Pump vibrates excessively and may move on the pad during operation.

Safety First: Turn OFF power before touching the pump or plumbing.

• Check for air in pump: Look through the lid for large air pockets. Resolve suction leaks and ensure proper priming to reduce cavitation‑induced vibration.
• Inspect impeller: Disassemble the wet end and clean any debris from the impeller that could cause imbalance.
• Verify alignment: Ensure the motor mounts squarely to the Rheem pump housing and that all bolts are evenly tightened.
• Secure mounting: Tighten anchor bolts securing the pump to the equipment pad. Replace crumbling pads or add vibration‑damping pads if necessary.
• Check for bent shaft: If vibration persists, the motor shaft may be bent; replace the motor assembly.
