shut off valve
Normally, a reflux still does not have a "worm" in the usual sense. In a reflux still, the "steam" passes up the column, condenses back into liquid when cooled at the top and passes back down the column where it mixes with new steam coming up (simplified description). This refluxing can go on for an hour or more - depending on how pure and strong you want your eventual product. If you do not shut something off, no refluxing will occur and the rising steam will condense and run into your collection vessels.
(I have the flu and trying to simplify this response. Think I need to try some of my product).

Not for the cooling water unless you want to use it to regulate the
amount going to seperate parts of your still as in a mutiple cooler
