Common Causes and Prevention of Blocked Drains

A blocked drain can be the worst possible scenario for a homeowner. The inconvenient pooling of water, the unpleasant odour, and potential sanitary concerns are issues none of us want to deal with. Understanding what causes blocked drains is the first step to preventing them. In this guide, we delve into the common causes of drain blockages and provide insightful tips for prevention, ensuring your drainage system remains in top-notch condition.

1. Hair Build-up

Cause: One of the leading causes of blocked drains in bathrooms is the accumulation of hair. Over time, hair strands can bind with grease and other sticky substances, leading to clogs.

Prevention: Invest in drain guards or hair catchers for your showers and sinks. These tools trap hair before it goes down the drain, making it easy to dispose of appropriately. Regularly clean these guards to maintain optimal water flow.

2. Grease and Fat

Cause: Kitchen sinks frequently suffer from blockages due to the accumulation of grease and fat. When washed down the sink, these substances can solidify and stick to pipe walls, restricting water flow.

Prevention: Never pour grease or fat down the drain. Instead, let it cool and solidify, then scrape it into a bin. For added protection, regularly flush your drains with boiling water or a mixture of vinegar and baking soda to break down any potential build-ups.

3. Foreign Objects

Cause: Objects like soap, toys, toiletries, and even food particles can get lodged in pipes and cause blockages, especially if they’re not designed to be flushed or washed down drains.

Prevention: Educate family members, especially children, about what can and cannot go down the toilet or sink. Install strainers over drains to catch larger debris.

4. Tree Roots

Cause: Australia’s diverse flora means tree roots can often infiltrate outdoor pipes in search of water. These roots can cause extensive damage and severe blockages.

Prevention: Regularly check areas of your yard where trees and shrubs are near plumbing lines. Consider root barriers or redirecting your drainage system if vegetation is close. Professional services like Swell Irrigation can assess and guide homeowners on the best preventive measures.

5. Mineral Build-up

Cause: Hard water can lead to mineral build-up in your pipes. Over time, these deposits can restrict water flow and result in blockages.

Prevention: Consider installing a water softener for your home. If you notice early signs of mineral build-up, descaling agents can help clear minor blockages.

6. Toilet Paper and Sanitary Products

Cause: Excessive use of toilet paper, flushing of non-biodegradable wipes, and disposal of sanitary products down the toilet can lead to significant blockages.

Prevention: Only flush small amounts of toilet paper at a time. Avoid flushing wipes, even if labelled “flushable”, and provide appropriate disposal methods for sanitary products.

7. Collapsed Pipes

Cause: Old, corroded, or poorly-installed pipes can collapse, leading to severe drainage issues. This problem is more prevalent in older Australian homes with outdated plumbing.

Prevention: Regular plumbing checks can identify potential weak spots in your drainage system. If your home is older or you’ve noticed consistent drainage issues, consulting with experts like Swell Irrigation can help assess the condition of your pipes.

8. Accumulation of Soap and Detergents

Cause: Soap, combined with minerals present in water, can form soap scum, which can cling to the sides of pipes and cause blockages.

Prevention: Regularly flush your pipes with hot water. Opt for soap-free washes or liquid soaps that are less likely to leave residues.

9. Kitchen Waste and Coffee Grounds

Cause: Many homeowners have a habit of disposing of kitchen waste, especially coffee grounds, down the sink. Over time, these can accumulate and create stubborn blockages.

Prevention: Use a compost bin for organic kitchen waste. For coffee grounds, instead of sending them down the drain, consider adding them to your compost pile, garden soil, or disposing of them with solid waste.

10. Build-up of Dirt and Debris

Cause: Dirt from soiled clothes, mud from cleaning tools or outdoor equipment, and general debris can accumulate in drains, leading to potential blockages.

Prevention: Before washing, shake out excess dirt or mud from clothes outside. For heavy soiled items, consider pre-rinsing or cleaning them outdoors. Regularly clean external drain grates from leaves and other debris to ensure clear water passage.

11. Heavy Rain and Storms

Cause: Particularly in Australia, where heavy rains can come suddenly, stormwater can overwhelm systems, leading to blocked external drains.

Prevention: Ensure your external drains and gutters are clear of debris. Installing a rainwater tank can help capture excess water, reducing the load on your drainage system. Regularly check and clean your gutters to prevent blockages from leaves, twigs, and other debris.

12. Rust and Pipe Erosion

Cause: Over time, internal pipe surfaces can corrode and rust, causing particles to fall off and block the drain.

Prevention: Regular pipe maintenance and checking for early signs of corrosion can help. If you notice rusty-coloured water or reduced water pressure, it might be time to consult with plumbing professionals. Consider upgrading to rust-resistant pipes if you live in an area with hard or mineral-rich water.

Delving Deeper: Long-term Preventive Strategies:

• Awareness and Education: Make sure everyone in the household understands what can and cannot be disposed of down the drain. Simple awareness can prevent many potential blockages.
• Regular Inspections: Consider CCTV drain inspections, offered by professionals like Swell Irrigation, to get a clear picture of the internal condition of your pipes, helping to spot potential blockages or areas of worry before they develop into substantial problems.
• Invest in Quality: When installing new plumbing systems or replacing old ones, investing in quality pipes and fixtures can save you from future hassles. Often, upfront investments can lead to long-term savings.
• Stay Updated: As with many fields, plumbing and drainage solutions are evolving. Newer, eco-friendly solutions can prevent blockages and reduce the environmental impact. Stay updated with the latest in plumbing solutions and consider upgrades when feasible.

In conclusion, blocked drains can be a hassle, but with a bit of knowledge and proactive measures, many common causes can be prevented. Regular maintenance, both self-conducted and by professionals like Swell Irrigation, ensures that your home’s plumbing remains unobstructed and efficient. Keep in mind that prevention is always preferable than treatment and is frequently less expensive.
