I have 3 skimmers and 3 returns. The motor is a 1.65HP various speed and placed on one side, 10 feet away from the pool. When I run it @highest speed, it is pretty obvious that the closest skimmer and return work best, and the farthest works worst. When I run @lower speed, obvious there is even no water flow returned from farthest and very small from the middle ones.
Is it reasonable? I actually care more about the skimmers than returns, because if there are some leaves or branches on the other side of the pool, it is very hard for the farthest skimmer to catch them. Is that possible to adjust the inflow of a skimmer so that I can balance the flow among all 3 of them? Same question for the returns. but I doubt if there is any way to adjust that.
