Blocked Drain Melbourne: The Complete Guide (Causes, Costs & Solutions)

Why Blocked Drains Are So Common in Melbourne

Melbourne's south-east suburbs have some of the oldest sewer and stormwater infrastructure in Victoria. Suburbs like Oakleigh, Caulfield, Brighton, Bentleigh, Murrumbeena, and Carnegie were largely developed in the mid-20th century when clay and concrete pipes were standard. Fifty years later those pipes are deteriorating — and Melbourne's established tree canopy means root intrusion is endemic. Add in the cooking fats, wet wipes, and general debris that accumulate in household drains and it's no surprise blocked drains are one of our most common call types.

The Most Common Causes

Tree root intrusion is the leading cause of recurring blocked drains in Melbourne's older suburbs. Roots enter through joint separations in clay pipes and grow until the pipe is obstructed. Fat, oil, and grease accumulate on pipe walls over time, narrowing the diameter until even small debris causes a blockage. Foreign objects — wet wipes, cotton buds, sanitary products, children's toys — cause toilet blockages. Despite labelling, no wet wipe breaks down in sewers the way toilet paper does. Structural pipe failure (collapsed sections, joint separations, pipe bellying) creates zones where waste accumulates repeatedly.

What a Plumber Actually Does

High-pressure water jetting is the professional standard for clearing blocked drains. Water is blasted through the pipe at up to 5000 PSI, cutting through root masses, grease, and debris. It's more effective than electric eels for most blockages and safer for older pipes. CCTV drain inspection follows for any recurring or unexplained blockage — a camera fed through the drain shows exactly what's causing the problem. Pipe relining is the permanent solution for structural damage: a resin liner inserted and cured inside the pipe creates a seamless, root-resistant pipe without excavation.

What Does It Cost?

A straightforward blocked drain cleared with high-pressure jetting: $200–$450 depending on access and severity. CCTV inspection: $150–$300, often combined with jetting on the same visit. Pipe relining costs depend on pipe diameter and length — a CCTV assessment is required before accurate quoting. ATC Plumbing provides upfront pricing before starting any work.
