Common Symptoms
Water draining slowly in sinks, showers or basins
A gradual slow-down in drainage is the earliest sign of a developing blockage. You may notice water pooling around your feet in the shower or taking minutes to empty from the kitchen sink. This usually indicates a partial obstruction — grease buildup, soap scum, or hair accumulating inside the pipe — that will worsen if left untreated.
Gurgling sounds from drains or toilets
Gurgling or bubbling noises when water drains — or when a nearby fixture is used — indicate trapped air being displaced by water trying to pass a blockage. If your toilet gurgles when you run the bathroom sink, the obstruction is likely in a shared waste line further downstream.
Foul odours coming from drains or gully traps
Persistent bad smells from floor drains, sink plugholes, or outdoor gully traps suggest organic matter is decomposing inside the pipe. Food waste, grease, and sewage trapped behind a blockage produce hydrogen sulphide gas — the characteristic ‘rotten egg’ smell that indicates the drain needs clearing.
Water backing up into other fixtures
When flushing a toilet causes water to rise in the shower, or running the washing machine sends water out through the laundry floor drain, you have a blockage in a shared sewer line. This cross-contamination between fixtures is a clear sign of a serious obstruction that needs prompt professional attention.
Overflowing gully trap or inspection point
If the gully trap outside your home (the small grated drain near the kitchen or laundry) is overflowing with wastewater, the blockage is in the underground sewer line between your house and the main sewer. This requires professional equipment — typically a drain machine or high-pressure water jetter — to clear.

Common Causes
Tree root intrusion
Tree roots are the most common cause of blocked drains in Melbourne. Roots seek moisture and nutrients, penetrating even small cracks or displaced joints in clay, PVC, and earthenware pipes. Once inside, they form a dense root mass that catches debris and progressively blocks the pipe. Older suburbs with established trees and original clay drains are especially susceptible.
Grease, fat, and oil buildup
Cooking fats poured down the kitchen sink solidify as they cool, coating the inside of pipes and gradually narrowing the bore. Over months and years, this grease layer traps food particles and other debris, creating stubborn blockages that household drain cleaners rarely resolve. Commercial kitchens and share-houses are particularly prone.
Foreign objects and non-flushable items
Wet wipes (including those labelled ‘flushable’), sanitary products, cotton buds, nappies, and excessive toilet paper are frequent culprits in blocked sewer lines. These items don’t break down in water the way toilet paper does and can snag on pipe joints or existing buildup, creating a blockage that requires mechanical clearing.
Broken, collapsed, or misaligned pipes
Ground movement from Melbourne’s reactive clay soils, age-related deterioration, or damage from construction can crack, collapse, or displace underground drain pipes. A broken pipe creates a rough surface that catches debris and restricts flow. In severe cases, the pipe collapses entirely and must be replaced or relined.
Hair and soap scum accumulation
In bathrooms, hair combines with soap residue to form dense clumps that lodge in the drain trap and waste pipe. Over time, these clumps grow and harden, significantly reducing water flow. Showers and bathtub drains are most affected, especially in households with multiple occupants or long-haired residents.

Prevention Tips
Use drain strainers in all sinks and showers
Inexpensive mesh or silicone drain strainers catch hair, food scraps, and debris before they enter the pipe. Clean them after each use. This single habit prevents the majority of household drain blockages and costs almost nothing compared to a plumber call-out.
Never pour grease or oil down the drain
Let cooking fats cool and solidify, then scrape them into the bin. Wipe greasy pans with paper towel before washing. For large volumes of oil (e.g. from a deep fryer), pour into a sealed container and dispose of it at your local recycling centre. Even small amounts of grease accumulate over time.
Only flush toilet paper
Toilets are designed for human waste and toilet paper only. Wet wipes, cotton pads, sanitary items, and dental floss should always go in the bin. Even products marketed as ‘flushable’ can contribute to blockages, particularly in older plumbing systems with narrower pipes or displaced joints.
Manage vegetation near sewer lines
Know where your underground sewer and stormwater lines run and avoid planting large trees directly above or beside them. If established trees are already near your drains, consider a periodic CCTV drain inspection (every 2–3 years) to detect root intrusion early, before it causes a full blockage.
Schedule periodic drain maintenance
For properties with a history of blockages — or those with older clay or earthenware drains — a scheduled maintenance clear every 12–24 months can prevent emergency call-outs. A plumber can jet the line to remove early-stage buildup and inspect pipe condition before problems develop.

Frequently Asked Questions
Got questions? We've got answers. Here are the most common questions we receive from our clients.
Do you do same-day blocked drain callouts?
Yes — when availability allows, we aim for same-day service. Blocked drains that are overflowing or causing sewage backup are treated as urgent and prioritised accordingly.
Will the blockage come back?
It depends on the cause. If the blockage was caused by a one-off event (e.g. a foreign object), it’s unlikely to recur. If tree roots or broken pipes are the underlying issue, the blockage can return unless the pipe is repaired or relined. We’ll tell you what we find and recommend the right long-term fix.
How much does it cost to clear a blocked drain in Melbourne?
The cost varies depending on the location and severity of the blockage, the equipment needed, and whether pipe repairs are required. Simple blockages cleared with a drain machine are at the lower end; complex root intrusions requiring jetting or CCTV inspection cost more. We provide upfront pricing before starting work.
What equipment do you use to clear blocked drains?
We use electric drain machines (drain snakes) for most blockages, high-pressure water jetters for stubborn obstructions like tree roots and grease, and CCTV drain cameras to inspect the pipe condition and pinpoint the exact location and cause of the blockage.
Can I clear a blocked drain myself?
Minor blockages in sink or shower traps can sometimes be cleared with a plunger or by removing and cleaning the trap. However, blockages further down the line — especially in the sewer — require professional equipment. Chemical drain cleaners can damage pipes and are generally not recommended by plumbers.
How do I know if the blockage is in my pipes or the council sewer?
If only one fixture is affected, the blockage is usually in your internal plumbing. If multiple fixtures are backing up or the gully trap is overflowing, the blockage is likely in your sewer line between the house and the property boundary. Beyond the boundary, the sewer main is the water authority’s responsibility — contact your retailer (e.g. Yarra Valley Water, South East Water).
What is CCTV drain inspection?
A small waterproof camera is fed into the drain pipe to provide a live video feed of the pipe’s interior. This allows us to see exactly what’s causing the blockage — roots, cracks, displaced joints, or buildup — and assess the pipe’s overall condition. It’s the most accurate way to diagnose drain problems without excavation.
What is pipe relining and when is it needed?
Pipe relining is a trenchless repair method where a resin-coated liner is inserted into the damaged pipe and cured in place, creating a new pipe inside the old one. It’s used when the pipe has cracks, root damage, or displaced joints but hasn’t fully collapsed. It avoids the cost and disruption of excavating and replacing the pipe.
Do blocked drains cause health risks?
Yes — sewage backups and overflows expose occupants to harmful bacteria and pathogens. Stagnant water can also attract mosquitoes and create mould growth. If sewage is backing up inside your home, avoid contact, ventilate the area, and call a plumber promptly.
Can tree roots damage my drains even if the tree is on a neighbour’s property?
Yes — tree roots don’t respect property boundaries and can travel many metres from the trunk. If a neighbour’s tree is causing blockages in your drains, you’re still responsible for the repairs on your side of the boundary. In some cases, the neighbour may share responsibility for root removal — local council can advise on dispute resolution.
