I'm not a plumber, but I have used these before. My understanding is that the screw cap is opened just a bit so air can escape. If it's leaking water probably means it's rusty and corroded inside. it's a pretty simple matter to remove it and clean it, but you have to isolate it by shutting off valves up and downstream from the vent, if you have them. hope this helps.

That stays - it's connected to the vacuum breaker. http://media.wattswater.com/ES-FV-4M1.pdf
My understanding of the paddle is that it should be left in place with the installation and that its purpose is to be disturbed by the fluid flow to keep the vent From developing an "air-lock" that interferes with the flow of bubbles out of the system. I installed all of mine in hydronic heating system with the paddles in place and these work fine.
