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. 1

    Compare affected fixtures

    Note whether the issue affects one basin or toilets, showers and floor wastes across the property.

  2. 2

    Listen and smell

    Gurgling after another fixture drains and recurring sewer odours are useful clues.

  3. 3

    Look outside from ground level

    Check for unusually wet ground or overflowing inspection points without opening covers or entering wastewater.

  4. 4

    Reduce water use

    Stop running dishwashers, washing machines and unnecessary taps until the line is assessed.

  5. 5

    Prepare the request

    List every affected fixture, when it started and any recent digging, storms or repeat blockages.

When to stop

  • Sewage is overflowing
  • Water is near electricity
  • The blockage affects the whole property
  • Chemical drain cleaner has already been used
