Your home’s plumbing system isn’t solely about water. In fact, your system needs proper air flow to keep your drains flowing freely. At the very top of your system is the plumbing vent, or vent stack, that helps regulate the airflow your plumbing needs, keeping the pressure at consistent levels.
The plumbing vent is a vertical pipe that attaches to your drain line and runs through the roof of your house. What you see sticking out of the roof is the main roof vent, which is there to exhaust gasses and to help your system maintain its atmospheric pressure within the waste system.
Your house’s drains carry waste through the pipes to the city’s sewer or to a septic tank. That water has the ability to move unimpeded because the vent pipes supply fresh air to each fixture in the house. You can thank that vent system every time to flush the toilet or clean dishes in the sink.
Draining water out is one of the key jobs of the plumbing vent, but it is also there to keep sewage gasses from getting in. The vent system runs out through the roof, nowhere near windows or air conditioning units, so the exhausted gasses do not spread through your home.
There are some potential problems you might experience with your plumbing vent. A blockage in the vent will cause a buildup of negative pressure in the drainage system, which could either slow or stop the flow of water out of your house. One way you might notice a blockage is with slow drains, or if you hear gurgling sounds from the drains.
The danger of a blocked vent comes with the buildup of sewer gasses. You recognize that problem almost immediately by the odor that comes out of your drains. Sometimes a plunger, auger or drain cleaner can help resolve the issue, but in some extreme cases you may need to call a plumber.
Proper water drainage requires proper airflow, and both require a clear and unblocked plumbing vent.
