Now you see them (note, I have the forward drain latched in the open position)
Now you don't.
Older interiors may have a smaller cover over the valves, but on this newer B200 you need a Phillips screwdriver to remove the panel to see if the valves are open or closed.
Worst part is I've never seen water come out of a KA static system, short of attaching a pressure washer to the static ports, it is about impossible to get water into the system, the plumbing runs straight up from the ports to the top of the airframe before going back down.
