Blocked drains are one of those problems that seem to appear out of nowhere, yet they can quickly turn into a major headache if left unchecked. Whether it’s a slow-draining sink or an overflowing outdoor drain, understanding the root causes can help you take steps to prevent future blockages.
Let’s break down seven common culprits behind blocked drains, and more importantly, what you can do to avoid them.
1. Hair Build-Up
Hair is one of the biggest offenders when it comes to clogged bathroom drains. Over time, strands of hair collect in your pipes, forming clumps that are difficult to shift. Combine that with soap scum, and you’ve got a recipe for disaster. Regularly clearing hair from your shower or sink drain can go a long way toward keeping things flowing smoothly.
For more stubborn build-ups, you might need to call on plumbing services Adelaide to properly clear out your system.
2. Food Scraps
Even with a kitchen sink strainer, food particles often sneak their way down the drain. Once there, they can cling to grease and other debris, creating a sticky, stubborn blockage. Common culprits include coffee grounds, pasta, and rice, which expand when wet.
To avoid this, scrape plates into the bin before rinsing and never pour leftover oil or grease down the sink—it solidifies as it cools, creating a serious clog.
3. Grease and Fat
Speaking of grease, this is one of the sneakiest causes of blockages. It might seem harmless to pour cooking oils or fats down the drain, but as they cool, they harden and stick to the sides of your pipes.
Over time, this narrows the passageway and eventually leads to a complete blockage. Instead, pour grease into a container, let it cool, and dispose of it in the rubbish. A simple change in routine can save you a world of trouble.
4. Soap Scum
Ever noticed a filmy residue around your shower or sink? That’s soap scum, and while it’s easy to wipe off surfaces, it’s much harder to remove when it accumulates inside your pipes. Traditional soap bars contain fats and minerals that combine with water to form a thick, sticky substance. Over time, this residue builds up, reducing water flow and trapping other debris.
To avoid this, consider switching to liquid soap, which is less likely to leave behind residue.
5. Flushing the Wrong Things
Toilets are designed to handle toilet paper and waste—nothing more. Yet, many people flush items like wet wipes, cotton buds, and sanitary products, thinking they’ll break down like toilet paper. Unfortunately, these items don’t dissolve and can easily block your pipes.
Even “flushable” wipes can cause issues, as they don’t break apart as quickly as you might think. The golden rule? If it’s not toilet paper, it doesn’t belong in the bowl.
6. Tree Roots
If you’re dealing with outdoor drains, tree roots could be to blame. Roots naturally seek out water sources, and your pipes can become an easy target. Once they infiltrate a small crack or join, they’ll grow inside the pipe, causing blockages and potentially serious damage. Regular inspections and maintenance can help you spot this issue before it escalates.
If tree roots are the problem, professional plumbing services will be essential to resolve the issue safely.
7. Foreign Objects
This one might seem obvious, but it’s more common than you’d think. Small toys, jewellery, and even soap bars often find their way into drains, especially in households with children. These objects can lodge themselves in the pipes, creating an obstruction that traps other debris. To avoid this, use drain covers where possible and be mindful of what goes near the sink or bath.
When to Call the Pros
Sometimes, no amount of DIY effort will cut it, and that’s when it’s time to call in the pros. If you’re facing persistent blockages, foul odours, slow-draining water, or even gurgling sounds from your pipes, these are clear signs of a deeper issue.
Professionals have the tools and expertise to tackle tough clogs, whether it’s tree roots, grease build-up, or foreign objects lodged in your pipes. Trying to fix complex problems yourself can sometimes make things worse, so when in doubt, it’s best to leave it to the experts to ensure your plumbing is back in top shape.
Preventing Future Blockages
The good news is that most blocked drains can be prevented with a little extra care. Start by being mindful of what you allow down your drains, whether it’s food, hair, or hygiene products. Installing strainers in your sinks and regularly cleaning your drains can make a huge difference. And if you’re dealing with recurring issues, don’t hesitate to seek professional help to address any underlying problems in your plumbing system.
Blocked drains aren’t just an inconvenience—they can lead to costly repairs if ignored. By understanding these common causes and taking simple preventative steps, you can keep your pipes clear and your household running smoothly.
