How It Works

There are a few stages in the water conditioning process. First, during the service cycle, hard water enters the Media Tank and is forced through a Cullex resin column that replaces the hard minerals with soft minerals. The water is also filtered through carbon media to eliminate other contaminants and impurities like chlorine before it even enters your home.

Depending on the hardness of your water and soft water needs, the system will regenerate itself accordingly. During the regeneration cycle, the water is forced through the Cullex resin to flush out sediment. A brine solution is then drawn from the bottom of the salt storage tank and is also directed through the resin column, restoring the resin’s ability to remove hard minerals.

Finally, during the brine refill cycle, Culligan’s Dubl-Safe valve allows a predetermined amount of salt to be dissolved in the water to deliver the perfect amount of water softness for you family. The large tank of the Total Home Water System ensures your family will always have soft water.
