I'd have to make another water system to create a "how to" video - you're just going to have to get creative. Farmtek tells you to use a 11/32" drill bit for their push-in nipples. It's a tight fit but they don't leak.

The rest is basic 1/2" pvc pipe plumbing.
Every system will be custom made/sized to fit your needs.
My system used:
1. 3 - 90 degree elbow's.
2. 1 - Tee
3. 2 - caps
4. 5/8" vinyl tubing.
5. 2 - Plastic nipple fittings for the tubing (1 - straight, 1 - 90 degree)
6. Bucket fitting, 1/2" pvc pipe to 3/4" hose threaded fitting.
7. 3 gal. bucket from Home Depot.
I drilled the caps for the nipples using the 11/32" bit. I drilled the bucket using a 3/4" paddle bit. I suggest going to a good hardware store and telling them what you are doing and ask them for the 3/4" bucket fitting with O-ring and nut & washer for the inside. Just keep your flow going downhill and it will work.
The treadle holds about 15 lbs. I'm on the grow mix right now with a little hen scratch for fun.
Training: You stop it open for a few days. Then you set a stop so the action moves half way for a few days. They can still see the food but get used to the movement of the treadle and and lid. Then, you take out all the stops and they're on their own - no problem. Hunger is a great motivator.
They went right to the nipples. According to Farmtek the red color piques their curiosity and then when water comes out, bingo! Their little bird brains make the connection.
I'm beginning to think all my chickens are roosters.
