SpringWell Water Softener Specs — Grain, Iron & Warranty
SpringWell water softener models compared: grain capacity, iron limits, flow and warranty from official sources, linked line by line.
Quick answer
SpringWell's published softener lineup covers 3 models spanning 32,000 to 80,000 grains, all demand-initiated (metered) regeneration. Every figure below is captured from official SpringWell sources with the link shown — match any model's grain rating against your requirement from the size calculator before comparing anything else.
Manufacturer datasheet · 2026-11-06SpringWell softener lineup at a glance
SpringWell keeps the lineup focused: 3 models across a tight grain range. The table below is short enough to compare directly against the rated capacity the size calculator gives you — one read, no marketing in between.
Every figure traces to an official SpringWell source (linked per table); anything the sources don't state is marked "(to be verified)" rather than guessed.

Manufacturer datasheet · 2026-11-06How to read these specs against your sizing
Three checks before buying any SpringWell model: first, get your required rated capacity from the size calculator (hardness + household + iron); second, verify the model's rated iron limit exceeds your tested iron — same-tier models differ here more than anywhere else; third, confirm service flow rate covers your peak simultaneous use (bathrooms × 3–4 GPM as a working figure). The warranty column rewards a slow read: tank, valve and electronics terms are listed separately by most brands and they are not equal.
Salt and maintenance context
Whatever the tier, running cost is mostly salt: expect on the order of 40–80 lb per month for an average household (the regeneration calculator computes it for your exact load), plus an occasional resin cleaner where iron is present. Every model in the current SpringWell lineup regenerates on demand (metered), which tracks actual water use rather than a calendar — the feature that keeps salt bills honest.
Which SpringWell tier fits which household
At 15 gpg (very common hard water), the SpringWell lineup covers: a couple (needs ≈ 21,000 grains rated) → 32,000-grain; a family of four (≈ 42,000) → 48,000-grain; a family of six (≈ 63,000) → 80,000-grain. Different hardness moves these fast: every ±5 gpg shifts a typical family one tier — see the sizing chart for the full matrix.

FAQ
Is a SpringWell water softener the right size for my home?
SpringWell sells multiple grain tiers, so the question is which tier, not which brand. Size first — hardness × household on the [size calculator](/#calculator) — then check the grain column below: the lineup spans 32,000–80,000 grains, and step one tier up if you are between sizes or have iron.
Where do these SpringWell specifications come from?
Every figure is captured from SpringWell's own published material — official product pages, spec sheets and installation manuals — with the source link shown under each table and a capture date. Nothing on this page comes from retailer listings or third-party claims.
Why do some fields say (to be verified)?
When SpringWell doesn't publish a figure for a field — a flow rating, a salt dose — the cell stays marked rather than estimated. The missing number changes nothing about the specs that are published, and the [regeneration calculator](/regeneration-calculator) works from rated capacity, which every model states.
