At the beginning of the season my above ground pool (round 18') was emptied and cleaned and then filled. I understand now that emptying can possible damage the liner. We had a great swimming season and took good care of the pool thanks to the help of the forum. On Sunday night I noticed that the water was down past the skimmer, and I assumed one of the plumbing connections came loose. When I went back out Tuesday evening the whole entire pool was empty. I was shocked. I didn't notice any major holes in the liner, but I dont understand how it could empty that fast if it was a small hole.
I need to go out tonight and inspect it carefully. The liner also looks really loose but I don't know if that is just normal when the pool is empty.
Can someone help walk me through what I need to do? Is it possible to patch the liner? If not do I need to replace the liner? How much would that potentially cost? It's about time to close the pool down anyways, how much do I need to fill it to leave it for the winter season? Any other help or pointers I'd greatly appreciate. I can take some picture tonight if that would help.
