How Many Return Lines Should A Pool Have?

From https://www.swimmingpoolsteve.com/pag... - Swimming pools need a minimum of one return line in order to function; ideally though, they have three or four return lines. But how many return lines and return jets (or return ports) a pool needs depends a lot on the size and shape of the pool. For optimal skimming effect (removal of floating debris) and diffusion of the filtered and chemically treated water returning to the swimming pool, having multiple return jets in the right locations helps to both aim the flow of water towards the skimmer mouth for debris collection and removal as well as dispersing the treated water more evenly throughout the pool. Swimming pools with unique shapes may need more consideration of the number of return lines as well as the placement of them to avoid any dead zones where debris collects from lack of water flow pushing it towards the filtration system. #SwimmingPoolSteve #poolplumbing #pooljets
