What Causes Blocked Drains? Warning Signs Melbourne Homeowners Should Know
What Causes a Blocked Drain?
Blockages build up gradually as material accumulates inside your pipes and restricts water flow. The cause is often different depending on where the blockage is.
Blocked Kitchen Sink Causes
In kitchens, grease, cooking oils, food scraps, and coffee grounds are the most common culprits behind a blocked kitchen sink. Poured down the drain while hot, fats and oils cool and solidify inside the pipe, gradually narrowing it until water can no longer pass through.
Blocked Bathroom & Shower Drain Causes
A blocked shower drain or blocked bathroom drain is usually caused by a build-up of hair, soap scum, and hygiene products. These bind together inside the pipe over time, slowing drainage until the shower or sink stops draining altogether.
Blocked Toilet Causes
A blocked toilet is most often caused by flushing non-flushable items wet wipes, sanitary products, or excess toilet paper that don’t break down the way standard toilet paper does, creating an obstruction further down the pipe.
Tree Root Blocked Drains
Tree root intrusion is one of the most serious causes of a blocked drain, particularly in older Melbourne suburbs with ageing clay pipes. Roots seek out moisture and can grow into tiny cracks or joints in underground pipework, eventually causing a complete blockage or pipe collapse.
Outdoor & Stormwater Drain Blockages
Leaves, dirt, and debris commonly block outdoor and stormwater drains, especially during heavy rain. Left unaddressed, this can cause water pooling around your property and increase the risk of flooding during storms.
Warning Signs of a Blocked Drain
Drain blockages rarely happen without warning. Catching these signs early can prevent a minor clog from becoming a costly emergency.
Water draining slowly from sinks, showers, or bathtubs
Gurgling noises coming from drains or toilets
Unpleasant odours near drains or plumbing fixtures
Water pooling around floor drains or outdoor grates
Frequent toilet backups or overflow issues
Multiple drains becoming slow at the same time
A clogged drain that keeps recurring despite previous cleaning attempts
Why a Recurring Blocked Drain Needs Professional Attention
If a blockage keeps coming back despite repeated clearing attempts, it usually means there’s a deeper issue damaged pipes, tree root intrusion, pipe misalignment, or an ageing drainage system. Repeatedly using chemical drain cleaners on a recurring clogged drain can actually damage your pipes further and make the underlying problem worse over time.
How CCTV Drain Inspection Finds the Real Cause
A CCTV drain inspection uses a waterproof camera to look inside your pipes in real time, allowing a plumber to pinpoint the exact location and cause of a blockage whether that’s tree roots, a collapsed section, or built-up debris without unnecessary digging or guesswork.
High-Pressure Drain Jetting
For stubborn blockages, high-pressure drain jetting blasts water through the pipe at force, clearing grease, sludge, roots, and debris far more effectively than a standard drain snake, while also flushing the pipe clean.

Frequently Asked Questions About Blocked Drains
What is the most common cause of blocked drains?
Grease build-up, food waste, hair, soap residue, and tree root intrusion are among the most common causes of blocked drains in Melbourne homes.
Can blocked drains cause property damage?
Yes. An untreated blockage can lead to overflowing fixtures, sewage backups, and water damage to floors, walls, and cabinetry if left unresolved.
Are chemical drain cleaners safe to use?
Not always. Repeated use of chemical drain cleaners can corrode pipes over time, particularly older pipework, and often only clears the surface of a blockage rather than the underlying cause.
How do plumbers find the cause of a blocked drain?
Plumbers use CCTV drain cameras to inspect inside the pipe and visually identify the exact location and cause of the blockage, whether that’s tree roots, debris, or a damaged pipe.
When should I call a plumber for a blocked drain?
If a blockage keeps recurring, affects multiple drains at once, or doesn’t clear with basic household methods, it’s best to call a licensed plumber for a proper inspection before the problem worsens.
