If the end of the vent pipe is plugged, proper draining will be hampered and air will be pulled into the piping, which will drain the traps of water fixtures. This allows sewer gas into the house. The gas, primarily composed of methane and carbon monoxide, will have an obvious “sewer” smell; however, some harmful gases are odorless.
“The first indication of trouble may be the toilet gurgling or not flushing properly as water is pulled from the traps to replace existing water and air flow,” Scherer says. “Sewer gas may cause people to become sick with symptoms such as headache, nausea and/or dizziness.”
