stink pipe? any fixture connected to any drain line in your home should be sealed off from any sewer smell from a trap, and yes if you have a trap it should have water in it. If its a floor drain that isn't used much I recommend you pour a little bit of vegetable oil down it after you pour water and that seems to correct a trap going dry for a long time.
Not only can it be cleaner it should be water jetted every few years to make sure there is no residue hoar frosting.

Every building has a "stink pipe." Usually located on the roof these pipes vent air to allow the plumbing drains inside the building to work correctly. As water flows into a plumbing drain pipe, air is vented out of the drain through the "stink pipe." The pipe that goes from the bottom of the back of your toilet, up the side of your house to let any gases produced by the waste escape into the air instead of bubbling back up through your toilet and sticking up your house.
No water does not help. You should brush and/or use mouthwash.
