Zitacuaro place

Hi, I want to know if sewer gases are harmful to human health? The gases are coming up our drains in our apartment.

There is no drain trap in the bathroom sink drainage and no drain trap in the washing machine drainage.

The smell comes from all the drainage pipes in the bathroom, sink, washing machine and shower.

Thank you!

Yes, it could, and NEVER assume anything about construction. The P-traps could be underneath the floor level (perfectly legal). Call a plumber. Be prepared to pay for his service. And NO, you do not have the right to withhold paying your RENT! If you do, you will be evicted! (again… perfectly legal).
