Now, we’re on to the second part of our post. A quick recap: blocked drains are a huge hassle at home and you don’t want them as much as possible. Prevention is the key; hence, we have listed some of the most common reasons that cause blocked drains. Let’s continue, shall we?


Baby wipes, tampons, sanitary pads and tissues shouldn’t go down the drain, regardless of what you’re told. Flushing these toiletries down the drain is a guarantee you’ll face blockages soon.

So instead of flushing down these toiletries, have a rubbish bin nearby and throw everything there. Empty them out at the end of every day or week. Moreover, if you have children at home, teach them how to dispose of them properly.

In the unfortunate situation that you’re already dealing with blocked drains because of toiletries, the first and easiest thing to use is a plunger. Run hot water to soften the blockage, pour in some dishwashing liquid and then wash with more hot water afterwards.

Tree Roots

In Australia, tree roots are a common cause of blocked drains. This is because most houses have large trees in their yard. Yes, these trees are beneficial and beautiful, but the roots can easily find a hairline crack or break in a sewer drain and eventually, they’ll reach the drain.

The best prevention here is to have regular plumbing maintenance. A plumber can check the sewer pipes to ensure that they work and are in good shape.

When tree roots have already invaded your sewer pipes and are causing blocked drains, leave it to the experts. Plumbers have power tools that can unclog these drains easily.

Twigs and Leaves

Leaves and twigs can build up, and they can eventually find their way to your stormwater drains. When you don’t remove them, they will cause blocked drains at home. An effective way to prevent this is to install a gutter guard. Also, make sure to clean your roof gutters regularly—which is at least four times a year, especially in the summer.

Finally, be mindful of wild birds and possums that frequently pass by because they may carry plant seeds that could end up on your roof.

Heavy Rain and Storms

Sometimes, rainwater can overwhelm drains. Torrential rains can make it challenging for water to get away quickly and may block the drains. In turn, they may cause floods that could lead to property damage.

Prevent this by sealing cracks in your foundation and have a plumbing inspection of your sewers and stormwater drains regularly. It’s best to do it before the rainy season arrives so you’re well-prepared. After all, the weather in Adelaide can get unpredictable and the rain could be so strong!

Broken Pipes

Broken pipes can also cause blocked drains. So if you live in an old house, you should be more mindful of the plumbing and ensure it’s up-to-date. Also, keep a lookout for greener patches in your garden because they may indicate a leak.


And that’s it! Now that you know the common reasons for blocked drains, you can prevent them easily. Still, nothing beats regular plumbing inspections to avoid plumbing issues in the future.
