Lisa,

Welcome to the forum!

There are vent caps you can use inside that have a spring loaded flap. When there is a vacuum in the pipe it opens to allow air in. There is no smell from them because they are normally closed.

Did you buy the home new? Is there a warranty on it? Can you check with the manufacturer to see if a mistake was made and the vent pipe was not completed and is is just an open pipe in a wall cavity?

If you get into the attic space is there an open pipe coming up into this area? If there is you can extend it through the roof to vent outside.

Please let us know what you find.

Good luck, Jim
