4 Common Plumbing Odours and What They Mean

Have you ever smelled something funny coming from your plumbing system? While most of the time, this is not a cause for alarm, the foul odour can sometimes be quite annoying. However, for you to be able to address this problem, you have to know the root cause. This article lists down some of the most common plumbing odours and what they mean.

Rotten Eggs

When the smell coming from your plumbing system is similar to the smell of rotten eggs, then you may want to check for a sink overflow. It is possible in this case that bacteria have already built up in this hole causing the smell. In this case, what you can do is to clean your sink overflow and hopefully, the smell will subside.


In case the water coming from your tap smells like sulphur, then it is most likely that the issue is with your water heater. This is particularly true when the smell only occurs when you use the hot water from your tap. While this is not hazardous, it can cause a certain aftertaste in your water. In this case, apart from taking a look at any problems with your heater, you may also want to consider installing a water filter.

Sewer Gas

If you smell something like sewer gas in your bathroom, then there might be leaks in your plumbing system’s pipes. Even damage to your toilet wax ring can bring forth a smell like this one. If the cause is the latter, you may need to replace the ring. Otherwise, you may need to get the help of experts who will be able to help you address the problem accordingly. Call an emergency gas plumber servicing around Five Dock as soon as you can.

Garbage disposal

Finally, when the foul odour you smell is similar to that from your garbage disposal, then you may want to take a look into its splash guard. When you notice that this is already dirty, then take the time to clean it to eliminate the foul odour. Make sure to scrub away all the grime you find before you rinse with hot water.
