Blocked drains are a common issue for both homeowners and businesses. While a blockage can happen for various reasons, understanding the main causes of drain problems can help you prevent them in the future. In this blog, we’ll explore the most common causes of blocked drains, how they affect your plumbing, and what you can do to avoid them.
1. Hair Buildup
One of the most common causes of a blocked drain, particularly in bathrooms, is hair. When you wash your hair in the shower or bath, strands can easily get washed down the drain. Over time, hair can build up and combine with soap, shampoo, and other debris, creating a thick, sticky mass that clogs the pipes. This is especially problematic for older pipes or those with narrow openings.
2. Grease and Fat
Another major cause of blocked drains is grease, fat, and oil. Many people pour leftover cooking oil, fat, or grease down the sink without realising the long-term effects. These substances may be liquid when hot, but as they cool, they harden and form a thick layer inside the pipes. Over time, this can cause a serious blockage, especially in kitchen sinks.
3. Food Waste
While it might seem easy to wash food scraps down the kitchen sink, this can quickly lead to a blockage. Small food particles can get trapped in the pipes, causing gradual build-up over time. Grease, fat, and food waste combined can form a stubborn blockage that’s difficult to clear without professional help. It’s always best to scrape food waste into the bin instead of down the drain.
4. Tree Roots
In some cases, tree roots can be a major cause of blockages in outdoor drains or sewer pipes. As trees grow, their roots naturally seek out water sources, and they can penetrate pipes in search of moisture. Once inside, the roots can block the flow of water, causing significant drainage problems. This is especially true for older or damaged pipes, which can be more susceptible to root intrusion.
5. Foreign Objects
Accidentally flushing or washing non-degradable items down the drain is a frequent cause of blockages. This includes things like wet wipes, sanitary products, cotton buds, paper towels, and even children’s toys. These items do not break down in water and can cause serious blockages, especially in toilets or drains connected to waste systems. It’s important to dispose of these items properly and avoid flushing anything other than toilet paper.
6. Soap Scum and Mineral Buildup
In areas with hard water, mineral deposits can build up in the pipes over time. This can combine with soap scum and other residues to create a sticky layer inside the pipes, which restricts the flow of water. Eventually, this can lead to blockages, especially in bathroom drains. Regular cleaning can help reduce mineral buildup and prevent blockages from occurring.
7. Pipe Damage or Ageing
As pipes age, they can become corroded, cracked, or misaligned. This can cause a blockage by disrupting the normal flow of water. In some cases, the damage can be severe enough to allow debris to accumulate more easily, leading to a gradual build-up of blockages. Regular maintenance and inspections can help identify and fix any pipe issues before they become a serious problem.
How to Prevent Blocked Drains
To avoid blocked drains, it’s essential to be mindful of what goes down your sinks and toilets. Avoid pouring grease, oil, or fat down the drain, and ensure that food waste, hair, and foreign objects are disposed of correctly. Regularly cleaning your drains and scheduling professional inspections can also help prevent blockages from forming.
