Wolli Creek has changed more than almost any suburb in St George. Former industrial land around Wolli Creek station, where Wolli Creek meets the Cooks River, is now dense with apartment towers, and most residents live in strata buildings rather than freestanding houses. That changes what a blocked drain looks like. St George Blocked Drains is a local referral service that connects Wolli Creek residents, owners and strata managers with licensed local drain plumbers we work with.
Why Wolli Creek drains block
In apartment buildings, most blockages start inside the unit. Kitchen sinks clog with fat, oil and food scraps, bathroom basins and showers with hair and soap, and toilets with wipes. Because units are compact and often have long horizontal runs from the kitchen to the building stack, a small build-up can stop a sink completely.
Shared drainage is the next layer. Many units connect into common stacks and pipes that serve several floors. When a shared line blocks, the lowest apartments on that stack are usually the first to see water backing up, even though the waste came from upstairs.
The ground itself is a factor. Wolli Creek is low-lying, near the river and creek, and buildings here often have basement car parks with pits and pumps that move stormwater and seepage out. A pump that fails or a pit that silts up can flood a basement quickly in heavy rain.
What clearing a blocked drain involves
For a single unit, the licensed drain plumbers we work with usually clear the fixture and the branch line, then check the connection to the stack. For shared lines, a CCTV drain camera shows where the blockage sits and which section of pipe belongs to whom. Jet blasting clears grease from kitchen lines and common pipes. A blocked toilet is often a single visit.
What it costs
A standard clear typically runs $150 to $400. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. Root clearing, which is less common in newer buildings, typically runs $250 to $600. If a damaged pipe needs relining, expect $3,000 to $8,000 or more. Every plumber quotes before work starts.
Frequently asked questions
Is a blocked drain in my unit my problem or the strata's?
It depends on where the blockage sits. Fixtures and pipes serving only your unit are often the owner's responsibility, while common stacks usually fall to the owners corporation. Check your strata by-laws, and a camera report helps settle it.
Water is coming up through my shower but I did not cause it. Why?
That often means a blocked shared stack, with waste from units above backing up at the lowest point. Tell your strata manager and see our emergency blocked drains page.
Can a plumber help with a flooded basement car park?
Yes. Plumbers can clear silted pits and stormwater lines and check whether the pump is working. Your strata manager will usually need to approve the work.
