Blocked drains are a common household issue that can lead to inconvenience, unpleasant odors, and potential damage to your plumbing system. In Melbourne, where the weather can be unpredictable and the infrastructure varies, understanding the common causes of blocked drains in Melbourne is crucial. This article will explore the 10 most frequent culprits and provide tips on how to avoid them to keep your drains flowing smoothly.

Hair Build-Up:

Hair is one of the leading causes of blocked drains. In Melbourne, with its diverse population and varied hair types, it’s essential to use drain guards in your shower and bathroom sinks. Regularly cleaning these guards can prevent hair from accumulating and causing blockages.

Grease and Oil:

Cooking oils and grease are notorious for clogging drains. In the colder months in Melbourne, these substances can solidify more quickly, leading to blockages. Dispose of grease in a separate container and avoid pouring it down the sink. Wipe greasy dishes with paper towels before washing to minimise oil entering the drain.

Foreign Objects:

Melbourne, being a bustling city, often sees drains clogged by foreign objects such as toys, sanitary products, and even small household items. Educate your household members about what should and shouldn’t be flushed or disposed of in sinks, toilets, or drains.

Tree Roots:

Melbourne’s greenery is a source of pride, but it can also be a cause of blocked drains. Tree roots can invade pipes, especially in older neighborhoods. Regularly inspect and maintain your outdoor pipes, and consider planting trees away from your plumbing infrastructure.

Soap Scum:

Soap scum can accumulate over time, creating a thick layer that obstructs water flow. Opt for liquid soap instead of bar soap, as it produces less scum. Periodically clean your drains with a mixture of vinegar and baking soda to break down soap scum.

Mineral Build-Up:

Melbourne’s water supply contains minerals that can accumulate in pipes, leading to blockages. Install water softeners if necessary and use drain-cleaning solutions regularly to prevent mineral build-up.

Collapsed Pipes:

Melbourne’s diverse terrain and aging infrastructure can result in collapsed pipes. If you notice consistent blockages or slow drainage, seek professional assistance to inspect your pipes and address any structural issues.

Excessive Toilet Paper:

While toilet paper is designed to break down easily, using an excessive amount can lead to blockages. Educate your household about the proper amount of toilet paper to use, and consider using single-ply options.

Poor Drain Slope:

The slope of your drains is critical for proper water flow. In Melbourne, where heavy rains are not uncommon, ensure that your drains are properly sloped to prevent water pooling and potential blockages.

Lack of Regular Maintenance:

Neglecting regular drain maintenance is a common reason for blockages. Schedule routine inspections, cleanings, and maintenance to catch potential issues before they escalate.


Blocked drains can be a significant inconvenience, but by understanding and addressing the common causes, you can avoid most issues. In Melbourne, where the climate and infrastructure pose unique challenges, proactive measures and regular maintenance are key. By following these tips, you can keep your drains in Melbourne flowing freely, ensuring a hassle-free plumbing system for your home.
