First post and i'd like to say that pool school and the forum has helped me so much with my first pool! I just bought a new home with a pool, which due to Hurricane Sandy, has been exposed for about 7 months. I spent the last week shocking and cleaning the debris. I noticed that the first step into the pool seems to have a lifted lining. I did some research and found how to fix it when the vinyl comes apart from the coping, but I can't find any information about my issue. With my hand I can easily press down into this diagonal section of the liner. I don't think it's supposed to be this way. In fact, it seems like it would be difficult to get in and out of the pool without this first step. I'm also afraid of any damage that can be caused if someone steps on this part of the lining.
The image below is my illustration of what's going on. I'll take a photo tonight.
Is there any way to fix this? Thanks!
