Possible Causes

Damaged or unbalanced impeller, Pump not securely mounted to base, Misaligned plumbing putting stress on pump ports

How to Fix / Troubleshooting

Safety first: Turn off power before tightening mounts or adjusting plumbing.

  • Check mounting: Ensure the AquaJet pump base is firmly bolted to a solid pad. Tighten loose mounting bolts.
  • Inspect impeller: Open the pump housing and check the impeller for missing pieces or heavy buildup on one side. Replace if damaged.
  • Support plumbing: Add pipe supports or hangers so that the weight of the plumbing is not pulling on the pump unions.
  • Re‑test: After corrections, run the pump and observe. Persistent severe vibration may indicate internal motor issues requiring replacement.
