Hello, I have a newly installed Shower Vent/fan that just currently just exhausts the moisture into my attic.

My Question is, can I link the SHower Vent to an Existing VERTICAL Vent Stack? I'm imagining just cutting the Vent Stack and put in a WYE ABS fitting, connect the Shower to the WYE fitting, and the air/moisture goes out the stack.

Is this to code/legal? Will it work?

The reason I don't want to go Horizontal and put in a new vent tube out of a wall is because I don't have a hammer drill and bit to punch a 3" or 4" hole in my exterior wall.

Do I just bite the bullet and go Horizontal?

In my mind it seems easier to go Vertical using a Vent Stack.


Thanks guys!
