If you notice a foul smell coming from your bathroom’s sink or the
drains, it may be due to sulfur. Not the kind you find in volcanos, but
hydrogen sulfide gas produced by bacteria.
Detecting the Origin of the Smell
The smell can come from a variety of places, such as the sewage, the ground,
as well as contaminated water and pipes. It can be difficult to determine
where exactly the smell is coming from; however, you can conduct a simple test.
To check if the problem is in the drains or in the water, do the following:
- Fill a glass of water from the drain or the area you believe the smell
is coming from.
- Go outside with the glass of water and smell it.
- Check water from another faucet and take it outside to smell.
- If both glasses of water have a foul smell, bacteria may be present in
- On the other hand, if only one glass smells, then one of your drains is
If your drain smells like rotten eggs, you must disinfect the pipes to
get rid of the odor. You can eliminate the bacteria by pouring a ½
cup of bleach down your drains. However, if you would like an alternative,
you can pour ½ a cup of baking soda, followed by a cup of vinegar.
Your water heater may be contaminated due to the magnesium from the anode
rod reacting to the bacteria. To fix this, you can just replace the rod
with an aluminum version and disinfect the water using hydrogen peroxide.
