Ok... DH went to Lowes and got the adapter and it now works BUT how do I adjust it, how far do I fill the ball thing underneath... basically, how do I set it up to work. There were no instructions with it and I don't know what I am doing. Thanks so much.
I bought a waterer off of Craigslist that looks like this...

The person I bought from said you can attach it to a 5 gallon bucket but... I have no idea how to do that and what parts I need to make that work. Any help would be appreciated.
