Blocked Sewer & Stormwater Adelaide
A blocked sewer or stormwater line is one of the most urgent plumbing problems a home can face — overflowing gullies, gurgling toilets and sewage backing up inside. We clear main lines fast and, just as importantly, find out why it happened.
Blocked stormwater causes flooding and undermines foundations during Adelaide's heavy downpours, while sewer blockages create genuine health hazards. We clear, camera and permanently repair both.

What we do
Main line clearing
Powerful jetting and electric machines clear even stubborn sewer and stormwater blockages back to full flow.
Root cause diagnosis
A camera inspection reveals whether roots, collapse, grease or debris caused it — so it's fixed once, not monthly.
Lasting repairs
Where a pipe is damaged, we reline or replace the affected section and back eligible work with our 20-Year Workmanship Warranty*.

Common questions
Why do my drains keep blocking?
Recurring blockages almost always point to an underlying cause rather than a one-off clog. The most common culprits in Adelaide homes are tree roots entering pipe joints, a build-up of fat and grease, or a partial pipe collapse or misalignment.
Read the full guideCan tree roots break sewer pipes?
Yes — tree roots are one of the leading causes of sewer damage. Roots seek out moisture and nutrients and enter through tiny cracks or joints, then expand as they grow, eventually cracking or blocking the pipe.

A drain snake (electric eel) punches a hole through a blockage, which is great for a quick clear but leaves grease and debris clinging to the pipe walls. Hydro jetting uses high-pressure water to scour the entire inside of the pipe, removing roots, grease and sludge.
