Which drains are affected?
A blockage affecting one sink differs from a problem affecting several fixtures. Note whether the shower, toilet or outdoor drain also backs up when water runs elsewhere. These details help describe the extent of the problem.
If a toilet bowl is rising, stop flushing. If sewage is visible, stop using the affected plumbing and keep people and pets away from it.
- Kitchen sinks draining slowly or holding water.
- Showers and bathroom drains backing up.
- Toilets that will not drain after flushing.
- Outdoor drains overflowing during or after rain.
Why does the blockage keep returning?
A recurring blockage needs its cause assessed, rather than judged by how quickly the water eventually disappears. The location, pipe condition and material in the drain affect the next step. Tell us about previous clearing work and how long the improvement lasted.
Inspection and clearing methods depend on the drain and access. Ask what is proposed, what it will establish and whether further pipe repairs would be a separate job.
Private drain or water authority problem?
Responsibility depends on where the fault sits. Yarra Valley Water's repair-responsibility guide explains the distinction for its customers. Contact your own water authority if a public sewer fault is suspected; shared and private connections need particular care.
Common questions
Does a running toilet mean the drain is blocked?
A cistern that keeps filling usually needs its flush or inlet mechanism checked. A bowl that holds or rises with wastewater points to a drainage problem. Tell us which is happening.
What affects the cost of clearing a drain?
The blockage location, access, investigation needed and whether pipe damage is found all affect the scope. Ask about assessment charges and the proposed work before agreeing to proceed.
