Abstract
A skimmer filter and pumping unit for an above-ground swimming pool including portable pools in which a centrifugal pump is mounted on a base beside the pool. A cartridge-type filter unit having a cylindrical housing is supported from the base above the pump with the pump and cylindrical housing aligned along a common vertical axis. A skimmer unit is mounted on top of the filter unit and has an opening in the side adapted to open through the side of the pool adjacent the top of the pool when the base is resting on the ground. Water moves directly through the skimmer unit down through the filter into the pump, the pump dishcarge being connected back through the side of the pool below the skimmer.
