It’s important to recognize the signs of a clogged or otherwise problematic vent for the safety of your family. Here are some common symptoms of a clogged plumbing vent:

To take on this DIY plumbing fix, locate the plumbing vent stack on the roof and use a plumber’s snake or garden hose to try and loosen the debris causing the blockage. If these tools don’t clear the pipe, it’s time to call a plumber trained in vent pipe clearing. They can remedy the blocked plumbing vent pipe and advise you on how to prevent it from happening again.

Learn about the importance of plumbing vents for your home plumbing system. Recognize the symptoms of vent pipes not working properly and what to do.

An air vent for plumbing that doesn’t work properly will negatively impact your entire home’s plumbing drainage system. When a plumbing vent pipe or vent stack is blocked, a vacuum is created in the drainage pipes, and water flow is interrupted. Though you may have success clearing a clogged drain yourself, stoppages will continue to occur if a blocked vent is the culprit. Any ongoing stoppages and slow-flowing drains can lead to sediment forming inside the drainpipes. This can further damage your plumbing system and may result in hefty pipe repair or replacement costs down the road.

In the walls, vent pipes run straight up and down and should be located near the kitchen and bathrooms. Note where the pipe enters from the ceiling. If you have a two-story home, go upstairs to locate the pipe. You can verify whether a pipe is a vent pipe by listening as someone flushes the toilet. If the pipe amplifies the flushing sound, it’s likely the vent pipe.
