What is likely happening
Discolored or reversing water can mean a cross-connection or backflow event, or disturbed sediment in the mains. Until it is understood, the water should not be used for drinking.
What you can safely check
- Stop using the water for drinking and tell occupants.
- Contact your water authority.
What an inspector will look at
- Backflow assembly test
- Cross-connection survey
- Flushing plan
Does this affect compliance?
Water authorities treat backflow events seriously and may require immediate testing.
When it becomes urgent
