I love this thread. Pool fails are honestly one of my favorite things to read up on within the interwebs, mostly because I’ve had a few disasters myself. One time we were trying to install an above ground pool kit in the backyard and didn’t realize the ground had a slight slope. Looked totally fine when it was dry, but once we filled it halfway, the water shifted and the entire liner buckled on one side. Total collapse. Water everywhere. We had lawn chairs floating across the yard like it was a flash flood. It was one of those epic pool fails that feels like it belongs in a YouTube compilation.
Since then I always triple check the base before setting up anything. I’d love to hear more pool horror stories if anyone has them, especially the ones involving DIY mistakes or kids doing cannonballs into inflatable pools that were never built to handle it.
