The Bestway 15' x 42" Fast Set Pool is the perfect size for families with children, providing a suitable depth for kids to splash around and play in. The above ground pool's practical size also ensures those with small backyard spaces can enjoy watery fun in the summer sun. So get out of the house and into the refreshing water with the Fast Set Pool Set. One of the best features about the compact Bestway 15'x42" Fast Set Pool is how incredibly simple it is to set up. The Fast Set Swimming Pool can be ready in under an hour using little more than an air pump (not included). Simply inflate the top ring and fill the base with water. As the pool fills up, its outer wall, which is made by sandwiching polyester mesh between tough, heavy gauge PVC layers, spreads out and rises. Once the water has reached its maximum capacity you're free to clamber in, splash around and cool down. Get years of use out of the Fast Set Pool Set thanks to its heavy-duty PVC and polyester 3-ply side walls. The liner is supported by an inflatable top ring. A flow control drain valve offers easy draining. The pool comes with a free DVD detailing pool set-up and maintenance. The Fast Set Pool Set comes with 530 gallon Flowclear filter pump and filter cartridge and heavy-duty repair patch.
