By placing the waste 2x the diameter above the opening
No. You vent air from a sewer line.
The vent terminal is allowing down drafts to enter thus one would have to install a return bend on this pipe to prevent the air from entering but it will allow sewer fumes to escape
It allows sewer gases to safely escape.
Install an automatic air vent on the line
The highest 4 inch pipe should have a vent on it, or directly above a toilet junction Above the flood level rim of the fixture it is servicing IT does not mean the toilet
put it on ya stink pipe
that pipe come from the gutter and its a very bad smelling experience as you have experienced before.
A toilet may bubble due to a clog in the drain pipe, a malfunctioning vent pipe, or a problem with the sewer line. This can cause air and water to be trapped, leading to bubbling when the toilet is flushed.
To properly install a bathroom exhaust fan pipe, first determine the best location for the fan and pipe. Next, cut a hole in the ceiling or wall for the pipe to go through. Install the fan and connect the pipe to the fan outlet. Secure the pipe in place and ensure it vents to the outside of the building. Finally, seal any gaps to prevent air leaks.
A vent pipe is located afte a fixture trap to remove dangerous fumes from the system and exhauts them through the roof terminal as the fresh air enters through the fresh air inlet
No, it won't carry the required amount of air. A vent is usually 1.5 inch and an exhaust is 4 or 5 inch.
You must maintain a 2" air gap from indirect waste to sewer waste. If sewage back up was the issue, I would recomend "directly" piping the 2 inch drain to the main sewage with a 2 inch normally closed backwater valve. If you piped an indirect drain you would not be protected from sewer back up. I assume this is for a sink perhaps in a basement?
