Possible Causes

High incoming water pressure, Rapid valve port changes, Inadequate pipe support, No water hammer arrestor

How to Fix / Troubleshooting

Safety first: High pressure can damage plumbing. Consider using a pressure gauge.

  • Measure pressure: Use a gauge on a nearby tap to check static pressure. If above manufacturer recommendations, install a pressure reducing valve.
  • Secure pipes: Ensure pipes near the Water2Buy unit are properly clipped and supported.
  • Install hammer arrestor: Fit a water hammer arrestor on the line feeding the softener if banging persists.
  • Adjust cycle times: If possible, slightly increase backwash and rinse times to reduce sudden flow changes.
