I am about to embark on a renovation of a 36 year old Sylvan concrete kidney shaped pool. It is about 32x16 - slightly wider in the deep end. There are 2 skimmers, 2 main drains and two returns. The skimmers are being replace as well as all of the plumbing. I want to relocate the return lines as they are currently located directly underneath the skimmers ('elbow' directionals attached to returns). I am doing this for better circulation. So, where is the best place to locate the returns assuming that my skimmers will stay where they are. The skimmers are on the lobes of the kidney. Not sure how to really describe it - here it goes, if the kidney were to stand up, where the two parts touch the ground is where the skimmers are.
I am not limited to just two returns perhaps three. There is also a small extension in the shallow end that has steps. I was thinking of something to improve circulation there as it seems to have dead spots there.
Thanks for your help!
