Why Do Drains Get Blocked and How Can You Clear Them?
Drain blocking problems are common in both homes and commercial properties. From slow drainage to complete blockages, these issues can disrupt daily routines and even cause long term damage if ignored. Understanding why drains get blocked and knowing how to clear them is essential for preventing costly repairs. With the right knowledge and support, you can keep your drainage system running smoothly and avoid unnecessary stress.
Common Reasons Why Drains Get Blocked
Drains can become blocked due to everyday habits, natural buildups, or underground pipe issues. Here are the most frequent causes:
Grease, Fat, and Oil Buildup
Kitchen drains often clog because oil and grease cool down and harden inside the pipes. Once this happens, they create a sticky layer that traps food scraps which eventually leads to a blockage.
Hair and Soap Scum
Bathroom drains regularly get blocked because hair easily collects in plugholes. When mixed with soap residue, it forms clumps that restrict water flow and cause slow drainage or complete blockages.
Wet Wipes and Hygiene Products
Wet wipes, nappies, cotton pads, and sanitary products are major causes of toilet blockages. Even wipes labelled as flushable do not break down properly and can quickly clog drainage pipes.
Tree Root Intrusion
Tree roots naturally grow toward moisture. If they find small cracks in underground pipes, they can force their way in. This causes blockages, leaks, and sometimes severe pipe damage.
Foreign Objects
Small objects, children’s toys, food waste, and excess toilet paper can accidentally get washed into drains and cause an obstruction. These often need professional tools to remove.
Collapsed or Damaged Pipes
If a pipe collapses, cracks, or becomes misaligned, water cannot flow efficiently. Waste collects in the damaged section which leads to frequent blockages. This often requires a more advanced solution.
How to Clear a Blocked Drain
There are several ways to clear a blocked drain depending on the severity of the problem. Some methods work for minor issues while others require professional expertise and equipment.
Hot Water and Simple DIY Solutions
Hot water can help melt grease and soften soap buildup inside your drains. A mixture of baking soda and vinegar can also help with mild clogs by creating a gentle reaction that breaks down debris.
Using a Plunger
A plunger can be effective for simple blockages in sinks or toilets. It works by creating pressure that pushes the clog through the pipe. This technique works best for shallow or soft blockages.
Drain Snakes and Basic Tools
A drain snake is a flexible tool that can reach deeper into the pipe. It breaks apart blockages and clears the path for water. While useful, it must be used carefully to avoid damaging the pipe walls.
Professional Drain Clearance Services
If DIY methods do not work, professional drain clearance is the safest and most reliable option. Experts use advanced equipment such as high pressure water jetting, CCTV drain inspections, and mechanical cutting tools to locate and remove stubborn blockages. Coastal Drains provides fast and efficient drain clearance services for both residential and commercial properties. High pressure jetting is particularly effective because it removes grease, roots, and other debris without damaging the pipes. If blockages keep returning, a CCTV survey can identify the underlying issue.
When Drain Lining Is the Best Solution
If your pipes are old, cracked, or repeatedly getting blocked, drain lining may be the best long term solution. Drain lining involves inserting a resin soaked liner inside the pipe. Once the liner hardens, it forms a new pipe within the existing one. This eliminates the need for excavation and restores the pipe to near new condition.
Benefits of Drain Lining
- Extends the lifespan of your pipes
- Reduces the risk of future blockages
- Provides a cost effective alternative to pipe replacement
- Minimises disruption to your property
- Prevents tree roots from entering pipes again
Drain lining is ideal for homes with aging pipe systems or properties experiencing recurring blockages caused by structural damage.
How to Prevent Blocked Drains in the Future
You can prevent most blockages by adopting simple habits and scheduling regular maintenance.
Avoid Pouring Grease Down the Sink
Instead of pouring grease away, collect it in a container and throw it in the bin.
Use Drain Guards
Drain guards help catch hair, food particles, and other debris before they enter the drainage system.
Dispose of Wet Wipes Properly
Even wipes labelled flushable should be placed in the bin to avoid long term drainage issues.
Schedule Routine Drain Clearance
Regular drain clearance keeps your drainage system free from buildup. Coastal Drains offers maintenance services to ensure your drains remain clear and efficient.
Consider Drain Lining for Older Pipes
If your drainage system is prone to recurring issues, drain lining can provide long lasting protection and minimise future repairs.
