Setting up a pool on unlevel ground is not recommended as it can damage the pool or yard and put the safety of those using it at risk. If a pool isn't level, the water's weight won't distribute evenly, putting excessive pressure on certain parts. This can cause the pool liner to tear or the walls to collapse, leading to water damage, expensive repairs, or potential injury to swimmers. It is more cost-effective to level the ground correctly before installation rather than waiting to address serious structural issues later.

The steps to fill a swimming pool will depend on your local building codes. However, it starts with draining the pool of all water using a submersible pump. Then your pro will lift the pool shell from the ground or break it into pieces for individual removal. The next step is filling the cavity with dirt and gravel and topping it with topsoil. Once a structural engineer deems the site safe, landscaping can start.

It's not a good idea to drain an aboveground pool into your yard since the pool water's chemicals can harm your plants and the surrounding ecosystem. Instead, it's best to drain the pool into an appropriate sewer so it can be processed at a water treatment plant. You might also be able to drain it into your storm drain, depending on your region. Check with your city to learn about any relevant regulations.

A pool chiller will take anywhere from 12 to 14 hours to lower your pool's temperature by 1 to 15 degrees. Most people tend to run their coolers overnight, but larger pools in warm climates take longer to cool. Choosing a chiller with the right capacity can help speed up the process.
