Vent system

I do not understand this vent system. Any thoughts.

Thanks

Looks fine to me but I’m not a CMI :wink:

WHAT AN ***!!! I guess you know everything there is. I have never in 8 years seen anything like this. Why? can’t anyone give a straight answer. Maybe it was not racist or political enough. I am glad never had to count on you in a firefight.

I would if I knew, but I ain’t ever seen one like that either.

Thanks!!! Larry. Only one vent out the roof.

Get some skin will yah.

It’s just a rough-in for a sink shower and toilet.

They need a dry vent and that’s why it looks strange to you.
