Source: store.afwfilters.com (verified 2026-07-07) · corroborated by affordablewater.us. AFWFilters product page (SKU WS48-56SXT, the exact "Fleck 5600SXT 48,000 Grain Water Softener Digital SXT Metered Whole House System") confirms verbatim: 48,000 grain / 1.5 cubic feet of high capacity 8% cross linked resin, ion-exchange operation ("Using ion exchange process this system removes the calcium and magnesium"), "up to 12 gpm service flow rates (28 GPM peak)", a 5-year valve warranty and a 10-year tank warranty, priced $901.00 standard / $759.00 sale. AffordableWater.us (SKU AW-S56SXT48) corroborates the same exact 48,000-grain / 1.5 cu ft model at $799.00 (Current/Original price verbatim), with a 10-year 10"x54" resin-tank warranty and a rated flow of 13 gpm at 15 psi drop. Salt efficiency per 1,000 grains, iron-removal ppm, and NSF/ANSI certification are not stated on either page (the resin is "tested and certified by the Water Quality Assn." — a WQA listing, not NSF/ANSI), so those specKeys are null. msrpUsd is also null: neither page states a manufacturer's suggested retail price (AFWFilters' MSRP field is blank; the $799 is AffordableWater's selling price, captured in priceUsd) and no manufacturer MSRP exists for this assembler-packaged system. Model verified as the exact 5600SXT 48,000-grain metered build on both pages, not a sibling capacity or variant.
