Hi. I am hoping someone may have some knowledge regarding an issue I have discovered after buying a used pool. While I was taking it apart I noticed that the sidewall was bent out over the bottom rail in several spots. I didn't notice this before buying it because the bends are located 2" to 3" inches from the bottom of the sidewall and this area was covered with landscaping rocks. The pool is about 7 years old and has no rust and otherwise looks in good shape. Is pool ok to continue installing or is this a bad sign and should no longer be used? Thank you
