What it could mean
Understand the symptoms.
A blocked private line and a network blockage have different repair responsibilities.
What to do next
Sydney Water advises that several affected properties or ongoing overflow without household water use can indicate its network; call 13 20 90 for advice.
When a plumber should assess it
If the fault continues, is affecting other fixtures, risks damage or cannot be identified safely, arrange a professional assessment. Similar symptoms can have different causes, so an inspection is needed before confirming a repair.
What to tell us
- Your suburb and the affected fixture or system
- Whether the problem is continuous or intermittent
- Any noises, visible leaks, odours or recent changes
- Whether it involves a single fixture or several
