My skimmer and drains are on the same valve with a hand crank. I can have water suctioned through one or the other, or partial from both. I have always kept it right in the middle -- 1/2 drains, 1/2 skimmer. I understand the importance of having at least some water coming back from the drains in case the skimmer basket gets clogged, but what is the ideal proportion? I heard someone does about 1/3 drains, 2/3 skimmer. If I know my skimmer isn't going to get clogged, is it better to leave the drains off most of the time? What is everyone else doing?
Thank you so much! This site has been a lifesaver!
