Hayward PowerFlo pump basket fills with air bubbles while running; return jets show constant bubbles.

Safety first: Turn off the pump before tightening fittings or removing lids.

• Raise water level: Ensure pool water is high enough to prevent a vortex in the skimmer.
• Service lid O-ring: Clean, lubricate, and if necessary replace the PowerFlo lid O-ring.
• Check suction fittings: Tighten unions and hose clamps on the suction side. Replace any cracked hoses or fittings.
• Test with water hose: With the pump running, gently spray water over suspected suction joints. If bubbles decrease when spraying a joint, that joint is likely leaking air and should be repaired.
