One of the advantages of above ground pools is that the pumps and filters are sold as one unit. These pump/filter systems are usually attached to a single base and are much more economical than an individual pump and filter. Here we'll cover the basics of both pumps and filters for above ground pools.

Step by Step


Step 1

Sizing above ground pool pumps is much simpler than their inground counterparts. Above ground pool pumps are generally below the waterline thereby gravity fed, with minimal plumbing between it and its suction ports. The simplicity the pool’s plumbing allows you to size the pump by pool size alone (most times.)

Step 2

Round Pools: The chart shows the normal manufacturer pump sizing recommendations for pool sizes. The horsepower overlaps on the “tweener” sized pools 15’ is a small to medium, and 27’ is medium to large.

  • ¾ Horsepower: 8’ to 15’ Round
  • 1 Horsepower: 15’ to 24’ Round
  • 1-1/2 Horsepower: 24’ to 36’ Round

Step 3

Oval Pools: Similar to the round pools, the horsepower recommendations overlap for some models. If your pool falls in one of these overlap areas, then consider how much swimmer traffic you expect. Light to moderately used pools, choose the lower HP, for higher swimmer loads, choose the step up.

  • ¾ Horsepower: 12’ X 17’ to 12’ X 24’
  • 1 Horsepower: 12’ X 24’ to 15’ X 27’
  • 1-1/2 Horsepower: 15’ X 27’ to 18’ X 33’
