Pool vac is not moving, no obstructions. Checked all hoses and connections. Was able to take the hose out of the "wall" where it attaches (sorry I don't the correct terminology) and noticed that the suction in the actual wall is very low, barely noticeable. I cleaned the filter, all baskets, everything looks fine. Water level is normal. The 'in-deck' suction is better than the 'in pool' suction. I have a variable sped pump and increased the sped, still not moving whereas before the pool cleaner would try and crawl out of the pool. Any ideas on how to proceed or what is my next step?
