Possible Causes
Partially clogged inlet screen, Fouled venturi, Resin fines plugging distributor, Partially closed bypass or shutoff valves
How to Fix / Troubleshooting
Safety first: Turn off power and close the main water supply before disassembly.
Step-by-step checks:
- 1. Bypass test:
- Place the softener in bypass. If pressure improves, restriction is inside the softener.
- 2. Inlet screen and venturi:
- Inspect and clean the inlet screen (if equipped) and venturi/nozzle assembly.
- 3. Resin condition:
- If the unit is old and resin is breaking down, fines can clog the distributor and screens.
- Consider replacing the resin bed and cleaning the distributor tube.
- 4. Valves:
- Ensure all shutoff valves before and after the softener are fully open.
