Pool Not Exactly Level

[webfeet]

I see that no one has replied to your question. Perhaps you could contact the manufacturer. That is what we did, when we realized our new IG vinyl was a little out of level. Best of luck. Webfeet

I would have to say go with your instinct on this one, I have seen a few ag installs that are questionable, and eventually, an off level installation will fail... it is just a matter of time, and physics.
I would very quickly act on this, before it gets worse, damages the pool, your property, or God forbid, injure someone.

1" is definitely acceptable, however, for your peace of mind and because of what you allready mentioned above, talk to the pool store / builder, put it in writing so you can have something to go back on and then wait it out over the winter, frost will do your final settling and you will be able to make your decision come spring time.
I don't think you have much of anything to worry about, it doesn't sound like they built it up much on the low end.
I built an entire 1.5 foot high pad for my pool using fill because of potential flooding issues where my pool sits, however, I let that settle over the winter before I prepped it for the pool - makes a difference.
