WATER FIXERS SOFTENER MODEL • TWO-TANK SYSTEM
SoftFlo S Water Softener
A straightforward two-tank softener for smaller households that need more flow than the compact SoftFlo C.
Quick answer: SoftFlo S uses 1.0 cu. ft. of 8% crosslink resin and is published at 24,000 grains at a 9 lb salt dose, with 7 GPM nominal and 10 GPM peak flow.
Water Fixers lists it as a typical fit for homes under 1,800 sq. ft. and households of 1–4 people, but final sizing should use measured hardness, actual household demand, simultaneous flow, plumbing conditions and installation space—not square footage alone.
Model-page role: This page is for SoftFlo S specifications, fit and ownership guidance. Installation, maintenance and repair have their own service pages.
SOFTFLO S AT A GLANCE
The four numbers to understand first
Typical household
1–4 people. Use as a starting range, not a stand-alone sizing rule.
Published capacity
24,000 grains at a 9 lb salt dose.
Published flow
7 GPM nominal / 10 GPM peak.
Resin
1.0 cu. ft. of 8% crosslink resin.
Maximum working pressure: 90 PSI. The published equipment figures describe the model; they do not replace a property-specific check of hardness, pressure, plumbing, drain routing, service clearance and peak-use demand.
WHERE IT SITS IN THE LINEUP
Why choose the SoftFlo S instead of the compact SoftFlo C?
Separate resin + brine tanks
SoftFlo S moves from the compact cabinet format to a two-tank layout. That creates a different installation footprint and gives it a 200 lb published salt-storage capacity.
More published flow
SoftFlo S is listed at 7 GPM nominal / 10 GPM peak, compared with 5 / 8 GPM on SoftFlo C. Flow demand still needs to be matched to the actual home.
Electronic metered control
The published control package includes a digital electronic valve, flow-meter totalizer, automatic regeneration and Water Saving Factors.
SoftFlo S is still the smaller two-tank option in the five-model lineup. If household demand or simultaneous flow is higher, compare SoftFlo SE, SoftFlo SEC and SmartSoft before choosing.

Confirm the written warranty, exclusions, registration requirements and labor terms in effect at purchase.
Installation clearance: leave practical room for the control valve, salt loading, bypass operation, drain/brine routing and future service. Final fit should be checked at the property.
SIZING BEFORE SELECTION
Do not choose SoftFlo S from square footage alone
The “under 1,800 sq. ft. / 1–4 people” range is useful for orientation, but a softener is really being asked to handle a hardness load and a flow demand.
Water Fixers should confirm the water hardness, household use, likely simultaneous fixtures, current plumbing and installation conditions before treating the published household range as the final answer.
MATCH THE EQUIPMENT TO THE PROBLEM
SoftFlo S is a hardness-treatment model—not a universal water-treatment system
Hardness / scale goal
Ion-exchange softening is the relevant whole-house treatment path when hardness is confirmed and scale reduction is the goal.
Taste, odor or sediment
Do not assume those symptoms are solved by a softener. Testing and filtration may be the right path instead of—or in addition to—softening.
Drinking-water goals
Point-of-use drinking-water concerns may call for reverse osmosis or another treatment selected for the actual water-quality target.
OWNERSHIP + SERVICE
Plan for access after installation day
A product page should not stop at the purchase decision. The bypass, control valve, brine components and drain routing should remain reachable so the system can be maintained and diagnosed later.
Water Fixers keeps installation, maintenance and repair intent on separate owner pages so customers can go directly to the right next step.
COMPARE THE FIVE-MODEL LINEUP
SoftFlo S is one option—not the default for every home
Use these published ranges to understand where each model sits, then size from the actual water and household demand. Do not assign models by city or square footage alone.

SOFTFLO S FIT CHECK
Questions worth answering before you choose it
Is hardness actually confirmed?
Start from a current hardness result or other reliable property-specific information rather than choosing a softener from symptoms alone.
Is 7 GPM nominal flow enough?
Think about simultaneous showers, faucets, appliances and the home’s plumbing. Peak flow is not a substitute for realistic service-flow planning.
Does the two-tank layout fit?
Verify room for both tanks, salt loading, bypass access, control-valve service and appropriate drain/brine routing.
Does the capacity fit the hardness load?
Capacity is stated at a 9 lb salt dose. Final regeneration expectations depend on hardness, water use and programmed settings.
Do you need different treatment too?
Odor, sediment, staining or drinking-water goals may require testing and another treatment path rather than a larger softener.
How will the system be serviced later?
Keep maintenance access and the repair path in mind before equipment is placed tightly against walls or other mechanical systems.
