Dealing with Blocked Drains: Causes, Consequences and Solutions
Posted on: 10 February 2025
Blocked drains are a common household problem that often strikes at the most inconvenient times. Whether it’s an overflowing sink or a sluggish shower drain, the underlying issue can quickly turn into a bigger and costlier problem if left unaddressed. Understanding the common causes, potential consequences and benefits of professional assistance is key to managing and preventing blocked drains.
Common Causes of Blocked Drains
Built-up Grease and Food Waste
Kitchen sinks are particularly prone to blockages due to grease, fat and food scraps being washed down the drain. Over time, these substances solidify and restrict water flow, leading to persistent and stubborn blockages.
Hair and Soap Scum
Bathroom drains, especially in showers or baths, often accumulate hair and soap residue. When these combine, they form clumps that stick to the pipe walls, reducing water drainage.
Foreign Objects
Items like sanitary products, wet wipes or even children’s toys can inadvertently end up in drains, particularly in toilets. These objects don’t break down easily and can lead to major obstructions.
Tree Roots and Outdoor Blockages
Outside drains aren’t immune. Tree roots can invade underground pipes in search of water, disrupting the flow of wastewater. Similarly, garden debris such as leaves and mud can clog outdoor drains if not properly cleared.
The Consequences of Ignoring a Blocked Drain
Property Damage
Water backups from blocked drains can cause flooding, leading to damage to floors, walls, carpets and furniture. This is particularly concerning when wastewater is involved, as it can also bring hygiene risks.
Bad Odours
Decomposing waste and stagnant water often produce unpleasant smells. Over time, these odours can spread through your home and become difficult to eliminate.
Health Risks
A blocked drain can create an environment for bacteria and mould to thrive. This poses health risks, particularly for those with allergies, asthma or weakened immune systems.
Higher Repair Costs
The longer a blockage is left untreated, the greater the potential for damage to your drainage system. Significant repairs can be far more expensive than addressing the issue early on.
Why Professional Help Is the Best Option
While DIY solutions might be tempting to save time and money, professional assistance is usually the most effective and reliable way to deal with blocked drains. Professionals not only have specialised tools, such as high-pressure jetting systems and drain cameras, but they also possess the expertise to identify and resolve underlying issues. For example, what seems like a minor grease clog could actually be a larger structural problem in your pipework. Additionally, attempting to clear a blockage yourself can sometimes damage pipes, especially with the misuse of chemical drain cleaners. Professional plumbers know how to safely address the issue without causing further harm, ensuring your drainage system is fully functional and problem-free.
