Hi, I have two questions I hope to get help with 
1. When I divert all the suction from skimmer to main drain, I get consistent bubbling in my returns. When I switch it to 25/75 (skimmer/main), i don't get bubbles. Does this mean air is getting introduced into the plumbing between the main drain and the pump? How big of an issue is this? I remember it being an issue last year too. How do I fix this? We haven't noticed any leaking or any change in pool level.
2. We just installed this new VS pump (Pureline 2626 / 2606) and all went well, but I've noticed the pump basket is not always full of water when the filter pressure is about 5 higher than the clean pressure. Is this normal? Our starting pressure went is 10. So now, at 15PSI, I've been backwashing and that's when I noticed the pump basket wasn't full when the pump is on at normal speed.
Thanks so much, Patty
