What the numbers mean
The flows are close: 11 GPM for the SS1, 10 GPM for the Matrixx. Capacity favors the Matrixx slightly, 35,000 against 32,000 grains. The real differences are salt, paperwork and coverage.
US Water Systems publishes the salt figure (3 lb and 33 gallons per regeneration on StackFlow), a WQA Gold Seal certified valve and NSF certified resin. SpringWell publishes neither a salt figure nor a certification. On warranty, 10 years on the Matrixx valve beats 5 years on SpringWell's electronic head, and US Water Systems gives a year to return it against six months.
