Why does my water taste of sewage?
Drinking water and wastewater are supplied by different pipes, so contamination of incoming clean water is rare. Bacteria in drains can produce sewage odours that can be released when disturbed by running water.
What to do if your water taste or smells of sewage
Determine the cause
If you think your drinking water smells or tastes like sewage, this may be due to your kitchen sink drain. To test what the cause is:
- Fill a clean glass with water
- Bring it to another room of the house
- Smell the water
If the smell has gone, then the odour was likely from the sink drain rather than the incoming water.
