I’m backfilling my pool walls tomorrow and will finish up the plumbing shortly after. As of now I just have 1.5” pvc stubs where the returns come through the walls. I am wanting to get opinions about my proposed layout, primarily on the topic of using 1 2” pipe to supply 2 returns and branching them into 1.5” lines as they enter the pool walls. Is this a good idea, of am I better off just running each return with it’s own 1.5” line? Pool is 16x32 with 5.5’ deep end and 1-3’ shallow end. Here is a rough sketch of what I’m thinking. Above the pipes will be 3/4” gravel, ca6, and 3/4” porcelain pavers, so any re-work won’t be nearly as bad as if it were concrete.
