Intermittent Lingering Smell Coming from Bathroom Vent
For around 3 months now, there has been a foul smell coming from my bathroom vent. It initially smelled like horrible, putrid, rotting garbage which made me physically ill and could be smelled throughout my apartment. The smell would come and go, seemingly at random and not connected to any particular time of day, weather pattern, etc. Sometimes the smell would last hours, sometimes minutes, sometimes weeks without the smell, sometimes daily smells. I ended up covering the bathroom vent, and the smell only appeared to recur once. After a good month and a half without any foul order, I removed the cover from the vent, but the smell has since returned. This time the smell is much weaker, but smells of poop. On one occasion, it smelled like onions. I live in an apartment community and have been waiting for over a week for the maintenance guy to take a look. I want him to come when it smells, but it is really difficult to catch. According to a neighbor, he had sewage smell in his apartment which made him pass out. The vents on the roof were supposedly cleared and other tenants are reporting an improvement of smells and they found no issues with the pipes. What could this possibly be?
