Have fun with family and friends in your backyard with this Bestway Power Steel pool set 56620. The pool can be set up quickly and easily. The robust 3-ply sidewalls provide superior strength and durability. The corrosion-resistant metal frame guarantees a stable and robust construction. The built-in outflow valve makes it easy to drain water by attaching the valve to a garden hose (with the included adapter). The filter cartridge pump is part of the circulation system to keep the water clean, to prevent algae, fungi and other microbial bacteria from growing in your pool. The ladder helps swimmers get in and out of the pool.
