I was wondering if anyone can give me an advice on how urgent it is to replace this skimmer. The separation is most likely from concrete deck moving the top portion of the skimmer. The pool is not leaking unless water gets too high to that "separation". I am trying to seal it to prevent moisture coming in there but the main issues is moving concrete. Anyone had similar issue. My second skimmer is fine without separation but they are in different concrete slabs. See pictures
