Softener causes noticeable pressure drop or low flow in the house when in service.

Safety: Turn off water and relieve pressure before removing screens or opening the valve head.

• Check valves: Ensure bypass and isolation valves are fully open and correctly positioned.
• Clean screens: Remove and rinse inlet and outlet screens on the Hansgrohe valve head to clear sediment.
• Backwash test: Initiate a manual regeneration and observe the backwash flow. Weak backwash may indicate severe resin fouling or plumbing restriction.
• Resin cleaning: If iron fouling is suspected, use a resin cleaner compatible with Hansgrohe systems according to product instructions.
• Resin replacement: If flow remains poor and resin is heavily fouled or compacted, replace the resin bed.
