yes.
If the drain is used as a wet vent for another fixture 2". Otherwise 1.5".
Install an automatic air vent on the line
Vent piping is a pipe that runs outside and is connected to the drain line of your home. this helps the water in the drain to move to your septic/sewer.
Take your snake on the roof and clean the drain from the vent.
dvw pipe = drain, waste and vent pipe.
The drain pipe should have a vent that goes up where the sink drain goes into it. That is where it vents. Sinks drain because there is nothing causing a vacuum when the water leaves the sink.
No.
There is an overflow pipe on every tub. There is no further need to vent.
No. You vent air from a sewer line.
Make sure the drain line and the vent are cleared. Noises like that are usually caused by either restricted flow or a plugged drain vent.
A vacuum is being created at some point after the two drainage pipes meet. This forces air back up the other pipe and through the "U"-bend underneath the sink, causing the water to gush upwards and drain again, making the gurgling sound. Since both the bathroom and kitchen gray water supplies contain no sewage, this not harmful.
