vent stack

This is part of series of messages that diverged from the original posting, so I am reposting part of here.
Would extending the vent stack with an elbow so that it goes up above the eave have an impact or would the angle totally ruin the effect of the vent stack.
: That is one of the results of a vent that is terminated through a wall. The other one is that when the wind blows from that direction it can create pressure imbalances which can cause trap oscillation and possible seal failure.

: : Thanks Terry. This will help a lot. I think you have a great site and I am sure I will back with other questions in the future. As matter of fact, I have one now that is related to this. The sewer vent normally goes up through the roof, but in this building it comes out through a second floor toliet wall underneath the eave. Will this configuration work? It seems to me that whenever we have strong winds we get the smells blowing back into the building.
