Quick question on the size of vent pipe I should run through my roof.
I have a basement bathroom with tub/shower, toilet, sink and bar sink. The bar sink has a grey water pump and there is an ejector pump. Pretty much everything is vented with 2" pipe, and all those go into a pre-existing 3" pipe that the builder had put in. This 3" pipe goes up 2 stories to the attic. Can I neck down the last 6 feet or so, to go through the roof with 2" pipe or should I stick with 3"?
Also, do I was planning on protruding through the roof about 12-18"...
So, 3" or 2" through the roof?
Thanks...Mike
