Why Your Home’s Sewer Lines Need Venting and Signs the System May be Failing

In addition to water lines, sewer lines and gas pipes, there is a network of ventilation pipes that lie hidden behind the walls of your residence. These pipes are critical to the proper functioning of your sewers. Without them, the waste from your toilets and other plumbing fixtures would struggle to leave your home. That’s why it’s so important to know if your ventilation network is failing. We’ve listed some tips on how to know if it’s failing to function as it should be.


Why a Ventilation System is Needed

Without vents that permit air to move in and out of the system, vacuums will form behind wastewater. The “pull” on this wastewater will prevent it from freely flowing downward. The ventilation system not only prevents vacuums, it also prevents pockets of air from forming ahead of the wastewater flow. These pockets could lead to a situation where pressure is high ahead of the wastewater, which would also restrict flow.

The ventilation system also has an important role in getting rid of the accumulation of sewer gases. Roof stacks allow these noxious gases to vent harmlessly into the atmosphere instead of escaping you’re your residence.
