Water softener is noisy during regeneration (loud banging, whistling, or humming)

Safety: Close inlet valve slowly to avoid water hammer. Depressurize before adjusting piping.

• Check pressure: Measure inlet pressure. If above Idrobase limits, install or adjust a pressure reducing valve.
• Secure pipes: Add or tighten pipe clamps and supports near the softener to reduce vibration and banging.
• Inspect drain line: Ensure the drain hose is not partially blocked and is properly sized and routed to avoid backpressure.
• Adjust cycle times: In some models, backwash and rinse flow rates can be adjusted. Reduce flow slightly if noise is excessive, staying within manufacturer limits.
