Hi all. New pool owner here and new to the forum also. I've searched other posts for "bubbles from jets" but none seem to fit my situation.

After cleaning my filter cartridge I noticed that bubbles are coming from my return jets (but only 2 of the 5). I can't swear it wasn't doing this before but don't remember seeing bubbles previously.

The 2 jets are at the shallow end and sit close to what looks like a skimmer cover. But if you remove the lid there is only an open pvc pipe. There is also gurgling coming from the pipe.

The air must be coming from here because if I seal the pipe with my hand the bubbles and the gurgling stop. What exactly is this ummm....intake? And is it a concern that I am seeing these bubbles?

Thanks,
Brett
