Why does it smell like sewer under my bathroom sink?
A rancid odor coming from your sink drain may just be coming from debris in the P-trap, but if it smells like a sewer, it probably means venting problems in your drain system. When the vents are blocked, flushing a toilet can create sufficient vacuum to suck water out of the trap and allow sewer gases into your home.
Why does my bathroom sink drain smell like sewer?
There could be odor-causing bacteria feeding on debris in your pipes. This process will give off a foul-smelling hydrogen sulfide gas, which smells like sewage or rotten eggs. Also, mold grows where it’s warm and wet — and mold growth on the debris causing a drain clog can also cause a bad smell.
Why does only my bathroom sink smell like rotten eggs?
If you are noticing the smell of rotten eggs, it is possible that your water or sink drain is contaminated. It could also be that the drain is clogged or partially drained. When sinks are clogged, they drain slowly, which can cause bacteria to build up in the p-trap and create the hydrogen sulfide gas.
