The pool has a Doughboy Skim-Line Deluxe skimmer. When the pump is run with the skimmer in vacuum mode and vacuum hose attached, the water in the skimmer aerates, and the air seems to be entering through the vacuum port as I witnessed a stream of fine bubbles in the water. The vacuum hose was just purchased a couple weeks ago, so hopefully it's air/watertight. There are no outward water leaks from or around the skimmer, and the stream of bubbles is not there if the hose is not connected.
Aside from the possibility of a defective hose, I think I have it narrowed down to one of these theories:
Skimmer gasket leaks under heavy vacuum, but is fine with neutral pressure
Gases disassociating from the fluid due to heavy vacuum (this seems less likely)
Am I on the right track here? I'd like to get this figured out because I can't vacuum for more than a few minutes before the whole system aerates and messes up the filtration.
Thanks in advance!
