Water Softener Installation: What to Expect

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

Can this system effectively soften water and remove iron?​
Yes, the Aquasential Smart HE Softener-Cleer was designed to both soften water and address iron-related water issues, making it a great solution for those who have noticed rust stains around faucets or water-using appliances.
The Culligan Smart HE Softener-Cleer Plus is one of the best water softeners for well water with iron and hydrogen sulfide. Hydrogen sulfide can leave black stains on your laundry and bathroom fixtures, create rotten-egg odors and can cause damage to your pipes, leading to costly repairs.
Yes. Hard water is one of the most common problems for well owners. The Aquasential Smart HE Softener-Cleer can provide all the benefits of water softening for those who get their water from a private well as well as those with municipal water.
Hard water is often noticeable without testing and will appear as staining on bathroom and kitchen surfaces, spotty dishes and dry skin and hair. Similarly, iron will most often present as rust stains. That said, you can ensure your system is always working effectively over time by signing up for a service plan with your local Culligan service team. They’ll visit your home on a regular basis to ensure your softener is performing properly, offering you even greater peace of mind between inspections.
What size or capacity system do I need?​What size or capacity system do I need?​
Water softeners come in various sizes, and making sure that you have the best water softener for well water (or municipal water) is important. Getting the right size will allow you to make sure that you can soften your water sufficiently without losing efficiency and wasting extra water and salt by regenerating too often. The best way to accurately size your water softener is to work directly with a Culligan water expert to test your water, assess your flow rate and determine how much water your household uses on a regular basis. Generally speaking, harder water, higher water consumption and a greater number of taps running simultaneously mean that you’ll need a larger water softener. You don’t want to overshoot, though. Regular regeneration is also still required for optimal performance. Plus, larger units tend to cost more, meaning that purchasing an oversized softener might result in spending more money upfront than is necessary.
We design products that are built to last. Our systems have been tested against rigorous standards and have industry-leading warranties. The lifespan of your system can be impacted by usage, maintenance and water conditions, but you can expect your softener to last for many years. Periodic cleaning and maintenance will keep your water conditioner operating at peak efficiency.
Yes, you can easily save your treated water by putting your well water softener in bypass for any uses that don’t benefit from soft water. With the Culligan Connect App, you can easily put the unit in bypass mode from anywhere, for an all new level of control and convenience.
Iron in water can have several unfavorable effects in your home. It can cause a metallic taste in drinking water and lead to yellowing teeth. It can also clog wells and pumps and leave stains on dishes, laundry and water fixtures. If you suspect you have high levels of iron in your water, schedule a free, in-home water consultation with your local Culligan water expert today to find the best water softener for well water with iron.

We have already seen a difference in our water

after our softener system was installed, which previously was extremely hard and high in iron.

— Michael J, VA

They work!

We have very hard water with lots of iron. Their water softener works a lot better than any we had personally tried. Also, when we had a problem, it was fixed the same day.

— Gerald & Margaret H, WI

We like not having to worry about iron deposits on tub, washers, etc.

and the use of soap is less. Much better for our septic system as well. Soft water is a luxury and we enjoy it.
