I recently finished my brooder, and decided to build a gravity waterer to minimize opening up the top. As you can see in the pictures, it is a 5 gallon bucket connected to a ball valve that feeds a hose and 1/2" pvc pipe, which I put into a 3" pvc pipe. The opening in the 1/2" pvc sits on the bottom of the 3" pipe. I thought I had it working, but after a couple of hours it starts to seep out of the holes I cut for the chicks to stick their heads in. With that being said, is there a flaw in my design, or am I missing the concept of a gravity waterer? The only thing I can come up with is maybe my bucket is not completely sealed. Hopefully someone smarter than me can steer me in the right direction. Thanks for any help!
