Hello forum, glad to be here. I attached a pic of the old liner from the pool we disassembled and brought home. It's an 18'x48" steel side about 7 yrs old. But it was free so we grabbed it up. We started on ground prep about 12 hrs ago. My biggest question is why does it say 46-1/2" on the liner? I haven't been able to find anything online that matches this with new liners. They're all 48" to 54" or something along those lines. Also, have not been able to find any info on the numbers to the left. Was hoping to reuse this liner but it became obvious that it wasn't going to happen when it started to crumble in my fingers. I've been researching how to properly reinstall this pool and I've found a lot of answers but I'm sure I'll have more so any other insight is appreciated. Planning a good sized deck too, and possibly a slide so we'll see how that goes. I'll be sure and get pics of progress. Thanks!
