Just make sure your in there when she cuts loose! lol. Then start regrouping for next year! I did the jack method the first year I tried to, "throw up the pool real quick!" Only had a couple of near misses. Not something I'd send my girlfriend out to do, well... by herself anyways! BUT, I am familiar with heavy rigging and looking for caution points. That said, if you don't already even have a floor jack, Id probably look for a different route altogether. You may end up frustration ahead if you just drained it and started over. And I know that sucks and no one wants to hear that. Like Casey said sometime you'll have to cut into the high side of your slope there and figure your depth and diameter of your pool, then level it off so low side of slope is still on mother natures own compacted dirt. I would definitely NOT use a bottle jack, they have too small of a footprint and too little of a lifting head. A floor jack will dig its wheels into the earth as it goes under load and is somewhat stable. Also a floor jack has a lot bigger jack head in the form of a plate to get 2x4 positioned right. The top of the 2x4 sits pretty good once its nestled into the T just right. I found the weak point to be the bottom of the 2x4 sitting on the jack plate. I kind of learned as I went and yielded caution when things didn't seem right. Also youll have to be careful not to cut your pool with tools working in tight spaces. But cant get over the idea of being in there when she lets loose. Sounds like a cool party
EDIT: This was meant for the really bad pool in the pictures. Guess that's what happens when someone uses sand to level the ground, which I remember reading somewhere here that it was not a very good idea cause it will all push out or wash away. Unless it sat in a hole or had a tall sand ring around the pool. The 1" probably even 1.5" difference is probably just bad for asthetics and will be fine. Being the low spot that's where all over flow or waves will continue spilling out onto same spots possibly causing more more rapid settling.
