I'm fairly confident this is an easy one, but my pool's eyeballs, when fully tightened, are pointed straight out. In a previous post, someone felt the location of dead algae in the pool indicated they were pointed incorrectly and should be pointed toward the center of the pool so that debris could be pushed toward the center for the skimmer to pick it up. This ended up fixing a lot of my problems.
However, in order to fix the direction of the eyeballs, I had to loosen them on the threads. When I'm trying to vacuum, I see air bubbles coming from behind the eyeballs as a result. Have a hard time believing every pool owner has to tighten their eyeballs every time they want to vacuum to seal up circulation. Any suggestions to have them point inward correctly and be tight on the threads?
