Every above ground pool has a surface skimmer, whether it is over the wall or through the wall. The skimmer can only take the top 6-8″ of water from the top of the pool and send it through the filter and back into the pool.
The purpose of the floor drain is to improve filtration and circulation by drawing the water in the pool from the floor drains as well as the skimmer. Now there is filtration from two spots instead of just one. The result is a cleaner, clearer pool and less vacuuming. Dirt and debris can be brushed to the bottom drain where it will be picked up and sent to the filtration system. Now that saves you time and work!
