Before/After Water Hardness Test Worksheet
Back to How to Test Water Hardness Before and After a Softener
Print one sheet per comparison. This worksheet is for hardness only; it is not a drinking-water safety record.
Test purpose
- [ ] Establish incoming hardness
- [ ] Check current hardness reduction
- [ ] Obtain a value for a model-specific settings procedure
- [ ] Document a result before and after service
- [ ] Other: ______________________________________________
Context
| Field | Record |
|---|---|
| Date and local time | |
| Water source: public system/private well | |
| Utility or source change known? | |
| Softener model/manual reference | |
| Softener mode: service/regeneration/unknown | |
| Time since last regeneration, if known | |
| Bypass position: service/bypass/unknown | |
| Recent salt, setting, service, outage, or plumbing change |
Test method
| Field | Record |
|---|---|
| Method: strip/drop titration/laboratory/professional/other | |
| Product, provider, or method name | |
| Lot and expiration, if shown | |
| Reported unit | |
| Stated increment or resolution | |
| Method range | |
| Sample and reading instructions followed |
Sample A — untreated water
| Field | Record |
|---|---|
| Exact outlet or sampling point | |
| How upstream location was verified | |
| Cold water confirmed | |
| Outlet preparation used from method instructions | |
| Original result and unit | |
| Repeat result and unit | |
| Range, inequality, or out-of-range indicator | |
| Notes or uncertainty |
Sample B — treated water
| Field | Record |
|---|---|
| Exact outlet or sampling point | |
| How downstream location was verified | |
| Cold water confirmed | |
| Outlet preparation used from method instructions | |
| Original result and unit | |
| Repeat result and unit | |
| Range, inequality, or out-of-range indicator | |
| Notes or uncertainty |
Comparison
| Field | Record |
|---|---|
| Untreated result in original unit | |
| Treated result in same unit | |
| Converted untreated value, if needed | |
| Converted treated value, if needed | |
| Did the method resolve a difference? | |
| Does the result agree with a repeat? | |
| Relevant manual criterion, if any | |
| Interpretation limited to what the comparison supports |
Decision
- [ ] Keep as baseline record
- [ ] Repeat with fresh materials
- [ ] Verify plumbing/sample points
- [ ] Check the model manual
- [ ] Obtain a professional or laboratory hardness result
- [ ] Contact a qualified water-treatment professional
- [ ] Use a separate water-safety testing pathway
