What should an operator do if hardness leakage is excessive immediately following a regeneration stage?

• A. Immediately Start The Rinse Stage
• B. Re-Run The Regenerative Stage
• C. Shut The Unit Down And Check The Media Level
• D. Check The Media Level And Then Redo The Backwash Cycle

Answer: (C)

When hardness shows up right after regeneration, the first priority is to verify the resin bed is in its proper place and height. If the media level is low or the bed has shifted, water can bypass the resin and carry hardness ions straight through, giving you a high hardness reading even though regeneration occurred. Shutting the unit down and checking the media level allows you to confirm that resin is present, properly packed, and at the correct height. If the level is low, you can refill to the correct mark and re-evaluate. If the bed has settled or appears damaged, you may need to address that before operating again. Starting the rinse, re-running regeneration, or redoing the backwash doesn’t address the immediate risk of resin bed displacement or loss, so they’re not the best immediate actions. Once the media level is confirmed (and corrected if needed), you can continue with proper startup procedures and further troubleshooting if hardness persists.
