Nothing like having a new liner split at a seam after less than two weeks. Happened to me. Woke up on "Mother's Day" in 2003 (wife and kid were visiting her mom) to the sound of a waterfall...but I had no water effects in my new pool--other than the split seam in the liner! The new liner (under warranty) was the ugliest install, ever. Wrinkles everywhere, and, at night with the lights on, you can see the installers' bootprints in the sand at the bottom. Naturally THAT liner has now lasted 11 seasons! (where's the facepalm smiley when I need it?)
