Blocked drains can be a major inconvenience, leading to unpleasant odours, slow drainage, and even water backups. Understanding the causes of drain blockages can help you prevent them and address issues before they become severe. In this blog, we’ll explore common and less common causes of blocked drains, signs to look out for, and how to prevent future problems.
Common Causes of Blocked Drains
Grease and Fat Build-Up
One of the most frequent causes of blocked drains is the accumulation of grease and fat. When you pour grease or fat down the sink, it can cool and solidify, sticking to the inside of the pipes. Over time, this build-up can restrict water flow and eventually cause a blockage. To prevent this, avoid disposing of grease down the sink and instead, dispose of it in a separate container.
Hair and Soap Scum
Hair and soap scum are common culprits in bathroom sinks and showers. Hair can easily get trapped in the pipes, while soap scum combines with hair to form stubborn clogs. Regularly cleaning drain covers and using a hair catcher can help minimize these blockages.
Food Scraps
Food scraps, especially large or fibrous items, can cause blockages in kitchen sinks. Even if you have a garbage disposal, it’s important to avoid putting large pieces of food down the drain. Use strainers and dispose of food waste in the compost or rubbish bin.
Foreign Objects
Sometimes, foreign objects like toys, sanitary products, or even small items accidentally dropped down the drain can lead to blockages. These objects can get stuck in the pipes, blocking water flow and potentially causing damage to your plumbing system. Ensure that only appropriate materials are disposed of through your drains.
Tree Roots
Tree roots are a less common but serious cause of blocked drains. Roots can infiltrate pipes through small cracks or joints and create blockages as they grow. This can lead to significant damage to your plumbing system. If you suspect tree roots are a problem, it’s essential to have your pipes inspected and addressed by a professional.
Signs of a Blocked Drain
Recognising the signs of a blocked drain early can prevent more serious issues. Look out for:
- Slow Drainage: Water taking longer than usual to drain away.
- Gurgling Noises: Unusual sounds coming from your pipes.
- Unpleasant Odors: Foul smells emanating from the drains.
- Water Backups: Water rising in sinks or toilets.
Preventing Blocked Drains
Regular Maintenance
Regular drain cleaning and inspection can help keep your plumbing system in good shape. Consider scheduling professional maintenance to address any potential issues before they become severe.
Proper Disposal Practices
Avoid disposing of grease, large food scraps, and non-flushable items down the sink or toilet. Using strainers and disposing of waste properly can help prevent blockages.
Using Drain Covers
Drain covers are effective in catching hair and other debris before they enter the pipes. Regularly clean and maintain these covers to ensure they work effectively.
When to Call a Professional
If you’re dealing with persistent blockages or suspect more serious issues, it’s best to seek professional help. For effective solutions, consider reaching out to experienced blocked drain plumbers. They can use specialized tools to diagnose and resolve the problem efficiently.
Conclusion
Understanding what causes drains to become blocked can help you take preventive measures and address issues quickly. By keeping your drains clean and following best practices for waste disposal, you can minimize the risk of blockages and keep your plumbing system running smoothly.
