Plumbing Question: What Does a Drain Vent Do?

At Modern Plumbing Industries, Inc. (MPI), we have seen a wide variety of plumbing jobs throughout the Orlando area.  We believe that an informed customer is a great thing; it allows you to spot any issues or problems with your piping that may cause clogs and leaks. It’s relatively simple to understand that drains needs to be installed at a pitch so that gravity can push your organic waste and gray water into your sewer. But your drain ventilation system is just as critical. In today’s post, we’d like to address what a drain vent does. If you have any issues with your plumbing system that need professional attention, give us a call today.

Your wastewater disposal system cannot work without proper ventilation. Think of your drain as a tube plugged at one end. Without ventilation integrated into the drainpipe, that wastewater cannot move because there is a pressurized vacuum. A drain vent pipe connects your drain to what’s known as the main stack. While its location may vary from home to home, the main stack ventilates your drainpipe system all the way through the roof. This allows for air to flow into your drainpipe, thus relieving the pressure of a closed system, and letting gravity do its job to keep your home a hygienic and pleasant place to live.

As you can imagine, your drain vent is subject to wear and tear and problems just like any other aspect of your piping system. If there are any blockages in your drain vent, whether at the local pipe itself, or within the main stack, then you simply cannot expect effective and efficient waste removal. This may cause odors to develop in the home or might even completely backup your plumbing. It’s critical that any such problems be addressed by a professional plumber so that your home is restored to its normal operation.
