Closed loop or no closed loop on an irregular shape pool??????
The work has started on my remodel which includes totally new plumbing. If I want him to do so, the contractor will install a 2" closed loop with 1.5" to each inlet. It was going to be 1 skimmer and 6 inlets but will be 2 skimmers and 4 inlets. My understanding from other posts here is the closed loop would result in equal pressure at all of the inlets. But he recommends an open loop with one 2" pipe for the west side and another 2" for the east side (the 2 longs sides of an irregular shape pool). He dos not think that an equal amount of pressure to each inlet is right for my pool because one inlet needs to push the water much further than the others. Each 2" pipe would have a manual valve to adjust how much of the water goes to each. Because of the location of the skimmers and the shape of the pool, the west pipe will have 3 inlets but the east pipe will only have 1 (the 1 skimmer is on the shallow end of the east side and the other is at the deep end of the east side). So almost all of the east side and most of the south side will not have any inlets. The 4 inlets are positioned to move the water counter clockwise to the skimmers.
The closed loop certainly made sense when the plan was 1 skimmer and inlets but this does make sense with 2 skimmers and 4 inlets. The pool is surrounded on 3 sides by many large trees. So I do get a LOT of leaves in the pool which is why he suggested the 2nd skimmer. FYI, he is not charging me extra to add the 2nd skimmer and delete 2 inlets. He will do either for the same price.
Please let me know what you would do. Thank you
