Hello, We moved into a house with a 27' above ground pool. It needs a liner. When I measure the height at the edge of wall, it is about 50". This pool had a drain in the center of the pool, which we will be removing. We've been told by the neighbors that they lost the pool water more than once in the winter when that drain, full of water froze. Anyhow, when we measured the height in the middle of the pool, it is roughly 54". So I am wondering if I need to buy a special expandable type liner, or if a regular liner would be ok.

If anyone has recommendations of specific brands, and places to buy online, I would really appreciate it too!
