I am not getting the suction power from my skimmer when I turn my Jandy valve to vacuum mode like I did last year. The water pressure starts to build for maybe 10 seconds, then it's as if I turned the valve back to the middle main filter drains. Water in the pump basket falls to almost nothing, pressure guage on the filter drops to zero, I have to open the relief valve to let the air out of the filter tank.
There were lots of leaves in the pool when I opened this summer, and I vacuumed them out through the skimmer and the vacuum hose was constantly getting clogged where it empties into the skimmer. Could the skimmer line be clogged w/debris? Sometimes squirrels bring pecans to the pool to do whatever they do w/pecans in a pool (party?). I did use my large shop vac to blow through the line a couple of times.
