Blocked drains are a common plumbing issue that can cause significant inconvenience and potentially expensive repairs. Understanding the primary causes of blocked drains and taking preventive measures can help you avoid these problems altogether. In this article, we will explore the most frequent culprits behind blocked drains and provide effective strategies to prevent them from occurring.
1. Hair and Soap Scum:
Hair and soap scum are major contributors to blocked drains, especially in bathrooms and showers. As you shower or wash your hair, strands of hair and soap residue often accumulate in the drainpipe over time, causing a blockage. To prevent this:
– Install drain guards or hair catchers: These inexpensive devices fit over the drain, capturing hair and preventing it from entering the pipes.
– Regularly clean the drain guards: Remove accumulated hair and debris from the drain guards after each shower or as needed.
2. Food Waste:
Kitchen sinks are prone to blockages caused by food waste. Grease, oil, coffee grounds, and food scraps often find their way down the drain, leading to clogs. To prevent this:
– Avoid pouring cooking oil or grease down the sink: Instead, let it solidify and dispose of it in the trash.
– Use sink strainers: Place a sink strainer over the drain to catch food particles and prevent them from entering the pipes.
– Scrape dishes before washing: Dispose of food scraps in the trash or compost bin before rinsing dishes to minimise the amount of food waste going down the drain.
3. Tree Roots:
In outdoor drains and sewer lines, tree roots can be a significant cause of blockages. Over time, roots can invade the pipes, causing them to crack or collapse. To prevent tree root-related blockages:
– Plant trees away from drainage systems: Be mindful of the location of your trees and avoid planting them near underground pipes or drainage systems.
– Regularly maintain trees and shrubs: Prune the roots of trees and shrubs near your drainage system to minimise the risk of infiltration.
4. Foreign Objects:
Foreign objects, such as sanitary products, wipes, cotton balls, and paper towels, are often flushed down toilets or washed down sinks, leading to blockages. To prevent this:
– Educate household members: Teach everyone in your household about what can and cannot be flushed or washed down the drain.
– Provide proper waste disposal options: Place clearly labelled waste bins in bathrooms to encourage the disposal of items like wipes and sanitary products in the trash.
5. Insufficient Pipe Slope:
Incorrect pipe installation or gradual settling of the ground can result in an insufficient slope in the drainage system. This can impede the proper flow of water and lead to blockages. To prevent this:
– Hire a professional plumber: Ensure that your drainage system is installed correctly by hiring a qualified plumber who understands the importance of proper pipe slope.
– Regular maintenance: Schedule periodic inspections of your drainage system to identify and address any issues promptly.
Conclusion:
By understanding the common causes of blocked drains and implementing preventive measures, you can significantly reduce the likelihood of encountering drainage issues. Remember to practice good drain maintenance habits, educate household members, and seek professional assistance when necessary. Taking these proactive steps will help keep your drains clear and your plumbing system running smoothly.
