The smart, economical way to enjoy the best water possible.

How the TC-CAB Series System Works

Step 1: Water enters RainSoft's exclusive rugged control valve and flows down through the resin tank.

Step 2: The water is filtered and treated as it passes through the special "ion exchange" resin. Hardness ions are ionically retained both in and on the resin. The optional carbon bed further polishes and clarifies the water.

Step 3: Once completely conditioned, the water exits the resin tank through the riser pipe and out the control valve.

Step 4: At predetermined intervals, the unit begins a regeneration process. Using salt as a regenerant, the retained hardness ions are flushed out of the system and down the drain. The unit then prepares itself for the next conditioning cycle.

Other Benefits

  • All plastic enclosures fit tightly to protect control components from outside elements.
  • An ultraviolet inhibitor prevents degradation of materials caused by sunlight in outside installations.
  • The brine tank is equipped with overflow protection to protect against overflow due to power outages during regeneration.
