Morton Insufficient Capacity / Undersized Programming

Water is slightly hard near the end of the day or before the next scheduled regeneration, but soft immediately after regeneration.

Possible Causes

Hardness set too low, Household water usage higher than programmed, Incorrect grain capacity setting, Flow meter not registering all usage

How to Fix / Troubleshooting

Safety first: No internal disassembly is required; adjustments are made via the control panel.

  • Recheck hardness and usage: Confirm actual water hardness and estimate daily water use (typically 60–75 gallons per person per day).
  • Adjust hardness setting: Increase the programmed hardness by 10–20% to provide a safety margin, especially if iron is present.
  • Adjust capacity or regeneration frequency: On Morton units with adjustable capacity, reduce the capacity setting so the unit regenerates more frequently, or change the regeneration mode (e.g., from time-clock to demand if available).
  • Verify flow meter operation: Ensure the turbine flow meter is accurately counting water usage. If it intermittently sticks, clean or replace it.
  • Monitor results: After adjustments, test water hardness at different times of day over several days to confirm consistent softening.
