SKIMMERS: BUYER’S GUIDE & FAQ

Most pools — above ground and inground — have a built-in skimmer system connected to the top of the wall, in some cases larger pools may have several. These systems have rectangular openings that suck in water and debris while the pump is running.

Water is pulled out of the skimmer to the attached pump and filter to be cleaned and sanitized before being sent back into the pool through the return jet. Any debris is caught by the basket is held there until you manually dump out any leaves, bugs and anything else it has accumulated.

When the pump is not running, the weir door keeps the debris trapped in the basket. This flap closes when the pump is turned off while remaining open while the filter is running to allow debris to pass.

The lid closes off the top of the skimmer. This prevents any additional debris from entering the skimmer and stops animals and others from accidentally entering the skimmer. You’ll open the lid to gain access to the inside of the skimmer, where you’ll be able to inspect it and get the basket to empty it. [Shop All Skimmers]

To pick the right skimmer for your pool, you’ll need to consider a few things. First, is your pool inground or above ground?

For above ground pools, the most important thing is picking the right size. If you’re choosing a replacement skimmer the easiest option would be to order the same skimmer model to ensure the perfect fit. If that’s not possible, you’ll want to pick a skimmer the exact same size or slightly bigger. Since a skimmer system involves a hole cut into your wall, you can’t choose a smaller skimmer.

For inground pools, you’ll want to consider the dimensions, but you’ll also need to consider the surface of your pool. If you have a vinyl or fiberglass pool, you’ll require a rubber gasket to form a seal between your pool’s surface and the faceplate. This isn’t required for gunite surface pool.

When looking at the dimensions, you’ll be looking at the mouth and the depth of the skimmer, also known as the length of the throat. You’ll want to ensure that the skimmer you purchase has a long enough channel between the skimmer mouth and the portion of the skimmer that houses the basket.

For both types of pools, you’ll want to consider the pipe size. Mismatched sizing will affect the flow. You’ll also need to consider your state’s requirements. Several states require a dual pipe to reduce the suction power of the skimmer and drain.

Finally, you’ll want to ask yourself how many skimmers you need. Small pools only require one, but larger pools may require multiple skimmers to proper circulate and collect debris. [Shop All Skimmers]
