Possible Causes

Clogged inlet screen, Fouled resin bed, Partially closed bypass valve, Undersized plumbing or softener for demand

How to Fix / Troubleshooting

Safety: Place the unit in bypass to restore normal pressure while diagnosing. Shut off water and relieve pressure before removing fittings.

  • Compare pressure: Note water pressure with the softener in bypass vs. in service. Significant drop in service indicates internal restriction.
  • Check bypass position: Ensure the WaterBoss bypass is fully in the 'service' position when using the softener.
  • Inspect inlet screen: Remove the inlet connection and check for sediment or debris on any inlet screen or filter. Clean as needed.
  • Evaluate resin condition: A heavily fouled resin bed can restrict flow. Use a resin cleaner or consider resin replacement if the unit is older.
  • Check plumbing size: Confirm that inlet/outlet piping matches the softener's connection size and is not reduced unnecessarily.
