I am trying to sort out a suction side air leak. I have read about the "vortex in skimmer" issue meaning water is too low. My water seems high enough, but in my deep end skimmer I get very circular movement of water that I would not quite classify as a "vortex". Is this normal, or is this what is referred to as a "vortex". Will water move circularly in a skimmer normally?
Also I have a Jandy Check valve. If it is working correctly. shouldn't I not lose prime when the pump is off?
Is it normal when you remove the skimmer pot lid for the water to rush out of the basket?
