Choosing an Above Ground Pool Pump
An above ground pool pump is built for a different job than an in-ground pump. It sits beside the pool at or below the water line, so water flows to it by gravity, and most models run on 115V with a cord that plugs into a GFCI-protected outlet — no hardwiring needed. That makes replacement a simple, same-day job for most pool owners.
Size matters more than horsepower. Most above ground pools are well served by a 1 to 1.5 HP pump, and the pump should be matched to your filter: a pump that pushes more water than the filter is rated for wears the filter out faster without cleaning the water any better. Check the flow rating on your filter's label before you order.
