Got my above ground pool winterized and covered about a month ago. I have always put a plug in the return jet and put a skimmer door/cover on so I can fill the pool to the top. I have found this makes putting the cover on easier and eliminates the sag in the cover. Have done this for years with no issues. This year I noticed that the water level had dropped. i suspected a leak by at the return or skimmer but that was not the case. I have pooled water on the ground on the opposite side of the pool. Seems like I may have a leak in the liner. I did not have one before closing so not sure what happened. I will keep an eye on it to see if the level drops more. My question is... if I do have a hole/tear in the liner, what are my options? I hate to uncover, find the leak in super cold water, but what happens if i leave it alone all winter? Will it ruin the liner? Hopefully the leak is not in the bottom as I know it wouldn't be good to have any empty pool all winter. Any help or ideas would be appreciated.
