Softener makes loud banging or hammering noises during regeneration

Safety first: No internal electrical work is required, but be cautious around moving pipework.

• Secure pipework: Check that inlet and outlet pipes are firmly clipped and not free to move and bang against walls.
• Check pressure: If possible, measure mains pressure. If it is above the Aqua Dial specification, consider installing a pressure reducing valve.
• Install water hammer arrestor: Fit a suitable hammer arrestor near the softener inlet to absorb shock.
• Verify plumbing size: Ensure the pipe size matches the softener connections and is not excessively reduced, which can increase velocity and noise.
