I have a 15k gallon (or so) fiberglass in ground pool. Something I have noticed over the past few years is the bulging inward of two of the sides (across from each other). The pool is about 15 years old (I moved in 2 years ago) I am not sure how long its been like this. Its pretty noticeable and I am curious if this is something that happens and if I should be worried of a catastrophic disaster.
Thank you!
