When opening an overhead cleanout in the basement, tie a heavy-duty plastic trashbag around the cleanout, leaving room to get your hand in to remove the cleanout plug that you previously loosened. Cut a small corner of the trashbag bottom and put a 5-gal. bucket under the hole. Carefully open the cleanout and all the water and debris is funneled through the bag into the bucket — with no mess on you or the floor.
