I'm getting sick of going to close the pool with a whole new batch of water bags and having 1/2 of them leak out of the box. I was getting them at Ocean State Joblot. This year I got them at Leslie's this year and the closures are nicer, but still half of them leaked. I'm about ready to just start paying the pool company to do it for me because the year I had them close my pool I didn't seem to have any problems with leaky bags.
