The 13′ x 33″ Fast Set Pool Set by Bestway is a great family swimming pool. It sets up in only a matter of minutes on a flat surface as only the top ring needs inflating; the body of the pool has a liner that lifts when you fill the pool with water. The set includes a 530 gallon filter pump and filter cartridge to keep the water fresh and clean. It also comes with a flow control drain valve, allowing it to be drained quickly at the end of the season. The Fast Set Pool is constructed of tough TriTech material, making it extremely durable and guarantees to keep the family swimming for years to come!
