If you are 2 to 3 inches out of level the pool is not going to collapse. If these pools collapsed that easily they would not sell them. You will hear many post here telling you that the sky is falling. People say things enough times and it makes it true. I wonder if anyone has ever had first hand knowledge of an Intex pool collapsing because it was 3 inches out of level. Not that you heard it from your sisters brothers cousin, actual first hand knowledge.
