Start With the Easy Stuff

Low water level, a cracked pump lid O-ring, or a loose union can introduce air. Fix the obvious before assuming underground plumbing.

  • Water level halfway up the skimmer opening
  • Clean and lubricate the pump lid O-ring
  • Tighten unions and check drain plugs for seepage

When It Is Not the Pad

If you have persistent bubbles and weak prime, especially when a specific suction line is used, you may be looking at a suction-side leak. Diagnose systematically line by line.
