I would like to connect a water hose to a bucket or a barrel to feed my automatic waterer. What size and kind of connections do I need to buy and does someone have a pictorial example? I usually can figure things out if pointed in the right direction, but our local Home Depot plumbing guy is an idiot. He looks at me like I'm a snake with two heads when I come in to ask questions. He of course asks me why I need this and I tell him its for my chickens, I'm making a feeder for my chickens or a incubator. He just doesn't get it.
