How to Stop The Sewer Smell Coming From Your Sink
- 1
Sink stopper
Plug the sink using the stopper. - 2
Sink filled to overflowing.
Fill the basin with water to the overflow hole (the little hole at the front of the sink). - 3
A cup of chlorine should do it.
Add a good dose of Clorox or store-brand chlorine to the water. I used a cup or so the first time I cleaned it for an extra-deep sterilizing. - 4
Add more water.
Add more water until water is slowly but steadily flowing into the overflow. Do not get the water so high that it goes over your sink! - 5
Waiting for a clean sink.
Turn off the water and let the Clorox water sit in your sink for a few hours, adding more water occasionally to the sink to let the mixture get into the overflow to disinfect. - 6
Clean and safe. No foul smells here!
After you've disinfected the overflow sufficiently, partially release the stopper so that it drains v-e-r-y slowly. This will allow the disinfectant to clean the underside of the stopper, the rod that operates the stopper and the trap under the sink that prevents sewer gases from entering your house. You should have a sparkling clean sink basin and below.
