What does a vent pipe do in a plumbing stack?
A vent pipe (plumbing stack) is in charge of distributing air so the water can flow through the main drain pipe without any restriction. Moreover, besides allowing the air into pipes to ensure smooth wastewater flow, without gurgling and without creating a vacuum, the stack pipe serves as a “trapdoor”.
Is there a vent line for a basement toilet?
When we bought our house the plumbing drains for a basement bathroom were roughed in but they did not install any vent lines for them. We have the first floor plumbing draining into the main stack which drains down into the concrete of our basement and out to the street.
Can a vent be bent towards the stack?
This might prevent you from doing what you want, since your lower horizontal connection would have to slope toward the stack.

Can a plumbing vent go up and then back down?

What happens if you don’t have a vent stack?
Without proper venting, flowing water creates negative pressure that can slow water flow and empty P-traps. Every fixture must have its own vent that must terminate in open air, but in most houses, only one vent pipe goes through the roof. The fixture vents all tie into this pipe, which is called the main vent stack.
