  1. Hi, I read your article (awesome by the way), and my water leaks until the water level get even with the pool opening for the skimmer. When I look inside the skimmer (where you put the basket) and its still 1/2 full. SO i am a bit confused if the skimmer was leaking I would think inside the skimmer would be empty as well. I am going to fill up the pool again and then use food coloring and see if I can find it leaking….really weird
