Been trying to nail down specifics for my pool build and wanted to get TFP's opinion on the plumbing that this PB standardly puts in:
Pool is a 18' x 32' sport pool (3.5' - 5.5' - 4.0') rectangle pool, approximately 19,000 gallons.
It will have an auto cover
Pool is roughly 30' from pool equipment
PB says he puts in 2 drains, 1 skimmer, 1 "dedicated" port for a Polaris 340 and 2 returns. He states it's all plumbed with 2" schedule 40 PVC. (side note, we are putting in a shallow "baja step" and we plan on putting in two additional returns that will act as bubblers here)
I had assumed two skimmers would be appropriate for this sized pool, but he states that they'll put one skimmer on a (and up to) 20'x32' sized pool. I also thought that you typically would balance the amount of volume in and out of the pump (so have 2 drains, 2 skimmers and then have 4 returns) - is this not correct? He also said that the drains typically aren't used (unless you're draining the pool) and that most of the water to the pump will be coming from the skimmer and the dedicated port. This just doesn't make sense to me, as I would think if you were truly trying to turn over the water in the pool that you would want multiple inputs.
I'm confused and not sure what I should be requiring for this sized pool.
Thank you for your feedback!
