Blocked drains are one of the most frustrating and inconvenient plumbing issues that homeowners can face. When left untreated, they can lead to unpleasant odours, slow drainage, and even flooding. Fortunately, many of the causes of blocked drains are preventable with the right knowledge and care. In this blog post, we will explore the most common causes of blocked drains and provide helpful tips on how to avoid them.
1. Hair Buildup in Bathroom Drains
One of the most common causes of blocked drains in the bathroom is hair buildup. Whether it's from showering or brushing your hair, strands of hair can easily clog up your drain over time. This is particularly common in showers, bathtubs, and sink drains.
How to Avoid It: To prevent hair from clogging your drains, invest in a hair catcher or drain guard. Regularly cleaning these guards can help avoid any buildup. Additionally, try to dispose of any loose hair in the bin, rather than washing it down the drain.
2. Grease and Fat in Kitchen Drains
Pouring grease and fat down the kitchen sink is a major cause of blocked drains. Grease from cooking can solidify in the pipes, causing a blockage that can be difficult to remove. Over time, this solidified grease can also attract other debris, worsening the problem.
How to Avoid It: Always dispose of grease and cooking oils in a container and throw it in the bin. Avoid washing dishes with excess grease down the drain. Instead, use paper towels to wipe off oily residue before washing.
3. Food Waste in Kitchen Sinks
Leftover food and small particles that are washed down the kitchen sink can cause blockages, particularly if a waste disposal unit isn’t used. Over time, these particles accumulate and create a clog in the pipes.
How to Avoid It: Never pour food waste down the drain. Instead, use a food waste bin or composting system. For those with waste disposal units, make sure to run plenty of water while operating it to ensure that food particles are thoroughly washed away.
4. Foreign Objects in Toilets and Drains
One of the most common causes of blocked drains is the flushing of foreign objects, particularly in toilets. Items such as wet wipes, sanitary products, and cotton buds do not break down like toilet paper and can create a blockage that disrupts the drainage system.
How to Avoid It: Always dispose of non-flushable items in the bin. Never flush anything other than toilet paper down the toilet. This will help protect your drainage system and avoid costly repairs.
5. Tree Roots Invading Drain Pipes
Tree roots can sometimes invade your drainage system, particularly if there are cracks or loose fittings in the pipes. As the roots grow, they seek out water sources, and if they find their way into your pipes, they can cause significant blockages.
How to Avoid It: Regular inspections of your plumbing system, especially after heavy rain or storms, can help identify any issues early. If you have trees near your property, consider hiring a professional to check for root intrusion and take preventative measures.
6. Soap Scum Buildup in Bathroom Drains
Soap scum can build up in bathroom drains, particularly in areas with hard water. Over time, this soap residue can combine with other debris like hair and cause blockages.
How to Avoid It: Regularly clean your bathroom drains with a mild detergent or natural cleaning solution. Using a drain cover can also prevent hair and soap scum from accumulating in the pipes.
7. Bad Pipe Installation or Ageing Pipes
In some cases, blocked drains can occur due to poor pipe installation or ageing pipes. Over time, pipes can corrode, crack, or become misaligned, which can cause blockages.
How to Avoid It: Ensure that your plumbing is properly installed by a professional and have regular checks to detect any early signs of wear and tear. If you live in an older property, consider having your pipes inspected and replaced if necessary.
8. Chemical Drain Cleaners
While chemical drain cleaners are commonly used to clear minor blockages, they can sometimes worsen the situation. Overuse of chemical cleaners can cause damage to pipes, leading to leaks or more severe blockages.
How to Avoid It: Opt for natural methods to clear minor blockages, such as using a plunger or baking soda and vinegar. If you are unsure, it’s best to call a professional drainage service.
Conclusion
Blocked drains are a common issue, but with proper maintenance and care, many blockages can be avoided. By taking simple precautions, such as not flushing inappropriate items, disposing of grease properly, and maintaining your drains, you can save yourself from the hassle and expense of dealing with clogs. However, if you experience frequent drain blockages or suspect a more serious issue, it’s essential to consult with a professional.
