I have bubbles in the pool return. No air in the pump tank w/strainer. No "extra" air in filter when I bleed it. I've already replaced the o-ring in the pump basket and water level is fine.
I do have a small leak on the return side in my water clarifier that I've never used. Could a leak cause air to be pulled in? What else should I be looking at? I'm stumped!
Hesitant to call a professional just yet.
