First and foremost, what is the source of the sulfur odor coming from the drain?

It’s hydrogen sulfide, one of the numerous molecules that make up the gas present in sewage, that makes your drain smell like rotten eggs.

You may do a simple test by yourself:

  1. Fill a glass with water from the smelly drain in the sink.
  2. Take it outdoors and give it a good sniff.

If the water smells sulfurous, pour another glass of water from a different sink and repeat the process. It’s most likely the water if both glasses of water smell like rotten eggs. If you’re the only one experiencing a stinky drain, it’s most likely the drain itself.

What causes the sulfur smell in your drain?

Several factors might cause a foul odor in a drain. A blocked or partially clogged drain is the most prevalent. Sinks that are blocked drain slowly, allowing bacteria to grow in the p-trap and produce hydrogen sulfide gas.

It might also be caused by a sink that hasn’t been used in a while since when the water in the p-trap evaporates due to inactivity, gas from the sewage line can escape via the drain.

Clogged trash disposal is a typical culprit in the kitchen. Food and germs can build up in the drain, making it smell bad.

What to do about the sulfur smell in the drain

There are a few things you can do to keep sulfur from stinking up your bathroom or your kitchen. First, ensure sure your waste disposal is in good working order. Run it regularly and clean the blades with a garbage disposal cleaner or ice cubes. A few lemon slices might also assist in masking or eradicating the odor.

You may eliminate a blockage in your bathroom drain by putting half a cup of baking soda into the drain, a cup of vinegar, then flushing with hot water. If it doesn’t work, you might need to seek expert assistance.

It might be as easy as a regular blockage or an empty p-trap if your drain smells like rotten eggs in your kitchen, bathroom, or shower. It might, however, be something more serious.
