Regeneration Frequency Input Worksheet
Back to Water Softener Regeneration: Frequency, Stages and Checks
Use at least two naturally occurring cycles. Do not start an extra cycle just to fill the worksheet.
A. Verified inputs
| Input | Value | Unit | Source/manual page | Date | Confidence/notes |
|---|---|---|---|---|---|
| Incoming untreated hardness | |||||
| Documented capacity at configured dose | grains | ||||
| Configured salt dose | lb/cycle or manual unit | ||||
| Regeneration type | |||||
| Reserve type and value | |||||
| Day override | |||||
| Scheduled regeneration time | |||||
| Recent softened-water use | gallons/day or interval | ||||
| Known bypassed uses |
B. Directional calculation
- Daily hardness load = hardness gpg × softened gallons/day = __________ grains/day
- Gross treatment volume before controller reserve = capacity grains ÷ hardness gpg = __________ gallons
These are audit values, not a universal cycle forecast. The controller's meter, reserve, override, sensor, and model logic still apply.
C. Observed cycles
| Cycle | Trigger/display | Start | Return to service | Days since prior | Gallons since prior | Water use/context | Salt trend | Treated hardness result | Match manual? |
|---|---|---|---|---|---|---|---|---|---|

D. Evidence checks before calling frequency abnormal
- [ ] Exact model/manual confirmed
- [ ] Untreated hardness and unit verified
- [ ] Capacity remains paired with configured salt dose
- [ ] Regeneration type, reserve, and override documented
- [ ] Actual water use checked rather than estimated by household size alone
- [ ] Toilets, faucets, and unexplained metered flow checked
- [ ] Power outage and controller clock history checked
- [ ] Source-water change considered
- [ ] No constant drain flow, leak, overflow, error, or stalled stage
Conclusion: ☐ explained by documented load/control ☐ insufficient evidence ☐ troubleshooting needed ☐ urgent service condition
