Don't even know what that is. The drain is just a rough circular hole in the concrete slab floor, with a burned-out pot placed on it to keep mice and bugs from using it as a way into the house. Pretty sure that the mouse i stepped on one winter afternoon (while wearing sandals) had just come up from the drain, because it appeared seemingly from nowhere.
