Fully automatic poultry water cup - The drinking cup maintains a fixed level and automatically stops filling when full. When the water level drops, it refills with fresh, clean water. There are no leaks, spills, or dirty water. Easy installation - Includes hardware and a 3/8 inch drill bit. You can mount the water cup to a bucket or PVC pipe by drilling a hole in the container and screwing the cup on. Water flows automatically to keep your birds supplied. DIY compatible and versatile - Works with quail water dispensers, automatic drainage, chicken water bowls, quail water cups, and other poultry irrigation systems. Installation steps: drill a hole on the side of the bucket about 3 inches from the ground, insert the water cup, and tighten the nut to complete the fit. Keeps birds cool and healthy - By keeping the throat moist in hot weather, it helps cool poultry and maintain throat cleanliness. Cool and clean water supports overall health. Use scenarios - Backyard coop: attach to a bucket reservoir or PVC pipe network to provide a constant drinking supply for chickens, ducks, or quail. - Small farm or mixed flock: install multiple cups along a PVC line for scalable water delivery. - DIY poultry irrigation projects: integrate with existing dispensers and drainage accessories to streamline water provision across the coop.
