WATER FIXERS SOFTENER MODEL • PREMIUM TWO-TANK SYSTEM
SmartSoft Water Softener
A premium high-capacity two-tank softener for homes with higher household demand and simultaneous flow.
Quick answer: SmartSoft uses 2.0 cu. ft. of 10% crosslink resin and is published at 48,000 grains at a 6 lb salt dose, with 14 GPM nominal and 18 GPM peak flow.
Water Fixers lists it as a typical fit for homes under 3,500 sq. ft. and households of 1–6 people, but final sizing should use measured hardness, actual household demand, simultaneous flow, plumbing conditions and installation space—not square footage alone.

SMARTSOFT AT A GLANCE
The four numbers to understand first
Typical household
1–6 people. Use as a starting range, not a stand-alone sizing rule.
Published capacity
48,000 grains at a 6 lb salt dose.
Published flow
14 GPM nominal / 18 GPM peak.
Resin
2.0 cu. ft. of 10% crosslink resin.
Maximum working pressure: 90 PSI. 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 SmartSoft instead of a smaller Water Fixers model?
Higher published flow
SmartSoft has the highest published nominal and peak flow in the current five-model Water Fixers lineup: 14 GPM nominal and 18 GPM peak. Higher published flow only helps when the home’s actual simultaneous demand and plumbing can use it.
Larger resin volume and salt storage
Its 2.0 cu. ft. of 10% crosslink resin and 350 lb published salt-storage capacity are the largest in the current lineup. That also means the two-tank system needs adequate installation and service space.
Metered up-flow control
The published control package includes an electronic valve, adjustable multi-cycle programming, proportional brining, variable reserve capacity, up-flow regeneration, a flow-meter totalizer and automatic regeneration.
SmartSoft is the premium high-capacity option in the current lineup. If the home does not need its capacity or flow, compare SoftFlo C, SoftFlo S, SoftFlo SE and SoftFlo SEC before choosing.

SIZING BEFORE SELECTION
Do not choose SmartSoft from square footage alone
The “under 3,500 sq. ft. / 1–6 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
SmartSoft 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.
SERVICE ACCESS MATTERS
Plan for access after installation day
The bypass, control valve, brine components and drain routing should remain reachable so the system can be maintained and diagnosed later.
Planning a new or replacement system? Use the installation page. For routine care, use maintenance. If an existing softener is leaking, not regenerating or allowing hardness to return, use the repair page.
COMPARE THE FIVE-MODEL LINEUP
SmartSoft is the high-capacity 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.

SMARTSOFT 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 14 GPM nominal flow appropriate?
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 6 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.
