Circulation from the Inside

Return inlets placed nearer to the top of the pool help push dirt and debris toward the skimmer. But lower inlets have many benefits as well, including better heat and chemical distribution, and more efficient turnovers.

Simple RectangleWhen placing return inlets on virtually any pool or spa, the goal is to move the water completely around the vessel. For a smaller rectangular pool, the job is easily done with at least two well-placed returns and two skimmers.  Medium- and larger-sized rectangles will need more returns and skimmers.

Complex CurvesFreeform and complex shapes often require more return inlets than their simpler counterparts. Jets should be placed to ensure water moves into coves and radiuses, where it could easily get stuck and stagnate. Returns located near benches, swim-outs and other such features also help keep those areas clean.
