Softener is very noisy during backwash, with banging or water hammer in the pipes.

Safety first: Sudden pressure surges can stress plumbing; monitor for leaks.

• Check pressure: Measure mains pressure with a gauge. If above Kinetico's recommended maximum, install a pressure reducing valve (PRV) upstream.
• Secure pipework: Ensure pipes near the softener are properly clipped and supported to reduce movement.
• Install hammer arrestors: Fit water hammer arrestors near the softener or at problem fixtures to absorb shock.
• Schedule regeneration: Program regeneration to occur at night when water usage is low to minimise disturbance.

Warning: Persistent water hammer can damage both the softener and household plumbing; address promptly.
