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.
Use the correct Palm City source
Confirm the supplying account or household well. Martin County’s 2025 Drinking Water Quality Report, public system4431891, is public-system context and not an individual tap or private-well result. The County utility map helps identify the account. A separate irrigation well may feed landscaping rather than the household. Source reviewed October 3, 2026.
