Just set up the pool on what I thought was level ground. Well after filling it about 75% full i noticed it starting to bulge on one side and the water difference from end to end is about 2". The side its bulging on is leaning hard on one leg. I cant get my finger between the leg and the liner. It seems sturdy but still not sure about it. Is the liner suppose to lean hard on a leg? Did'nt know since its only leaning on one and its only off 2" if I should worry about draining it or not.
