Why can't most slides be used with an aboveground pool? If it requires 4 feet of water, why does it matter whether the pool is inground or aboveground? Is it because the force of the person entering the pool on a big slide would hurt the sides of an aboveground?
Because frankly, if I was going to hit the bottom of a pool coming off a slide, I'd rather hit the soft bottom of an aboveground than the cement of an inground. Or maybe the force of someone hitting the bottom would hurt the liner on the bottom?
