Softener causes water hammer or banging noises in pipes during regeneration.

Safety: Be cautious when adjusting pressure regulators; excessive pressure can damage plumbing.

• Measure pressure: Use a gauge to check household water pressure. If above Hansgrohe's recommended maximum, adjust or install a pressure reducing valve.
• Secure pipes: Inspect nearby plumbing and secure loose pipes with proper clamps to reduce movement.
• Install arrestors: Consider installing water hammer arrestors near the softener or at problem fixtures.
• Regeneration timing: Schedule regeneration for nighttime when fewer fixtures are in use to minimize noticeable noise.
