I have a 28 foot above ground pool with a center drain. We had some very strong wind and rain over the past couple of days. I noticed that my pillow was no longer visible under my cover. I went to investigate and discovered that the water had drained to almost a foot from ground level. I am filling it back up now due to fear of the walls collapsing. I looked around the pool and notice a large damp area about a 4 foot section on the ground. I estimate i am loosing about a 1/2 gallon an hour. This area is the low point of my yard so i assume the water is draining to this location. I called the pool company but they told me it was to cold to dive. What would you do??
