I have made one it does not look exactly like that but close. If you go on Ebay you can buy the cups with the "Y" connectors for cheap like $12. I made mine with 1/2" PVC up to a 5 gallon bucket. I drilled a 3/4" hole in the bucket slipped the PVC pipe in and then glued a 1/2" connector so it would stay in the bucket and be water tight. It works really well. My 5 week old chick are at the point now they peck it and water comes out. It is so nice not to have to clean a water bucket out every day. There are a few tutorials on Youtube and Pinterest.
I hope to get one built before summer.
I'm worried about leaks too.
The nipples leak maybe not at first but they will after a little while and from everything I have seen they make a mess. The cups are great, the only time there has been a mess is when I overfilled the bucket. I have seen people put them right in a 5 gallon bucket and set the bucket on a block the only reason I did not do that is I did not want them roosting on top of the bucket because you have to drill holes so the water will flow down the pipe.
