New pool under construction,. So far they have dug, plumbed and steeled, shot the concrete and just finished tile around the water line. One of the skimmers is 1/2" off level from side to side. Also on that one, it seems much more decline from the interior of the pool into the skimmer relative to the other skimmer. They still have the flagstone coping to cap the pool edges and over the top of the skimmer. I know it's not right and it bothers me especially for what it cost but will it cause any problems doing it's job? Also, I am concerned that at the deck level they won't be able to finish the concrete off level due to one side of the cover tube being slightly lower than the other. I have not told the 'builder' as of yet. Any thoughts/suggestions/recommendations? Thanks
