Hi,
I have a 27 foot round above ground pool. Some of the uprights seem a little bit crooked to me. A couple seem to be leaning inwards toward the pool, and one seems like it's leaning a bit sideways. This is something that you only see if you stare at it for a while--it's not something that's very obvious. Is this something that I need to worry about? The pool is only 4 years old.

Thanks!
