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: Close inlet and outlet valves and relieve pressure before removing any plumbing connections.

Step-by-step:

  • Bypass test: Place the AquaUnique softener in BYPASS. If pressure improves, the restriction is in the softener.
  • Clean screens: Remove and rinse inlet and outlet screens or filters on the control valve.
  • Backwash resin: Manually start a regeneration and ensure the backwash stage runs for the full programmed time to flush sediment.
  • Check valve positions: Confirm all service valves are fully open.

When to call a technician: If pressure remains low in SERVICE but normal in BYPASS, the resin bed may be severely fouled or the control valve internally restricted and may need professional service.
