Side-by-side comparison
48,000 vs. 64,000-Grain Softener
Same one-tank softening and carbon filtration design, two sizes. Here’s what changes when you step up to the larger tank.
| Feature | 48,000 grains | 64,000 grains |
|---|---|---|
| Softening capacity | 48,000 grains | 64,000 grains |
| Media tank (D × H) | 10" × 54" | 12" × 52" |
| Media volume | 1.5 cu ft resin | 2 cu ft resin + carbon |
| Valve flow rate | 30 GPM* | 28 GPM |
| Service / system flow | 27 GPM* | 27 GPM at 15 PSI drop |
| Brine / salt tank | 15" × 35" square | 15" × 35" square |
| Filtration | Coconut-shell carbon in the same tank | Coconut-shell carbon in the same tank |
| Regeneration | Metered, based on water use | Metered, based on water use |
| Connections | 1" NPT, 1" bypass | 1" NPT, 1" full-flow bypass |

Key differences
What the bigger tank changes
More capacity between regenerations
The 64,000-grain tank holds about a third more softening capacity, so it regenerates less often — using less salt and water per cycle over time in high-use homes.
Wider tank, more media
The larger option uses a 12" tank with about 2 cu ft of media versus a 10" tank with 1.5 cu ft. It needs a little more floor space.
Same everyday flow
Both deliver about 27 GPM through the house, so shower and faucet pressure feel similar. The difference is how long they go between regenerations.
Same design
Both combine softening resin and carbon filtration in one tank with the same salt tank and metered valve.
Which one fits
Choosing your size
The 48,000-grain option fits…
- Most single-family homes
- City water with up to three bathrooms
- Typical household water use
The 64,000-grain option fits…
- Homes with four or more bathrooms
- Larger households (around eight or more people)
- Very hard water that would make a smaller tank regenerate often
