As a student, I lived in dorm-rooms for all of 4 years. I had fairly luxurious rooms, and every one of them had a bathroom. However, in the first year, my room smelled absolutely disgusting. I was on the first floor, and whenever someone above me would shower, sewer odors would escape from the kitchen sink and shower.
Even though I took good care of my plumbing system, cleaning it frequently and thoroughly, nothing helped the smell. Months later I found out why. Firstly, there was no p-trap installed anywhere in the building, and the building itself was quite old.
Therefore, even though I cleaned my bathroom and kitchen every 7 days, that doesn’t mean my predecessor did, right? And with all the other stress that came with moving to the new city, new school, and exams, I became resigned to the smell. I just kept my windows open.
Thankfully, I remained healthy. It should be emphasized that no one should resign to my technique.
To continue, I mentioned this interesting thing called a p-trap. Let’s see what it is.
