I'm new here, and new to Intex pools. Hope I'm in the right thread...any way, my question is, my 13 yr old daughter and I were in our 18'x48" Intex metal frame pool yesterday and a couple of the legs made a popping sound. It was kind of loud, almost like a rock had hit my vinyl fence kind of sound. Just wondering if that is normal within the first few swims. I have (I think 12x12) blocks under each of the 18 legs. So I'm thinking maybe they swung out a little. They all seem to be pretty level still, but maybe 2 might be off a hair. Btw, I hate this pool lol, it's been a head ache since I've had to fill it twice now, and still don't feel comfortable with it. Any help or knowledge on this would be appreciated. Thanks in advance!!
