How the WSM Water Softener Works:

Step 1:

Untreated water enters your home, and into the WSM's softening tank.


Step 2:

The water is softened as it passes through the softening resin.


Step 3:

Once softened, the water leaves the softening tank and is delivered throughout your home.



At precise intervals, the unit begins a regeneration process that restores and rejuvenates the softening resin. Using salt as a regenerant, the retained foreign substances are flushed out of the system and down the drain. The unit then prepares itself for the next conditioning cycle.

Note: Potassium chloride may be used instead of salt.

Other Benefits:

  • Plastic enclosure fits tightly to protect control components from outside elements.
  • The brine tank is equipped with overflow protection.
