MAC.DBLUES: I have not counted the number of legs that are not perpendicular to the ground. Off the top of my head, I'd guess maybe 10% of them, spread pretty evenly around all sides of the pool. When filled, one side was about 2.5 inches higher than the other side, so I simply took a spade and scooped some dirt/sand out from under the legs on the high side, so now it's only 1 inch off level. Making that change did not affect the angle at which any of those legs stood. The ones that are splayed were probably splayed when I started to add water. I just didn't notice them being splayed.
I don't know physics too well, but on one hand I can see how having legs splayed would be a good thing in that it pushes the circular metal frame inwards. On the other hand, I can see how having vertical legs perpendicular to the ground would provide support to the side of the liner, which seems to be the point of the white band around it.
I'd hate to think of the damage that 48 tons (11 foot radius squared x 3.14 x 4 foot depth x 7.48 gallons x 8.345 pounds divided by 2000) of rapidly moving water would cause to my house and fence if it were to fail catastrophically.
I called Intex customer support, but the foreigner I got on the phone spoke English so poorly that she failed to understand what I was describing, no matter how many different ways I described it.
