Ready for water in 10 minutes! Included pump and filter make it easy to maintain! These pools have the easiest assembly on the market – just inflate the damage resistant ring at the top of each pool, then fill with water. A water filtration pump with cartridge keeps your pool clean, a ground fault circuit interrupter keeps it safe, and the drain plug connects to a garden hose for water to be drained away from pool. Pools available in multiple sizes with vinyl walls. Instruction video is included. Filtration pump has a one year limited warranty. Add the durable vinyl pool cover with rope ties to help keep out debris and prevent water accumulation. Replacement filter cartridge (works with all sizes) and pool covers sold separately.
