I added a new bathroom addition to the side of my singlewide mobile home and need help with where I need to vent the new toilet, shower, tub and vanity sinks. The items shown on the diagram above the main line to the septic tank are all new and will connect into the 3" main drain which is already vented at the left end with 2" vent stack through the roof. Do I need to add any additional venting for the new items ?
