Arncliffe has changed a lot. Older semis, cottages and walk-up flats still fill many streets near the station, while newer apartment buildings have gone up along the Princes Highway and towards Wolli Creek. Underneath, the drainage is just as mixed, and so are the blockages. St George Blocked Drains is a local referral service. We connect Arncliffe residents, landlords and strata managers with licensed local drain plumbers we work with.
Why Arncliffe drains block
Age is a big part of it. Arncliffe is one of the older suburbs in the region, and plenty of homes still drain through original earthenware or early concrete pipes. Those lines crack and separate at the joints over time, roots get in, and blockages keep coming back.
Low-lying ground adds to it. Parts of Arncliffe sit low near the Cooks River and Muddy Creek, where groundwater is closer to the surface and stormwater has less fall to work with. Flat pipe runs collect sediment, and in heavy rain a partly blocked stormwater system struggles quickly.
Then there is density. Walk-up flats and apartment buildings share sewer lines between many households. Wet wipes, grease and food waste from a dozen kitchens build up in a shared line long before anyone notices, and a blockage there affects every unit upstream of it.
What clearing a blocked drain involves
The licensed plumbers we work with locate the blockage, clear it with an eel or jet blasting, and use a CCTV drain camera to show the cause. For strata properties the footage is useful when deciding whether a blockage sits in common property or a single lot's pipework. If a whole building is backing up, treat it as one of the emergency blocked drains and say so when you enquire.
As a guide, a standard clear typically costs $150 to $400, root clearing $250 to $600, a camera inspection $249 to $600, and camera with jetting $350 to $900. Relining typically costs $3,000 to $8,000 or more. You get the price before any work starts.
Frequently asked questions
I live in a unit and the shower drain is backing up. Who do I call?
Let your strata manager or landlord know, as the shared line is usually common property. You can still request a quote here, and the plumber can confirm where the blockage sits.
Our semi shares a sewer line with next door. Who pays to clear it?
Shared private lines are usually the joint responsibility of the properties they serve. A camera inspection shows where the blockage is, which helps settle it fairly.
Does flooding near the Cooks River affect my drains?
Low-lying properties drain more slowly and can see stormwater back up in heavy rain. Keeping pits and pipes clear gives the system the best chance.
