Water Softener Installation: What to Expect

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

What does a home water conditioner do?
Any kind of system that improves the quality of your water through some type of water treatment – be it softening, filtration or both – can be considered a home water conditioner. Having a whole house water conditioner like the HE Municipal Water Conditioner can help combat the effects of hard water, including dry skin and hair, limescale buildup around faucets and showerheads, soap scum on shower walls or inefficiency or breakdown of your water-using appliances. This particular conditioner is a dual softener and filtration system, so it also addresses the negative impacts of too much chlorine in your water, improving its taste and smell.
Because water softeners are typically installed where your water source enters your home, getting a water softener may be possible for an apartment or condo depending on access to plumbing but generally would be a decision made with your landlord or association.
The municipal system targets chlorine, which is common in city water supplies, but it may also be an issue in some well water homes if chlorine is used to treat your well water. We recommend scheduling a free, in-home consultation today and a Culligan water expert will help you determine what your home needs.
Your local Culligan water expert can help determine what 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.
Both city water and well water can have varying levels of hardness and mineral content depending on where the water is sourced from. Your local Culligan water expert can help find the best solutions for your water’s hardness and any other specific needs.
Do I need a water softener for my home if I have city water?
Yes, if you have hard water. Water hardness varies depending on your geographic location, the source of your water and more. Even if your water comes from a city treatment plant, it can still be hard. For this reason, you may need a water conditioner for your home use if you have municipal water.
Yes. The Dial-a-Softness® control allows you to customize the feel of your water to the softness level you prefer. There are also additional product options to further customize your experience, including proportional brining, the Salt Level Monitor and the Leak Sensor.
Yes. The Culligan water softener and filter system uses activated carbon filtration to address chlorine tastes and odors in your water.
Yes. For the best all-around water experience for your home, it may be recommended to combine multiple systems. While this municipal water system softens water and filters chlorine, other options like a whole house filtration system can help address any additional problems your water may have, such as iron, sediment or hydrogen sulfide. For a drinking water solution that provides comprehensive filtration for more than 70 contaminants, check out Culligan’s reverse osmosis water filtration systems.³

Our city water has become much softer & thankfully no more chlorine ... no more dry skin.

The technicians were very professional and installed the system where we wanted it to be placed. Excellent product.

— Arun and Kumar P, MD

I upgraded to a soft water system … one of the smartest decisions I’ve made.

I use less laundry/dish soap and don’t need lotion to soften my skin.

Brett did a great job installing the HE Municipal water softener …

and explaining the product after installation.
