City Utilities of Springfield filter and testing guidance
Use this only as an interim protection layer when replacement is not immediate and the utility-specific next step is still unresolved.
Filters and testing are interim safety layers. They are not equivalent to a utility-confirmed full replacement path.
Use this only when replacement is not immediate: filter guidance sits below inventory, notice, and replacement decisions. It is not a substitute for line replacement.
Use local utility guidance, then narrow to certified interim protection.
Maintenance tips
Use a certified filter as an interim protection step, not as a replacement for line replacement.
Use testing when it changes the next action or clarifies uncertainty.
Return to the utility lookup if the service-line status is still unclear.
Testing should change the next action, not distract from the utility record.
