What should I record first?
A useful proposal starts with a hardness measurement, source identification and peak household flow. A grain rating on a sales sheet is not a complete sizing method, and the same tank can have different usable capacity at different salt settings.
What changes the recommendation?
Review resin volume, salt dose, expected regeneration frequency and the manufacturer's operating limits. Include any measured iron or other incoming-water condition that could change pretreatment or resin suitability.
What should the service scope include?
Have the installer identify isolation, bypass, drain and air gap, power, salt-loading clearance and any irrigation separation. Agree on startup settings and a before-and-after hardness check, and retain the configuration for future service.
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.
