I have 27' AGP that came with the house when I bought it less than 2 years ago. It always had these liner wrinkles on the bottom, but I never had issues with it. Today I noticed something scary bulging in those wrinkles. Large hard lumps that look like rocks or roots. Wrinkles also got much higher and also hard. It looks like a tree root system or miniature mountain range I didn't see those few week ago when I was vacuuming...
I imagine two possibilities. One it's tree roots (I do have large trees around pool) buckling floor. Second is ground is shifting and rocks are now protruding. I actually don't know what's at the bottom. Is it aluminum floor? Or just ground and some kind of padding?
I was just about to close pool for the season (I live in upstate NY) when I noticed these... What should I do? Drain and inspect? Leave it until Spring? I'm afraid if I leave it liner might just break at the bulge and I have catastrophic flooding (don't want my basement to be flooded).
Is pool done for?
Additionally we did have some heavy rain fall a week ago and pool filled up, but this whole week there wasn't any rain at all...bulge02.jpg
