Air blower runs but produces weak or no bubbles

Safety first: Turn off power before inspecting blower and air lines.

• 1. Inspect air intake:
  • Locate the blower air intake and ensure it is not blocked by debris.
• 2. Check for water in lines:
  • Listen for gurgling; if water is present, the blower or check valve may have failed.
• 3. Inspect hoses:
  • Check air hoses for kinks or crushing.
• 4. Check valve:
  • Locate and test the air check valve; replace if stuck or leaking.
• 5. Replace blower if damaged:
  • If the blower has ingested water or is noisy/weak, replace it with a compatible unit.
