Sta-Rite pool pump vibrates excessively and may move on the equipment pad during operation.

Safety: Turn off power before adjusting pump mounting.

• Secure mounting: Ensure the Sta-Rite pump base is bolted to the pad using appropriate anchors. Tighten loose bolts.
• Level the pump: Use shims to level the pump base if the pad is uneven. A level pump reduces vibration and stress on plumbing.
• Eliminate cavitation: Check for suction restrictions (clogged baskets, closed valves) and air leaks that can cause cavitation noise and vibration. Correct as needed.
• Inspect impeller: If vibration persists, disassemble the wet end and inspect the impeller for broken vanes or debris causing imbalance. Replace a damaged impeller.
