Joe started dealing Jugs in the early 80’s, and Cowco,inc started working with jug in the late 90’s. Jug waters are backed with the strongest warranty in the industry. Animals do adjust easily to the new style of drinking from the Jug waterers. Jug has a unique draw tube design with a feed trap to keep the water clean.  Jug has no lids, flaps, balls, or disk, creating an open bowl design.  Jug has an external drain plug and an external float adjustment.
