Ask a Raleigh Plumber: What’s a Drain Waste Vent

Posted by John Dietz

To say that the plumbing system in your home is extremely important to your day to day life is really a huge understatement. Whenever you brew coffee in the morning, wash your dishes, use the bathroom or brush your teeth, your plumbing system plays an integral role in the successful completion of the task at hand. Even so, many homeowners do not have much of an understanding about what the different components of their plumbing system are, or how they work together to improve the quality your life every day. Here is some information about drain vents and how they work from the Raleigh plumbers at JD Plumbing, Heating & Air Conditioning.

Your drain waste vent is the part of your plumbing system responsible for removing sewage and wastewater from your home. It also regulates the air pressure within these waste pipes in order to ensure that it flows properly. The venting system uses pipes which extend from the waste pipes to the open air outside to release sewer gases. Additionally, these vents allow oxygen into your waste system, which allows for aerobic sewage digestion. These vents also help to maintain proper pressure on either side of your drain trap. The purpose of a drain trap is to maintain a small amount of water which helps to prevent sewage smells from making their way back up into your home.

By maintaining neutral air pressure within your drains, drain waste vent systems are able to facilitate the flow of water and waste down your drains via gravitational force. This means that no sort of pump or any other mechanism is required to keep waste flowing away from your home effectively and hygienically. In some situations, depending on the design of a home or its surrounding geography, an ejector pump may be necessary to keep the sewage flowing outward properly.
