5 Common Causes of Blocked Drains and How to Prevent Them

Posted by Perth Blocked Drains Plumbing on 9 Jan 2026

Blocked drains are an inconvenience which can cause a disruption in your daily life. They can lead to flooding, bad smells, and even health hazards. If they’re not treated promptly blocked drains may cause serious issues in the plumbing system, which could lead to expensive maintenance or repairs.

Key Takeaways

  • Blocked drains can disrupt your day-to-day routine and result in problems with water, bad smells, and even health risks.
  • The fat, oil and grease accumulations can stick to the pipes’ walls, causing obstructions; try not to pour grease down the drain, or use soap and hot water for cleaning dishes.
  • Tree roots naturally extend into the ground searching for nutrients that could cause severe damage to pipes and even completely block them leading to flooding; regularly maintain the trees surrounding drainage systems by trimming them.
  • Wet towels, wipes and sanitary pads and so on. can result in nasty smells emanating from toilets or bins. just wash toilet papers down drain.
  • Hair

In this post, we’ll explore five causes of blocked drains and ways to avoid them.

Cause 1. Grease, oil and Fat buildup

Fat, grease and oil may appear like harmless materials to dump down the drain however, over time, they begin to accumulate over the insides of pipes, causing the pipes to become blocked. As a result it is impossible for water to move freely through the drainpipes. The best solution is to refrain from the practice of pouring grease into the drain. Alternatively, use hot water and soap while cleaning dishes, as this helps break down greasy substances.

Cause 2. Tree Roots

In time, the tree roots naturally expand into the soil in search of nutrients, which means that they grow towards underground pipes. Once they are inside the pipes, tree roots can cause massive damage and could completely block them leading to flooding. It’s crucial, therefore, if you are near trees to maintain the growth of your trees around drainage systems by trimming the trees regularly.

Cause 3: Flushed items

It’s not difficult to conclude that flushing non-biodegradable things like wet towels, sanitary wipes etc. won’t cause any significant problems in the end, however, if too many of these products are flushed into toilets, they can pile up and push others away, blocking pipes – this can cause a bad smell to be released in the vicinity of toilets or bins! Always be aware of what should be flushed, and what shouldn’t (i. the only toilet paper is to be flushed out).

Cause 4 Hair
