Our skimmer has a plate that can pivot to restrict the flow to the pump or restrict the flow at the equalizer line. We have had the plate in a position that does not restrict either line. Have run this way for 2 seasons without any known problems. The pool is now getting refinished and would like to know if we can improve the skimmer function by using the restrictor (or not) when we get the "new" pool up and running. Thanks!
