Aquasana softener is noisy during regeneration (loud banging, knocking, or whistling)

Safety first: High water pressure can damage plumbing. Use caution when adjusting valves.

Steps to reduce noise:

• 1. Check water pressure: Use a pressure gauge on a nearby faucet. If pressure exceeds 80 psi, install or adjust a pressure-reducing valve.
• 2. Secure plumbing: Ensure pipes around the Aquasana softener are properly strapped and supported to reduce banging.
• 3. Inspect drain line: Confirm the drain line is not restricted and is properly secured to prevent whipping during discharge.
• 4. Adjust regeneration time: Schedule regeneration for overnight hours when noise is less disruptive.
• 5. If noise persists: Internal valve components may be worn. A technician may need to service or replace the control valve.
