WHAT MAKES THIS MODEL DIFFERENT
SoftFlo S in the five-model lineup
SoftFlo S separates the resin tank from the brine tank and adds an electronic valve with Water Saving Factors. It remains a fixed-cycle, down-flow system and is the most compact two-tank choice in the lineup.
Installation fit matters
Published equipment information: Brine tank: 30 in. H × 14 in. D; resin tank: 9 in. D × 48 in. H. Salt storage is 200 lb; connections are 1 in. inlet and outlet ports; bypass configuration is 3/4 in. and 1 in. adapters. Confirm clearances, drain routing, pressure and service access before installation.
Choose it when…
- The published home and household range fits the property.
- Two-tank system fits the available space.
- 7 GPM nominal flow is appropriate for expected simultaneous demand.
- Fixed-cycle programming plus Water Saving Factors matches the preferred control strategy.
- Local testing, installation and service are part of the plan.
