Our newly installed pool liner (done by a pool company) has an approximately 12 inch section where the liner is wavy, and isn't laying flat against the wall (think of it as up and down hills if you run your hand along it). It's like there was too much liner to fit in that amount of space. It reminds me of how drapes hang on a window and is very noticeable. The section is on our swimout/bench, so it is about a 4' x 6' curved area. Our PB said it's fixable in the spring and happened because of the temperature (it was in the high 40's--low 50's). I find this hard to believe. I have a bad feeling it wasn't made correctly. Unfortunately our pool is filled with water so it's too late to start over! Does anyone think it can be fixed?
