Blocked-drain warning signs
One slow fixture may be a local restriction. Several fixtures slowing, gurgling or backing up together points to a larger drainage problem that needs a plumber.
Safety classification
Safe inspection only
This guide covers safe first actions only. It is not a licence to perform regulated work or enter a dangerous area.
What to do
- 1
Compare affected fixtures
Note whether the issue affects one basin or toilets, showers and floor wastes across the property.
- 2
Listen and smell
Gurgling after another fixture drains and recurring sewer odours are useful clues.
- 3
Look outside from ground level
Check for unusually wet ground or overflowing inspection points without opening covers or entering wastewater.
- 4
Reduce water use
Stop running dishwashers, washing machines and unnecessary taps until the line is assessed.
- 5
Prepare the request
List every affected fixture, when it started and any recent digging, storms or repeat blockages.
When to stop
