I made 2 five gallon waterers with buckets and the nipples. I hang them and they work just fine. I do have to dump them and clean them, but it's only about once a week. Way better than the traditional waterer. But, I see the benefits of the water line. Then the water is always fresh. My friend put the nipples right into the PVC pipe for his birds. Didn't need the little cups. He's very happy with that.
