Hi All - we opened our pool this season to notice what looks like a very low spot along one section of wall. The picture below shows about a 2" difference in how much of the liner appears to be below the water line. I measured the depth of water at the low side and the high side, and they are both the same, so it doesn't appear that the pool floor has dipped at all. I thought the liner might be sagging or coming out of the channel, but it appears to be fine. My next step was to look at the posts to see if one may be sinking a bit, but checking it with a laser level, all the post tops are within 1/4". I'm out of ideas...Can anyone figure what is happening? Even if everything is fine, it just *looks* bad!
