What is a water softener?

A water softener is a device that reduces the hardness of water by removing minerals like calcium and magnesium.

How does a water softener work?

Water softeners work by replacing hard minerals in the water with softer ones, typically sodium, through a process called ion exchange.

How often should a water softener be replaced?

On average, water softeners last about 10-15 years, but this can vary depending on the quality of the unit and water hardness level.

Is a water softener necessary for all homes?

Not all homes need a water softener; it depends on the hardness of your water supply which can be determined through a water test.

What are the maintenance requirements for water softeners?

Maintenance typically involves regular addition of salt to the brine tank and occasional system checks and cleanings.
