I have changed my water system, and no longer need this nipple unit - good for a small flock. You can use any container that you can drill a half inch hole in. It screws on easily, and you're set ! The whole thing can be detached , and submerged for cleaning/disinfecting. My girls learned to use it in about 10min - smarties ! $30 new - well made - price includes shipping - great deal !
