While you should avoid draining an above ground pool on a regular basis, it may be necessary if you are experiencing common signs of major pool problems. When you fully drain your pool, do so slowly with the proper equipment and always avoid draining on a very hot day. In many cases, the pool liner and equipment depend on the cooling effect of the water.

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.

Draining a pool with a garden hose can take between eight and 14 hours depending on the depth of your pool and whether you use a sump pump. Be sure to stay close to the pool during this time to ensure the structure of your pool remains unharmed and that the water drains properly.

The cost to repair a swimming pool varies widely, with an average cost around $700. The total expense can range from as little as $10 for simple DIY fixes to over $20,000 for extensive overhauls. Key factors influencing the cost include the type of pool (in-ground vs. above-ground), its size, and the specific repairs needed. For above-ground pools, repairs typically cost between $100 and $700. For in-ground pools, costs are higher, generally ranging from $350 to $2,700. Common repairs include patching liners, fixing plumbing or electrical lines, and repairing equipment like pumps and filters. More complex issues, such as fixing a cracked beam, can cost $6,000 or more, while major projects like resurfacing a concrete pool can cost between $10,000 and $20,000.
