Thanks for the posts guys. Unfortunately, I'm not going to be able to look into this for a few days. When I get the time I'll get the winter cover off so I can evaluate the damage to the liner. I'm not sure I'm up to doing a liner install myself with a bottom drain, light and steps. The other concern I would have is the vermiculite floor. I've read that it would need to be shaped up before the new liner is installed.
