Question 1

1. Is the Rotten Egg Smell Coming from Water or the Drain?

Accepted Answer

If your sink smells like rotten eggs, it’s highly likely that the smell is coming from your water or drain. However, it’s not likely that the water smells that bad and it could possibly be the bacteria in your drain. When the drain gets clogged, it can result in the growth of bacteria which then gives off a pungent smell of hydrogen sulphide.

Question 2

2. What Is Causing the Sulphur Smell in My Sink?

Accepted Answer

Sulphur smells could be coming from your water or the drain, and it’s not at all pleasant. The smell is usually of hydrogen sulphide which is produced by bacteria infestation in the ground or in contaminated pipes and drains. The reason could be a clogged drain, dried or emptied p-trap and dirty garbage disposal.

Question 3

3. What if Rotten Egg Smell Still Persists after Cleaning the Drain line?

Accepted Answer

If even after cleaning your strain, two or three times the smell remains, you can try a few other options. Sometimes when organic matter gets trapped in the water heaters, it releases sulphur like odour. The tank may then need to be disinfected or the debris needs to be cleaned. If nothing works then you can consult your plumber and have tests performed.
