What Is Water Circulation?

Water circulation is the movement of pool water through collection points, pumping and treatment equipment, and back into the pool.

How It Works

A typical route runs from a skimmer through the pump and filter to return fittings. Actual systems may include other suction points, heaters, and treatment equipment. Circulation does not guarantee every part of a pool receives equal flow.
