Water pressure in the house drops significantly when water passes through the Aquabion softener.

Safety first: Close inlet/outlet valves and relieve pressure before disassembling any plumbing.

• Check bypass: Ensure the Aquabion bypass valve is fully in the service position. Test pressure with the unit in bypass; if pressure improves, the restriction is within the softener.
• Clean inlet screen: Remove the inlet union and clean the inlet filter screen of sediment.
• Backwash resin: Manually initiate a regeneration and allow a full backwash cycle to loosen the resin bed. If pressure does not improve, the resin may be fouled or the distributor may be blocked.
• Inspect resin tank internals: Advanced users can remove the control head and inspect the upper and lower distributors for blockage. Severe fouling may require resin replacement.

Warning: Do not increase house pressure above Aquabion specifications to compensate; this can damage plumbing and the softener.
