First I want to thank all of the members in the forum for sharing their knowledge and experience with pools, I have found the information very helpful in our pool project which I will post later today.
My question is this: should the skimmers use 2" PVC On the entire run?
We are building a 41' x 21' free form gunite pool with an 18" raised spa 3'6" to 8'6" deep. The pool equipment is 51' from one skimmer and about 21' from the other skimmer. The plumbers used 2" PVC for 75% of the run and used 1.5" PVC on 25% of run (in last part of run to skimmer) for the skimmer furthest away from equipment. The closer skimmer has all 2" PVC.
I asked my pool builder what size PCV was used to skimmers and he said 2". When I asked him about the 1.5" PVC in the run to the skimmer he said it was done intentionally so that the skimmer furthest away from the equipment will have better suction and that of equal amount to the other skimmer closer to the equipment.
Does this sound right?
