Softener causes a loud banging or hammering noise in the pipes during regeneration.

Safety first: Use caution when working around pressurized plumbing. If you are not comfortable measuring pressure, contact a professional.

Step-by-step:

• 1. Measure water pressure: Attach a pressure gauge to a nearby hose bib or faucet. If static pressure exceeds AquaHouse specifications (often ~80 psi), install or adjust a pressure-reducing valve.
• 2. Secure plumbing: Check that pipes near the softener are firmly strapped and not free to move excessively.
• 3. Install hammer arrestors: If hammer persists, install water hammer arrestors on the inlet and/or near quick-closing fixtures.
• 4. Check valve transitions: Ensure the AquaHouse control valve is not cycling abnormally fast due to a control fault; update firmware or replace the control board if necessary.
