Hayward PowerFlo pump will not hold prime after being off overnight; must be manually primed each day.

Safety first: Turn off the pump before inspection.

• Check lid and drain plugs: Service the PowerFlo lid O-ring and ensure drain plugs are tight with good gaskets.
• Inspect check/foot valve: If your system uses a check valve or foot valve on the suction line, inspect or replace it to prevent water from draining back to the pool.
• Lower suction line (if possible): Ensure suction plumbing is routed to minimize high points where air can accumulate.
• Prime and test: Fully prime the PowerFlo, then shut it off and observe for air entering the basket over time. Address any visible leaks.
