Drain Kit A They come with a centerThis drain kit includes a vertical filter and foam float and drain fitting. It is included with all of our covers but the easy dome. It will work on any above ground pool cover. Simply drain the water level below your skimmer. As the rain water lands on the cover, it will pass through the filter and into the pool where it will over flow out through the bottom of the skimmer and onto the ground.
