The starting model uses two alternating 18 × 63-inch media tanks. One tank regenerates at a time. Confirm these settings against the actual resin load and control-valve program.

Domestic gallons are calculated as monthly Domestic Water Cost ÷ blended rate × 1,000. Monthly car volume is then used to calculate gallons and domestic water cost per car. The WaterIQ™ estimate applies a fixed 66.7% reduction to the entered hardness load; it does not represent a laboratory hardness result or a guaranteed savings amount.
