Water Softeners questions, answered by experts

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

A water softener is a worthwhile investment if you live in an area with hard water. While hard water is safe to drink, it contains minerals like calcium and magnesium that can cause significant problems over time. These minerals build up inside pipes, reducing water flow and eventually corroding the plumbing system, which can lead to leaks and a shortened lifespan. Hard water also damages fixtures and appliances, potentially resulting in costly repairs. Additionally, it makes soaps and detergents less effective, meaning you'll use more product to get things clean. By installing a water softener, you can prevent these issues. The initial investment is often recouped through long-term savings, including lower energy bills, reduced appliance and plumbing maintenance, and spending less on soap and cleaning supplies. Other benefits include cleaner linens, dishes, and clothing, as well as softer water that is gentler on your skin and hair. In some areas, a water softener can also increase your home's value, making it a valuable long-term investment.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.
