Sta-Rite pool pump is unusually loud with a high-pitched whine, especially at higher speeds on variable-speed models.

Safety: Turn off power before touching the pump.

• Isolate vibration: Install rubber isolation pads under the Sta-Rite pump base to reduce noise transmission into the pad.
• Adjust speed settings: On variable-speed models, slightly adjust programmed RPMs up or down to avoid resonance frequencies that amplify noise.
• Check bearings: Listen closely at the motor body. If the whine is accompanied by roughness or grinding, the bearings are likely worn and the motor should be replaced.
• Secure plumbing: Ensure pipes are properly supported to prevent them from acting as soundboards.
