Go ahead and start site prep, NOW. The pool site should be about 12' x 15' and should be LEVEL. Not nearly level, but actually level.

Maybe 5% of Intex pools have problems. Intex will eventually honor warranties, but it's MUCH easier to return the pool during the 30-day window Amazon or Walmart have. But you need to be ready to put your pool up right away, and start using it, so any defects will show up before the 30 days are gone.
