ABSTRACT:
The present invention relates to a conduit drain for removing liquid condensation in a vertical conduit. Moisture flows down the interior walls of the conduit and collects in a collection lip in the conduit drain. A drain channel is produced around the inner circumference of the conduit drain by the collection lip. The moisture collects within the drain channel and is drawn off into a drain port that is coupled to a drain pipe.
