Hey Brother I usually put rocks or brick in water pans to help with heat control. As far as liquid you can use ANYTHING you like. Depends on the cook. In my experience it varies depending on the protein you cooking. Large cut with lots of fat like pork butt create lots of moisture in cabinet. So using heat bricks in the pan helps extend cooking time and works great to help control temp. I tend to dry cook these type cuts. Smaller cuts like ribs or chicken do much better with liquid in the pan to keep moisture up, slows cooking time allowing for longer smoke better smoke penetration and a moisture finished product!!
I think dragonsfire has a great suggestion about using cleaner water unless you have a filter. Are water is great here never had a flavor issue. I'm also in the school of adding flavored liquids really does nothing. I've eaten a thousand beer can chickens. And can never taste any beer flavor. More about retaining moisture.
But that's just an old salts opinion!
Cheers mate
