My pool was installed less than 3 months ago. I noticed it looked off by the water line so I took a tape measure to it. About half of the pool is 4 to 4-1/4 inches from water to rail (level a bit low due to our water restrictions). The other half ranges from 3 to 6 inches from water to rail (not even sure I found the lowest and highest point but pretty close). I took pics showing the measurements to the pool store, they called installer. He said he'd come look next week and would be willing to take it down and re-level. I told him about water restrictions and he said he'd be willing to do it in the spring. What I'm wondering is should I mess with it? Is it unsafe? And if I do have it done, will the liner shrink over the days between the drain, re-level, and refill? I doubt the installer wants to pay for a new liner. I can't decide what to do. Seeing it does bug me but I'm not sure anyone else even notices it. Most concerned if it's unsafe. I don't want to be nit picking. Pool store is awesome and just gave me a whole new top for the filter (multi-valve housing) because it had a drip. Thanks for your thoughts!
