Waterway pool pump is unusually loud compared to when it was new, even though it still works.

Safety: Turn off power before tightening or adjusting anything.

• Tighten hardware: Check all mounting bolts on the Waterway pump base and motor. Tighten any loose fasteners.
• Inspect for rubbing: Open the pump housing and check that the impeller is not rubbing on the diffuser or housing. Adjust or replace worn parts.
• Check bearings: Listen closely at the motor for bearing noise. If present, plan for motor replacement.
• Add vibration isolation: Install rubber pads under the pump base to reduce transmitted noise and resonance.
