Amfa4000 is very noisy during regeneration (loud banging or hammering sounds)

Safety first: High pressure can cause sudden pipe movement. Do not stand directly over unsupported pipes during testing.

• 1. Check pipe supports: Ensure all pipes around the Amfa4000 are securely clipped to walls or joists to reduce movement.
• 2. Measure pressure: Use a gauge to check mains pressure. If high, install or adjust a pressure reducing valve upstream.
• 3. Install water hammer arrestor: Fit a hammer arrestor near the Amfa4000 inlet if hammer persists.
• 4. Verify regeneration time: Schedule regeneration for night hours when water usage is low to minimize disturbance.

If noise continues despite proper pressure and supports, internal valve components may be slamming shut and a valve head service may be required.
