What should I record first?
Keep the existing model, age if known, service history and measured hardness together. The strongest reason to replace is an identified limitation, repeated failure or unavailable parts, rather than the age of the tank by itself.
What changes the recommendation?
Compare resin volume, usable capacity, flow rating, regeneration controls and salt use under the same household assumptions. Reusing a loop does not prove the drain, bypass or electrical arrangement is suitable for a new valve.
What should the service scope include?
Ask for removal and disposal, plumbing changes, startup settings, parts and labor warranty and recurring supplies in writing. Specify how treated-water hardness will be verified before treating the project as complete.
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.
