Florida State Service and Repair Pool Contractor Practice Exam

For a residential inground swimming pool with automatic skimmers, the number of skimmers required is generally determined based on the surface area of the pool. The rule of thumb used in pool design is that one skimmer is typically sufficient for every 600 to 800 square feet of surface area.

In this case, a pool with 720 square feet of surface area falls within this guideline. Therefore, one skimmer is adequate to effectively manage the overflow and maintain proper circulation of the water, ensuring that debris is efficiently collected.

This approach helps maintain the pool's cleanliness and water quality while still adhering to standards set for residential pools. Adding more skimmers would be unnecessary for this specific size, as one can adequately handle the required flow rate needed for efficient operation.
