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.
Apply the correct source evidence
Confirm the supplier on the property water bill. Port St. Lucie’s public report applies to its Utility Systems customers; a mailing address does not prove supplier, and a private well needs its own testing. See the Port St. Lucie source guide before applying a report or selecting a treatment goal.
Review the 2025 Water Quality Report 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.
