Possible Causes

Clogged inlet/outlet screens, Fouled resin bed with iron or sediment, Undersized softener for flow demand, Partially closed bypass or shutoff valves

How to Fix / Troubleshooting

Safety first: Turn off water and relieve pressure before opening any plumbing or valve fittings.

  • 1. Compare pressure in bypass vs. service: Place the SoftPro bypass in Bypass and check flow at a faucet. If flow improves significantly, the restriction is in the softener.
  • 2. Inspect inlet/outlet screens: Shut off water, relieve pressure, and remove the inlet and outlet fittings at the valve head. Clean any mesh screens or flow restrictors of debris.
  • 3. Check valve and piping: Ensure the bypass and any upstream/downstream shutoff valves are fully open. Straighten any kinked flex connectors.
  • 4. Evaluate resin fouling: If the system is older or on iron-bearing water, the resin may be clogged. Perform an iron/resin cleaner treatment per SoftPro guidelines. If flow does not improve, consider replacing the resin bed.
  • 5. Confirm sizing: If your household has high simultaneous demand (multiple showers, irrigation), verify that the SoftPro unit is sized appropriately. An undersized unit may need upgrading.
