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.

The time it takes for a pool heater to heat a pool can range from eight to 48 hours, with an average of about 12 hours for the initial heating. For a more specific example, an average-sized 15,000-gallon pool may take six to 10 hours to heat up by 10 degrees. The exact duration depends on several factors, including the pool's size, the type and size of the heater, the starting water temperature, and the outside air temperature. It may take some trial and error to determine the precise time your specific pool takes to reach a desired temperature.

If you have a smooth, already bonded concrete surface, painting a concrete pool deck can be a great way to brighten up the area and add longevity. If the surface has another covering or a different type of paint has been used previously, you won’t be able to paint it without removing the existing coating. Wooden decks benefit from painting as it helps to keep them watertight. Quality pool deck paints also help make the surface less slippery and less likely to gather mold and mildew or prematurely crack.

There are some companies that offer acid washes that do not require pool draining. However, the process can take several days and requires a bit more elbow grease to scrub the pool surface compared to draining it entirely. Since your pool surface and age are both a factor, work with a professional to choose the best method.
