Might. Probably won't. Can't tell for sure.

PS:
There were some comments about the safety of draining a vinyl pool. IG (inground) vinyl pools can almost never be safely drained -- you'll often loose your liner if you do. AG (above ground) pools can be drained safely, depending on size and liner type. Little ones almost always can be drained. Large ones, may not be able to be drained.

But Intex type pools can always be drained.
