Sewer vents are located on the roof of your house. They allow the gases that build up in your sewer system to escape.<\/p>\n\n\n\n
Work on a vent pipe is very difficult and if it involves getting on the roof, potentially very dangerous. It’s strongly recommended that you contact a professional plumber if you suspect that your sewer vents are clogged.<\/p>\n\n\n\n
There are 3 main signs (i.e. symptoms) that indicate that your drain vent pipe is clogged.<\/p>\n\n\n\n
1. Slow drains<\/strong> – As I mentioned earlier, if a vent is clogged it can cause the fixtures attached to that vent to drain slowly. This is a very common telltale sign.<\/p>\n\n\n\n 2. Toilets make a gurgling sound<\/strong> – A clog in the vent restricts airflow through it. As a result, the pressure in the pipeline then increases so when you flush the toilet, the water has trouble going against this pressure and the result is a gurgling type of sound.<\/p>\n\n\n\n 3. A strong sewer smell<\/strong> – Because the clog is causing an increase in pressure in the pipeline, gaseous odors are also blocked from flowing out of your home.<\/p>\n\n\n\n
