Blocked Drains Melbourne: 7 Warning Signs You Should Never Ignore
A blocked drain might start as a slow sink or an unpleasant smell, but if left untreated, it can quickly become a major plumbing emergency.
At Ivanhoe Plumbing & Gas, we specialise in diagnosing and clearing blocked drains for homes, businesses and strata properties across Melbourne's north-eastern suburbs. Using high-pressure water jetting and CCTV drain inspections, we don't just clear the blockage—we identify the cause to help prevent it from happening again.
Here's what every property owner should know about blocked drains.
1. Water Is Draining Slowly
One of the first signs of a developing blockage is water taking longer than usual to drain from:
Kitchen sinks
Bathroom basins
Showers
Bathtubs
Laundry tubs
Floor wastes
Slow drainage often indicates a build-up of grease, soap residue, food waste, hair or tree roots within the pipework.
2. Gurgling Noises from Drains
If you hear bubbling or gurgling sounds after flushing a toilet or using a sink, it could indicate trapped air caused by a restriction in the drainage system.
These noises often appear before a complete blockage develops.
3. Unpleasant Odours Around Your Property
Bad smells coming from:
Floor drains
Kitchen sinks
Bathroom drains
Inspection openings
External sewer vents
can indicate a partially blocked sewer or a build-up of organic waste inside your drainage system.
Ignoring these odours can allow the blockage to worsen over time.
4. Toilets That Flush Poorly
If your toilet:
Flushes slowly
Requires multiple flushes
Frequently backs up
Has rising water levels
it may indicate a blockage within the sewer line rather than a fault with the toilet itself.
Professional inspection is recommended before the issue escalates.
5. Multiple Fixtures Blocking at Once
When several fixtures are affected simultaneously, such as:
Toilet
Shower
Basin
Laundry
the problem is often located within the property's main sewer line.
This type of blockage typically requires professional equipment to diagnose and clear.
6. Water Overflowing Outside
Overflowing inspection openings, boundary traps or external drains are strong indicators of a significant sewer blockage.
This should be addressed promptly to prevent:
Property damage
Health hazards
Sewage overflow
Damage to landscaping
7. Tree Roots in Sewer Pipes
Tree roots are one of the most common causes of blocked drains throughout Melbourne.
Roots naturally seek moisture and can enter drainage systems through:
Cracked pipes
Loose joints
Broken earthenware drains
Ageing sewer infrastructure
Once inside the pipe, roots continue growing and trap toilet paper, grease and other debris until a complete blockage occurs.
What Causes Blocked Drains?
Some of the most common causes include:
Tree root intrusion
Grease and fat build-up
Wet wipes
Sanitary products
Foreign objects
Hair accumulation
Collapsed pipes
Pipe misalignment
Ageing earthenware drains
Stormwater debris
Scale build-up
Damaged sewer pipes
How We Clear Blocked Drains

Our blocked drain services include:
High-Pressure Water Jetting
Our commercial-grade jetting equipment removes:
Tree roots
Grease
Fat deposits

Cracks
Collapsed sections
Pipe offsets
Poor previous repairs
Corrosion
Foreign objects
A camera inspection allows us to recommend the most cost-effective long-term solution rather than simply treating the symptoms.
