Our PB will be starting soon, once the weather clears up. His foreman came out last week and looked the site over. He seems really good. However, one thing he mentioned seemed odd.
Our pool will be a 18' x 35' freeform lagoon shaped pool. He said for the last few years, they have started putting the skimmers (x2) AND the returns (x4) on the same side of the pool...but the returns are much deeper/lower in the water. He said it serves two purposes, it is on the house side so you don't see them much...but more importantly he said the returns are down low in the water thus causing the pool to "overturn" instead of "swirl". He said there have been studies that show this configuration better mixes your chemicals/water temps since the deeper water is moving...not just the top surface.
Anyone heard of this? He said the Main Drains don't really pull in that much water (based on some dye tests) and this method they have found to be better for circulation.
Any cause for concern? Seems to me this configuration would be easier plumbing...but is it better for circulation?
