishes and bathtubs, laundry becoming worn, and skin getting itchy, hard water can be a nuisance. With appliances like water heaters running inefficiently and household plumbing building up with scales, hard water can be expensive. 

That is why Water Doctors offers custom-engineered water softeners to meet the demands of the high iron content of Minnesota’s groundwater. 

How Water Softeners Work

A water softener works by a process of ion exchange. Ion exchange refers to the process where calcium and magnesium ions are removed from the water. All the water flowing into your house passes through a media tank full of beads. These beads collect the calcium and magnesium ions before they enter your home's various water supplies.

Backwashing: Cleaning the silica media (the beads) of any sediment or build up. 

Brine Cycle: Brine is made when the water softening salt in the brine tank is touching the water that's pumped into the media tank. This washes those media of all the calcium and magnesium ions that they are designed to extract from the water and flushes them down your home's drain. 

Rinse: Water is then pumped through the media tank again to remove all the brine from the media before the tank fills with more hard water to be treated by the water softener.

Unique demands of MN Water Softeners

Why are custom-engineered water softeners necessary? 

Water Softeners in Minnesota have a significant demand placed on them. Minnesota, after all, is known as one of a few places in the country with noticeably hard water. Minnesota's rich resources of iron ore are one practical explanation for the significantly high water hardness numbers. But throughout the state, water hardness levels vary and present significant challenges to home owners. As a solution, a water softener should be customized for the size of your home and hardness of your water.

It’s Water Softener Time in New Brighton

As you probably know, New Brighton residents have switched back to local water resources from Minneapolis water. And if you know anything about New Brighton water, you know that this means it's time to turn on your water softener again.

Now that the work on Water Treatment Plant 1 (WTP1) is wrapping up, it means the change back to New Brighton water has already happened for just about all New Brighton residents. This means that it’s time to start thinking about your water softener again. 


If you have a water softener but haven't used it in a while, you'll want to make sure it's serviced. Servicing your water softener maintains efficiency. It also ensures that you are preserving the life not only of your equipment, but of your plumbing and other appliances (such as your washer and dishwasher) as well.

 Have Your Water Softener Serviced

 

The change to Minneapolis city water originally happened because trace amounts of 1,4-dioxane (dioxane) were found in New Brighton's water. Similar toxins at various levels exist in water throughout the metro area. If you want to know exactly what's in your water, you should have your water tested.

RUST SHIELD II Irrigation System Rust Management & Stain Inhibitor

Rust-Shield II™ DRY Chemical Sequestering system encapsulates the iron molecule so oxygen cannot convert it to ugly rust stains, therefore shielding and preventing stains before they cover your curbs, walks, siding, plants and driveway. WATER DOCTORS Rust-Shield II™  system is very simple and inexpensive to operate compared to the liquid chemical feed systems. The granular concentration of our chemical lasts 3 times longer than other preventers at 1/2 the cost. With easy installation and injection in the irrigation feed line in the basement, the system is designed to work with all lawn sprinkler systems.

  WATER DOCTORS Rust-Shield II™ products are a family of "chelating" chemicals. Each is specific to certain well water conditions and applications. These chelating chemicals have in common that if they can attach themselves to the ferrous iron in the well water before it meets oxygen at the sprinkler head, the iron will sequester or bind up so that it will not combine with oxygen. In effect, we “Shield” the iron from contact with oxygen. Water Doctors offers a 1-year performance guarantee if the well has been chlorinated and is free of iron bacteria or sulfate reducing
