I have a kidney shaped pool with the skimmer centered on the straight side and an eyeball return on either side of it. I also have two returns on the steps which are located at one end. Originally they were the whirlpool kind (connected to air pipe) but that was later disconnected and converted into regular eyeball ones. No returns on the curved side. There are two main drains in the deep end.
I've been trying to find a configuration similar to mine to determine the proper direction but haven't had any luck. I've also read conflicting info on whether to point them down or parallel to water.
