What should I record first?
Find the cartridge or media model, installation date, instructions and original reason for treatment. Color alone is not a reliable replacement clock for every filter, and a tank sold as low-maintenance may still need valve, media or performance checks.
What changes the recommendation?
Compare the recommended interval with actual water use, pressure drop and the target parameter. Cartridge replacement, media service and valve repair are separate tasks and should appear separately in a quote.
What should the service scope include?
Ask what will be checked before and after the work, who supplies consumables and whether sanitizing or startup flushing is required by the maker. Keep dates and results in a service log rather than relying on an unspecified lifetime 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.
