I bought a intex above ground 15×36 pool with the blow up top. I set it up, everything was fine except for it being not level. I drained it and moved it and started over. Once again everything was going good. I let the pool fill for about 2 hours and when I went to check on it, big mess. The water was level but the pool was filling out not up. I'm emptying it again but needed help trying to figure out what I did. I have had about 6 of this same pool and never had this problem. Please help! Thanks in advance.
