Waste, thanks for all your help. The leak was actually found today. Apparently there is a 2" or so diameter hole in the side of the pool just below the water line that is believed to once be possibly some kind of cleaning equipment. In any event, the pool guy missed it on his first round of plugging up holes and when he plugged it today the water stopped running. At least now my water bills will be back to normal!

Thanks again for all your help.
