Pool Pumps

Selecting a Pool Pump

The heart of a pool's circulation system, the pool pump pulls water from one or more suction ports (skimmers and main drain), and pushes it through the filtering, heating and sanitizing equipment, and back to the pool through the wall returns, floor returns, pressure cleaners or water features. The pool pump has the most important job on the pool equipment pad, because when the pump is not working, nothing else works either.

Which pump is right for your pool?

Unlike a pool filter, a bigger pump is not always a good thing. Unless you have been advised by a pool professional or are otherwise certain that your existing pump was undersized, it would be wise to keep the same horsepower as you have now. However, more important than matching pump horsepower is matching pump flow rates. Different pool pumps produce different flow rates, even if they are the same horsepower. Flow rates that are too high can damage your filter and piping, and result in ineffective filtration.

If the existing pump has done you well, it is easiest to replace a failed pool pump with the exact same make/model/size of pump. The height and length will also the same, which makes the plumbing job much easier. A different pump will usually require some adjustment to fit the pipes to the height of the front inlet and the length to the back discharge port. Dimensions of most pumps can be found on any specific pump’s product page, and some do match up.
