We have something very similar that when opened allows for air to come into the return jets. I have been using it to allow the pH to rise a bit. Only need to open a little to allow air to be drawn in.
Yea I was thinking that but it doesn’t look like any air is added that I can notice at least. Maybe it’s plugged inside.

Hmmm...
When mine is screwed all the way down the air stops. I can unscrew it just a bit for a little air or a lot for a lot of air. I actually took it all the way out this season in the search for hidden algae. Thankfully I didn’t find any!! But like you I did find water. Just cleaned down inside with a bottle cleaner.

Reading others posts...got me to thinking...maybe try to flush it out with water from a hose pipe. Thinking if there is any debris in there it might get flushed out by the pressure. Best of luck!
That's an air vent as there is a hole in the thread assembly to allow adjustment. Probably plugged up try flushing it out you can pour liquid chlorine diluted then a hose after a few min. Is it online with any return fittings
