I hope I'm not double posting, my last post doesn't appear to have gone through.
After cleaning out my pump basket, I started getting a lot of air bubbles coming out of the spa jets in my pool. The pool jets do not bubble. My spa also seems to be draining down despite the fact that I have the valves set to pull only about 25% of water from the spa, and return 50-50 to spa & pool. If I set the suction valve to 100% spa, I can see the air accumulate in the pump lid and get all frothy.
Seems like an air leak in the suction line from the spa, but why would the spa be draining down? And why only bubbles in the spa jets, and not in the pool jets? Even if I return 100% to the pool, the pool jets don't bubble. I'm a thoroughly confused new pool owner.
Here are some pictures. First image shows the amount of bubbles and how far the spa is draining. Second image shows where my valves are set that resulted in the drain down of the spa. Third image is just an overall of my equipment.
