ya anomolies these roughnecks can be a pain. there are several ways to deal with the leaks. try holding the outside of the top edge with your thumb and your fingers on the edge of the lid, then pull up and in with your thumbs and push down with your fingers. this pushes the lid down lower than the top edge of the container so the water hits the lid first. or you can clamp it down with those blue clamps you can buy at homedepot or use rope calk around the inside of the lid, but be sure it is in one piece all the way around or buy those black and yellow tough boxes. sorry for the long post but i have tried alot of things and all work somewhat
