GE Appliances Water Softener Specs — Grain, Iron & Warranty

Quick answer

GE Appliances's published softener lineup covers 4 models spanning 30,000 to 45,000 grains, all demand-initiated (metered) regeneration. Every figure below is captured from official GE Appliances sources with the link shown — match any model's grain rating against your requirement from the size calculator before comparing anything else.

GE Appliances softener lineup at a glance

GE Appliances is one of the few brands that publishes the full salt-dose capacity table in its install manuals — the same model delivers different grain capacities at different salt settings (see the spec notes below the table). That is exactly the rated-vs-usable capacity distinction our sizing method is built on, and it makes GE Appliances spec sheets unusually honest reading.

Every figure traces to an official GE Appliances source (linked per table); anything the sources don't state is marked "(to be verified)" rather than guessed.

How to read these specs against your sizing

Three checks before buying any GE Appliances 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 GE Appliances lineup regenerates on demand (metered), which tracks actual water use rather than a calendar — the feature that keeps salt bills honest.

Which GE Appliances tier fits which household

At 15 gpg (very common hard water), the GE Appliances lineup covers: a couple (needs ≈ 21,000 grains rated) → 30,000-grain; a family of four (≈ 42,000) → 45,000-grain; a family of six (≈ 63,000) → outside this lineup. Six-person households on very hard water generally outgrow single-tank retail units — a duplex system or the next brand tier up serves better. Different hardness moves these fast: every ±5 gpg shifts a typical family one tier — see the sizing chart for the full matrix.
