A new liner is going to be installed today. Yesterday, after the pool was drained, I noticed that there were several cracks in the steps. They appear as nail pops in new drywall, as if something from the back side was pushing into the steps causing a crack. There at least 20 of these. We are replacing the liner because we kept having to put water in it last year, and it is bleached out. Could it be possible these cracks are the problem?
I have attached a photo of the cracks, as well as the pool drained. I also attached a PDF of the cracks circled, as it is hard to see them in the photo.
The pool liner, 10 years old, is completely bleached out. I would really like to minimize this happening again, so any advise is appreciated. I am currently attending Pool School.
