An accuaintance of mine said he used a type of one-way vent cap for his addition -vent that terminated in the attic. He said that it allowed air to flow down into the vent but trapped the odor from rising up and out the vent cap. Wonder how wise this arrangement is.

Thanks. His is terminated in the attic. He said that he’s going to run it through the roof some-next-summer-day. And like I say it is in an addition; he allready has a soil pipe through the roof.

I did some plumbing for a friend and we installed 3 of them. The code inspector told us we could have run them all up to the second floor attic and used just one... I then said if I ran them all that way why wouldn't I just run them out the roof??? The inspector said that some people don't want to see pipes sticking out their foor.
