Recently, my bathroom sink started smelling of sewer when we are running water (hot or cold water). It is the only water/drain in the house that does this. All other water/drains are performing as normal.
The room also has a tub, shower, and toilet. I disassembled the sink drain p. This localized buildup is common in bathroom sinks and showers, garbage disposals, and sink overflows where stagnant water and debris accumulate.
The smell is generated by bacteria feeding on these deposits, and the running water pushes the odor into the room. When your bathroom sink smells when running water, it is likely due to bacterial buildup in the drain caused by grease, fat, and food particles. To clear the smell, you can try boiling water, using a plunger, applying white vinegar, or using caustic soda.
To get rid of a sewer smell caused by lack of water in your P-trap, run water in the sink. If running water doesn't work, try using antifreeze and checking for leaks. If your bathroom smells like sewage, you may have a serious plumbing or ventilation issue.
