Hi,

I have recently set up an Intex 10' x20' rectangular metal frame pool with a vinyl liner on my backyard, (concrete surface) and started pooring water into it, I am almost half way and have noticed that the side walls (20') are starting to curve towards the inside of the pool so I stopped filling more water into it. I am wondering if this is normal or if this means that the concrete surface is not really leveled, which I think is the case, I am assuming the raining water needs to flow somewhere.

Should I be concerned or would you say once the water reaches the required level, it will realing the side wall frame.

Thanks

Sacto
