We are in process of extending out pool deck by 4' (concrete). There is a 1.5" PVC line, which runs horizontally from the existing slab (near the spa), then turns vertical and has 2 elbows at the top reversing the line to point towards the ground. I believe it is the air intake for the spa jets. I extended the horizontal section the required 4', and this will now go through the footer when they pour the new slab.
My question: Should this horizontal line be level? With the 4' horizontal extension, this has some play to it and is currently sagging down. I am unsure if it is sagging too low, not sure if there should be visible water in it, etc. Perhaps I am overthinking it.
My kids realized that if they cover the jets with their hands, the rest of the jets stop, and water comes out of that air vent.
In all honesty, I do not understand the physics of how air is getting into this setup to make the bubbles.
