Service cycle
Hard water flows through the mineral tank. Resin captures calcium and magnesium, and treated water continues into the home.

How a Water Softener Works
A cation-exchange softener passes hard water through resin that holds sodium or potassium ions. Calcium and magnesium exchange onto the resin. When capacity is used, the control valve regenerates the resin with brine, then rinses it for another service cycle.
Regeneration cycle
The valve backwashes the bed, draws brine through the resin and rinses away displaced hardness minerals. A demand-initiated control starts this based on measured use or remaining capacity.
What softening does not do
It does not automatically remove every contaminant, disinfect water or replace a drinking-water filter. Each additional concern needs its own evidence and treatment method.
Questions homeowners ask
Frequently asked questions
Why does the system need a drain?
Regeneration sends rinse water and displaced minerals to an approved drain.
Why add salt?
Salt makes the brine that recharges the resin’s exchange sites.
What controls efficiency?
Resin capacity, programming, hardness, household use, salt dose and regeneration design.
