this is a picture of my jandy valve that operates my skimmer/drain. My skimmer sucks water just fine, however the bottom drain is not. I put small floating debris next to the bottom drain and they do not get sucked in. I have played with the valve in every direction and I cannot get my skimmer to turn off or my bottom drain to suck. This is a new to me pool I just bought the home a couple months ago and installed a new pump and filter assembly. I'm not sure how to fix this or if I should just leave the skimmer to do all the work?
