I have intakes to my pump from a main drain and 2 skimmers. When I replaced the pump I just made adjustments to the existing plumbing to get it lined up with the new pump inlet. When needed, I struggle being able to run the pump on the main drain only and am wondering if it would be worthwhile to redo my configuration to eliminate the the two joints circled in the image attached. Is it possible that these two additional restrictions would be having an impact on the water being made available to the pump? Thank you.
