I have an above ground pool. I winterized and installed the cover and in the past few weeks the water level has been dropping. There must be a leak (I am not sure how old the liner is, but it could be close to 20 years old). I thought that I would wait until spring to replace the liner, but today the cover fell in. The water level is so low that the rain water collecting in the cover pulled it into the pool. I am not sure what to do for the winter (I live in Michigan), should I leave it uncovered for the winter, get a new liner now, perhaps there is another creative solution that a more seasoned pool veteran may be able to offer. Thank you in advance for any help!!
