How to Fix / Troubleshooting

Safety: Work carefully around pressurized lines and secure ladders or supports as needed.

Steps:

  • Check flow control: Verify the AquaClean backwash flow control insert matches the tank size. Replace with correct size if oversized.
  • Measure pressure: Reduce inlet pressure with a PRV if above recommended range.
  • Secure piping: Add clamps and supports to stabilize vibrating pipes.
  • Drain line sizing: Ensure the drain line diameter and length meet AquaClean specifications to avoid restriction.

Adjusting flow and securing plumbing typically resolves vibration issues.
