Pump runs but water flow surges up and down; jets alternate between strong and weak.

Safety first: Turn off the pump before cleaning baskets or adjusting hoses.

• Clean all baskets: Remove and thoroughly clean skimmer and pump baskets.
• Bleed air: After priming, run the pump and open any air bleed valves on the filter until water flows steadily.
• Inspect hoses: If using flexible suction hoses (e.g., from a vacuum), check for kinks or soft spots that collapse under suction.
