What is a Dry Vent In Plumbing?
The definition of a Dry Vent System in plumbing indicates only air can transport through it, and no water is present in the Dry Vent.

Final Thought on Dry Vent
The third component that is important while building construction is Plumbing System.
The vent invent is usually made for air movements, so every time you flush the toilet and pressure that water pushed down, it also forces the air down.
The air moves within the whole plumbing system all the time in the drains and all vent pipes, so what if the vent actually does it it relieves the pressure and it brings in the air to balance out the system.
Therefore, the system is always designed installed to be able one inch plus or minus water column.
That means the water level should move more than one inch up or down at a time, so as the water flows down it’s dragging air with it, so this would be going out to open air.
The vent pipe actually pulls air to balance out the pressures within the whole system if, when you flush this toilet you get this big rush and pushes the air up and out of the room, and then it’s just a circulating system, it’s very similar.
If you don’t have a good venting system what happens is whenever you flushed the toilet maybe the air pressure will lift that water in that P- trap and try to stick that water back out of the P-trap.
Once that trap seal has broken, you have an experience that sewer gas coming out from the system.
