Hi, I am new here. Just spent the past 3 days setting up and filling our Bestway 16x31.4 rectangle above ground but noticed today about 3 inches from 90% capacity that one of the corners is not square. One side is less into the top rail than the other side and seems to be putting so much pressure on that the top rail has started to split. Will the pressure equalize or do we have to drain? TIA. Pictures attached.
