Well, I started building my deck. After digging my holes for my footings yesterday I went out this morning and one of the holes closest to the side of the pool has about 3 inches of water in it. This particular spot is the lowest side of my pool so it would make sense that if my liner has a hole in it it would all run to this spot. I did find a little hole in my liner about the size of a pencil eraser cut in half. could this be where the water is coming from or is there a bigger problem?
