Fill a large bucket with pool water, and place it on the steps of the pool. Leave a few inches between the top of the bucket and the pool. Leave the bucket for several days, and inspect the water level in the bucket and your pool. If there's a difference in the water levels, you have a leak.
Fill the pool to its original level, and mark the level with a piece of duct tape. Turn on your filter system, and leave it running for 24 hours. Measure the water loss, and record the results.
Switch off the filter system, and refill the swimming pool to its original level. Wait 24 hours, measure the water loss, and record the results. Do both tests during the same time of day to ensure the most accurate results.

Losing more water with the filter system turned off indicates a problem with the vacuum components of the plumbing, usually ahead of the impeller. Matching water loss in both cases indicates structural rather than plumbing problems.
