Sewer Vents

Each fixture needs it's own vent connection that goes to the main vent line. Click on the link below for a typical drainage system set-up. Notice that each fixture has a line going to the main drain, and also a line going back to the main vent.


If you have never made a mistake, you haven't done much.
