Pump is running but there are large amounts of air bubbles coming from the return jet.

Safety First: Unplug the pump before loosening any hose connections.

• Check water level: Raise the pool water level so the intake fittings are well submerged and not drawing in surface air.
• Inspect suction hose: Look for cracks, pinholes, or flattened sections. Replace damaged Summer Waves hoses.
• Tighten clamps: Ensure all hose clamps on the suction side are snug but not crushing the hose.
• Service lid O-ring: Remove the pump lid, clean the O-ring and groove, and apply a thin layer of pool-safe silicone lubricant. Replace the O-ring if cracked or flattened.
• Re-prime: Fill the pump housing with water, reinstall the lid, and restart. Observe for reduction in bubbles.
