Plumbing vents are a critical part of your plumbing system's air pressure balance and proper drain flow. Unfortunately, many homeowners don't even realize that plumbing vents exist, let alone what it means when there's a problem. Your plumbing vents can become clogged and blocked, which will disrupt your plumbing system's drain flow in a hurry. Here's a look at some of the things that you should know about blocked drain vents so that you can address the problem.

What Are Some Signs Of Clogged Drain Vents? 

When a drain vent is clogged, the air isn't able to flow in and out the way that it's supposed to. That air has to go somewhere, so you might notice that your drains and toilets start to bubble and gurgle when they drain. If this starts happening throughout your home, that's a key indication that you've got a blocked vent that's interfering with adequate airflow.

In addition, since those vents are supposed to allow sewer gasses to vent out away from your home, you might start to notice foul odors from your drains when the vent gets clogged. If it's blocked, those gasses can't drift out and away from the house. That means they back up into your drains and are released into your house. Persistent sewer odors are another key indicator that your drain vents need attention.

If you notice either of these symptoms in combination with slow draining from your pipes, there's a good chance that those vents are clogged. Without the right air pressure balance, your drains won't flow the way that they are supposed to. This causes slower draining. Since slow draining can also be indicative of clogs in your drain pipes, it's important to consider the other symptoms as well to determine if it's connected to your drain vents.

How Do You Address A Clogged Drain Vent?

If you have reason to believe that your drain vent is clogged, it's in your best interest to talk with a local plumber. They can come out and clear the blockage with a pipe snake or other similar tools, restoring adequate airflow. You may also find that your plumber replaces the vent cap on top of the pipe, which will help keep leaves and debris out of the vent line. These things are the most common causes of clogs in the vent lines, so it's important to prevent them.

These are some of the things you should know when it comes to dealing with plumbing drain vent clogs. Talk with a residential plumbing service today if you have concerns.
