Looking to the experience of forum members on my 30 ft above ground pool liner. So living in MN, I waited until it was getting down to freezing consistently and waited as long as I could. My Pool Math note says water temp was 47 degrees when I cleaned and closed the pool in early November...just like done previous years. One night, months later, going out with the dogs, something caught my eye and didn't look right. The pool had less water in it and sunk down in the middle. Sure enough, walked around the pool and found a spot where it was all soggy and then had standing water; it had to have water coming out....the liner had a hole.
Now, as an engineer, I wondered if I was correct on how the pool froze and in the coming days I got my answer. There was about 10 inches of ice on the top and the sides froze inward about 10 inches. The liquid water in the center drained out so without support, the middle dropped. Since it was winter and freezing cold, this remaining "C" shape has held the sidewalls out in the right location all winter.
Now it is getting warm and all that ice is melting. The side where the leak is located happens to be shaded by the sidewalls of the pool from the low sun so that snow & ice has not melted yet to see what the hole or tear looks like. We have reserved ourselves to replacing the liner as we installed it in 2017 (from my build post questions here) and sounds like that is about the life of a Swimline liner.
I noticed last year I could feel a few of the post's plastic feet thru the liner. It was almost like the foam cove molding I used deteriorated. Has anybody had this issue before and how did you resolve it? I am assuming I need to replace the cove foam all the way around or is there something better to use now? I think i used Gorilla ducktape to tape the cove to the wall and the cove to the 2" foam floor.
The cause I have is guessing from yard tracks in the grass maybe moles may have migrated from the neighbors yard. After all these years, they might have found my pool 2" foam 4x8 sheets a place to hang out for the winter and chewed into my liner. Has anybody had issues with vermin and found a good way to deal with them other than the dynamite method shown in the movie Caddyshack with Bill Murray and the gopher? A friend who sets up a hockey rink says you need to kill all your lawn grubs to remove them but not sure how to do that under the pool and foam.
Suggestions or info on your experiences appreciated!
