Install Above Ground Pools FAQs, answered by experts

With a regular pool, the water is contained by visible walls that are higher than the water level. An infinity pool has one or more walls that are right at the waterline so they're not truly visible. For an invisible look, the lower wall is often made of glass or clear acrylic. The water laps over the lower edge and into a catch basin below where it gets pumped back into the pool.

The formula you’ll use to measure your pool will differ based on the shape of your pool. For a rectangular pool, you’ll use the following formula to find the size in gallons: length x width x depth x 7.5. If the depth changes from one end of your pool to the other, take the average by finding the depth at the deepest and most shallow points and dividing that number by two. Circular and oval pools require different, more complicated formulas, which can be found in this article.

When you’re winterizing your pool, you need to drain some of the water to prevent cracking and warping from ice. Nonetheless, you should never drain all of the water. Ideally, you’ll lower the water level to anywhere from four to six inches below the skimmer. This will protect the structural integrity of the walls, help prevent your pool liner from warping, and reduce damage from debris.

Many providers include essential accessories like ladders and skimmers. Confirm details before starting the project.

While some water loss from splashing and evaporation is normal, a rapid or excessive drop in the water level may indicate a leak. Other signs of a pool leak include unexplained soft or wet spots in the yard, cracks in the pool structure or falling tiles, higher-than-normal water bills, persistent algae growth or water discoloration, and standing water around the pump, pipes, or other pool equipment.
