Water Softener Installation: What to Expect

Learn everything you need to know about getting started with your smart water softener.

How is the Smart HE Municipal Water Softener different from a standard water softener?

Yes. Water softening systems are just one part of a complete water treatment approach. Your local Culligan water expert can recommend other solutions, such as a reverse osmosis drinking water filtration system, that will complement your softener based on your concerns and your water test results.

Do I need a water softener for my home if I have city water?

Your local Culligan water expert can help determine what size system you need by assessing factors like hardness of your water, pipe size, household water usage and flow rate. We recommend scheduling a free, in-home consultation to understand your water and get custom recommendations.

When it comes to city water vs. well water, the biggest factor in determining hardness is the likelihood of your water source encountering, absorbing and carrying calcium and magnesium — and how much. Although these minerals can be present in both water types, they’re especially common in well water.

The water softener is essential in our house.

I’m grateful for the Culligan product we have!
