I have a 2017 Intex ultra 15x48 pool that’s been amazing. Last summer, we noticed that the top of the liner started giving people teeny tiny little slivers/rashes when they touched it with their under arms. I went to order a replacement liner from infect, and they aren’t available. I’ve seen people suggest the overlap liners, which I didn’t know existed. Where is the best place to find those? My pool doesn’t have round tubing. So I worry some of the kids wouldn’t work.
