Bestway Pools Practically Install Themselves! Spread out the 13 ft round pool on a level area with good drainage, and inflate the top ring. Drop in a hose and the pool walls will raise themselves, as the water level rises. Connect the FlowClear cartridge filter pump and hoses to the pool inlet/outlet ports. Plug-in the pump (included) to a nearby outlet to begin circulation and filtration. Add a few chlorine tablets to a floating chlorinator to begin sanitizing the water and you are ready to swim! Plenty of time leftover to take a look at our relaxing pool floats and loungers, and begin your new pool lifestyle!
