Our dog fell into our inground pool and sadly ripped a hole in the corner about 2 feet wide and 18 inches deep. part of it is underwater while part is above the water line. How should we patch this? we went to watsons and bought a repair kit, but then we had to glue several pieces together and it isn't working well to patch it under the water very well. any advice on what to use, and meanwhile what should we do? let it drain on it's own, should we drain the water ourselves?
