I live in Arizona.. my hayward runs when the pump is on. currently it's an after thought and is plugged in to the skimmer. THe pool has pop up heads on the bottom that do not work worth a darn. During the replaster I am having a decicated suction line run so it will draw through the skimmer while the hayward runs as well.

I'm not sure what to do with the pop ups in the bottom. Too expensive to run a bunch of return lines so most likely they will stay.
