I have a 16 x 32 in ground vinyl pool with one return in the shallow end. How should the eye ball be pointed? Should I be getting some surface movement - in other words point the eyeball slightly up towards the surface of the water in the shallow end - or since I only have one - should it be pointed toward the middle of the pool (in terms of depth) and towards the deep end?
Should my pool really have two returns? I do have another eyeball fitting in the deeper end but it only has the trim ring on it. It's covered by the liner and it not returning any water - obviously. It also looks like I have a second return pipe sticking up out of the ground near the filter but nothing is attached to it.
Just an FYI - the pool does have a bottom drain.
