We bought a roller and compacted soil
You did nothing to compact the soil with a roller. Seriously, you compacted maybe the top 1/4" of soil if you were luck, and almost definitely not to its maximum dry density.
I know the safest recommendation is to have it level within 1" but I also know there is a safe maximum inch out of level.. I just wanted to get a feel for real users and real experiences with a level top rail and straight legs and no leaning how safe I really am at 2" unlevel between opposite ends?
1" is what is recommended because 1" is considered safe. An above ground pool, especially an Intex type pool such as yours, is nothing more than a giant vinyl bag full of (heavy) water that is deriving all of its structural support from the integrity of the top ring and posts. It relies on all of the horizonal forces being in balance. Every bit it is out of level leads to greater unbalanced forces.
Again I believe these pools are built to withstand more than Google searches would lead you to believe. If they weren't durable they wouldn't sell them, this is not a wonky setup with legs all disheveled and the liner angled in different positions, it is level in many different ways. I believe some shifts in soft soil bottom and weight of pool caused an unlevel appearance that is valid but not necessarily "unsafe" ... I'm definitely not an expert and do have concerns but I'm not ignorant either so as I internally analyze I thought I'd put feelers out and make connections with other personal experiences.
I think you are looking at the facts, and you know they are the facts, but you don't want own up to the harsh reality that your pool likely needs to be re-done. I get it, it sucks. It is a lot of wasted work and money. But the fact is, the limits recommended by the manufacturer are there for a reason. Of course there is a factor of safety built into those limits. But the FS is there for a reason as well. Somebody leaning over the rail to try and reach a dropped float while someone else does a cannonball and all of a sudden you pool has turned into a giant, temporary, slip and slide.
Thank you for your reply. I am not using the tiles to measure I'm just saying they make the unevenness stand out more and make it look more distorted. I have measured the water surface to the top of the rail all around the pool and that's where I got the 2-in difference. I believe despite the excavating, leveling, and compacting we did The rains of course loosened up the soil and we installed on mud causing shifts in the soil of leading to the unlevel outcome. I used a level between every section and they are all within range. I used a string level across pool both ways and it shows level ... Not to mention after a couple of inches of water were in the pool and I was smoothing out the liner I came upon a rock that would not go back down into the ground so it took three .. two holding up the liner and me shimmying underneath it to remove the rock, successfully, but again this caused the soil to shift and that is "the deep end". You are right I am not going to find a definitive answer which is hard for my analytical brain. My thorough assessment and involvement in everything about this installation tells me it's safe for the season and I fully intend to make corrections before winterizing it.
I guess I'm just disappointed it's not perfect.
I will also note that the 2-in difference or high side is only on one section consisting of 7 out of 24 legs. The rest of the pool is within 1" or less level. If that makes sense...
Based on everything I've shared i would assume the liner is not sitting quite right but it looks uniform all the way around and as I stated no bulging or leaning.
Forget looing at the liner. Go around the pool and measure from the water line to the bottom of the top rail. Those measurements should all be withing 2 inches. It really does not matter if one leg is 2" low and all of the others are dead on, or if half the pool is lower than the other. Or even if somehow they are all in the same plane, but still 2" off of the water line. The liner is not a structural element, per se. The legs and rails are. The legs need to be plumb, and the rail level.
It is also recommended that you do not install a pool on any sort of fill dirt. You dig down to level, and that is all. If you have torn up the ground, you need to dig down more. Compacting fill is not as simple as "packing it real good". Adding water to help it pack is not a thing (well, it is, but it has to be the proper amount of water as determined by testing). A garden roller provides next to no compaction. Hand compactors really don' either. A BIG vibratory plate can be used, but it has to be used correctly, with the proper moisture content. Most people do not have the ability to A) Determine optimum moisture content and the acceptable deviation. B) What the water content of the soil is C) How much of the maximum dry density you have compacted the soil to.
