Vent Stack

[blazenut]

I inspected a house recently, a small ranch, whos main plumbing stack made 3 90 degree turns, before it went through the foundation, and up the outside of the home, and finally terminated below the eave about 6 inches from a window. Other than it not going through the eave and terminating above the roof line, do you see any problems with the vent stack having all these turns?

Correct me if i'm wrong but vent stack should not have more than 2 90 deg turns. before exiting and shuld have no diameter changes.
