With my new WFE-3 up and running, I need to approach the proper orientation of my return 3 1" return eyeball outlets. I'm getting (as near as I can tell) excellent flow from all, based on the amount of movement from the "far end" outlet. My pool is rectangular 16 x 34 and all of the return outlets are down one of the long sides. The skimmer is located in the short wall corner on the opposite side from the returns.
The first return (#1) is about 6 feet down the wall from the deep end. The second (#2) is 12 feet from the shallow end and the last (#3) is 5 feet from the shallow end corner by the steps.
After doing some searching at this site and observing the surface movement, here is my initial plan.
#1 - direct it straight out from the wall to promote deep end mixing
#2 and #3 - direct to optimize surface movement toward the deep end skimmer
One thing I have noticed is some new "blind spots" where the Kreepy is missing. I think this may be due to the new interference from the surface movement against the portion of the suction hose that is floating. I figure another weight or two might submerge the line enough to minimize this effect.
Any thoughts or suggestions are very welcome. I can post pics if that would be helpful.
