Test the water you are adding, not just the pool
Refill water explains recurring hardness, stain, and TDS problems
- Refill water explains recurring hardness, stain, and TDS problems
- Current observations, recent test results, and equipment or label details this playbook asks for.
- The issue involves electricity, gas, structural movement, missing drain covers, contamination, or work outside owner-safe inspection.
Test fill-water pH, CH, and metals when relevant
Owners often keep correcting the same issue without testing the source that keeps reintroducing it.
Compare recurring problems against refill behavior
Sometimes the pool keeps drifting because the refill water keeps reintroducing the same issue.
Treat wells and disaster recovery as special cases
Private well water and post-flood water situations need more caution, not less.

Source water pre-treatment
Use the pre-treatment guide for hose-end filters, alternate fill sources, softened-water caveats, and repeat-fill strategy.
Draining and refill planning
Use the drain guide when the source water profile tells you dilution or staged replacement is the better answer.
Photo-Driven Stain Identification Helper
Use the photo helper when refill-water clues are showing up as stains instead of just numbers.
Well water recurring treatment decision tree
Use the recurring-treatment decision tree when the fill source is a private well and the same burden keeps coming back.
EPA secondary drinking water standards
EPA guidance on nuisance metals and water-quality characteristics such as iron, manganese, copper, chloride, and TDS.
EPA well-water contaminants guidance
EPA overview of potential well-water contaminants and why private-well owners need testing and source awareness.
