What should I record first?
Different standards and listed claims address different purposes. A claim for one substance does not establish removal of every substance, and a certified component is not automatically proof for the complete assembled installation.
What changes the recommendation?
Ask for the complete model identifier and a current listing or supported performance evidence for the target. Compare rated flow, capacity and maintenance conditions with the actual use. A sales phrase such as pure water is not a substitute for that record.
What should the service scope include?
Keep the listing and instructions with the quote. If the water findings change, recheck whether the existing product still addresses the target. A field TDS display or an aesthetic improvement does not independently verify every health-related reduction claim.
Apply the correct source evidence
For a Jupiter Farms household well, use property-specific sampling. Palm Beach County well-program guidance does not supply a universal chemistry result, and a Jupiter municipal report cannot characterize a private well. See the Jupiter Farms source guide before applying a report or selecting a treatment goal.
Review EPA private-well guidance for the appropriate source boundary. Source review: October 4, 2026. This guide provides decision questions; equipment selection and any safety-related interpretation require appropriate measurements and qualified advice.
