Folks,
Brand new poster here.
Spouse and I are building a new retirement residence.
I'm doing the DWV work.
Can a 2" DWV WC vent (PVC - all the way to attic vent manifold) also be used to vent a 1-1/2" basin drain (combined into from basin 6+ inches above basin flood rim)? Or, must the basin vent be run seperately to the attic vent manifold (4")?
Regards, JLB
