So long as they all get cleared, it doesn't matter. It seems like alot in the thinking phase, but it makes more sense when doing it. You move this valve that way and water shoots out there. Then you move the valve or the blower to get another section.What order do you think i should do this in? Drain, Skimmer, Return?
It may take a few cracks at it (seasons) to figure out how it works best for your setup. Next year you might tweak this or that and some of it will be more efficient and you'll keep doing it that way.
