Greetings,
This is probably very simple but just want to confirm if I can use an 1-1/4" dry vent for a kitchen sink that will have a dishwasher and disposal. The trap is 1-1/2" and the drain is 2". The vent will go through the roof and is about a 20' run. There was an existing 1-1/4" galvanized that I am replacing (100 year old house) and would rather go back with the same size rather than drilling larger holes through the studs.
Many thanks-
