I don't know what you call them other than jets. There are four around the pool and they have stuff growing in them. I have never seen water come out of them. I tried adjusting the levers with no positive results.
I have a lever that turns on the spa jets, one that turns on the water feature and one that I think switches between the bottom drain and the skimmers. When I turn that last one the filter pressure starts to rise.

Sorry false alarm. The lever that works the water feature also works the jets depending on where you put it. This will be my first summer with the pool. Still trying to figure it all out.
