This complete above-ground pool set is easy to set up and thanks to the rust-resistant steel frame and heavy-duty PVC and polyester 3-ply side walls, you know it'll last for years to come. As easy as it is to set up, taking it down at the end of the season is just as easy. You can rest easy knowing your lawn isn't in danger. The drain valve attaches to a garden hose so you can drain the water away from the pool. Hook the surface skimmer over the wall of the pool, right near its suction inlet. Right after it attaches to the filter pump it will start cleaning away. It has an adjustable mounting bracket so it can moved to be match the pool surface's water line. Empty the skimmer when it gets full and clean as needed. The skimmer is made of corrosion-proof material, so it can handle even the toughest pool chemicals.
