What Does Water Softener Installation Include?
A water softener removes minerals like calcium and magnesium that cause hard water. Hard water leads to scale buildup in pipes and appliances, soap scum, dry skin, and reduced appliance lifespan. Softeners use ion exchange to replace hard minerals with sodium.
The national average cost for water softener installation is $1,800 installed. Most homeowners pay between $800 and $3,500, though costs can vary significantly based on your location, the scope of work, and other factors outlined below.

Frequently Asked Questions
How do I know if I need a water softener?
Test your water hardness. Above 7 grains per gallon (GPG) is considered hard and benefits from softening. Signs include white scale on fixtures, soap that doesn't lather well, and dry skin/hair.
Do water softeners add sodium to drinking water?
Yes, but a very small amount — about 12-25 mg per 8 oz glass for moderately hard water. This is less than a slice of bread. For sodium-free options, consider a reverse osmosis filter at the kitchen tap.
