I just bought an igloo extreme rectangular 60 quart cooler. I also bought a standard 3/4 inch bazooka screen. My problem is the cooler drain is on the backside of the cooler instead of the instead of the side. I went ahead and installed the screen but I am concerned that since the screen is not going across the length of the cooler I am going to lose effieciency. Another concern is the screen is not resting on the bottom of the cooler and the bazooka screen is pretty rigid and difficult to get it to stay at the bottom. Will the grain bed weigh it down enough to get it to rest at the bottom? Any suggestions?
