True information gain
When Brisbane flooding may point beyond the toilet fixture
Competitors cover ordinary blockages and fixture faults, but not the diagnostic context created by Brisbane’s floodplain setting, heavy rainfall and creek flooding.
- Brisbane City Council distinguishes Urban Utilities sewer overflows from overflows originating on private property.
- The Flood Awareness Map provides address-based river, creek, storm-tide and overland-flow context.
Page treatment: ask whether symptoms began during or after heavy rain so diagnosis can consider sanitary drainage as well as the visible fixture. Do not attribute a cause without inspection.
