My pool was part of a house purchase and we didn't build it. It seems obvious that someone decided to convert a return into a pressure cleaner connection along the way. There are three returns and a water slide feed; the booster pump is connected to the single wall return (midway down the wall opposite the skimmer), the two stair returns share a single 1.5" pipe from the pad, and the stairs use a small 3/4"(?) pipe that is T-d off the stair returns at the pad.
Due to this and the Polaris 1" tube that feeds the pressure cleaner return the flow from the side return is weaker than I would like. Additionally the stair returns are placed opposite one another on sides that parallel the long sides of the pool. Due to the design of the eyeballs - the range of directionality is limited to about 120 degrees rather than 180 - so the two returns currently either form two legs of a triangle or an X depending on my mood. Neither flow pattern is ideal for water circulation nor for skimmer use.
I do have a main drain and a skimmer and both are in use which I think helps with water circulation in this case.
What I was wondering was if these types of return fittings might help if I put them on the stairs:
If not is there another way to improve circulation from the stairs?
