Blocked drains are a common and frustrating problem for Canberra homeowners. Not only do they cause inconvenience, but they can also significantly damage your property if left untreated.
To effectively prevent and address this issue, it’s crucial to understand the main causes behind these blockages.
This article will explore the common causes of blocked drains in Canberra homes. By identifying the root of the problem, you can take proactive steps to protect your plumbing system and avoid costly repairs.
Household Waste
Fats, Oils, and Grease (FOG)
Fats, oils, and grease, commonly called FOG, are among the most common culprits behind blocked drains in Canberra homes.
While they might seem harmless when washed down the kitchen sink, these substances pose a significant threat to your plumbing system.
How FOG Accumulates in Pipes
When fats, oils, and grease are poured down the drain, they appear to dissolve in hot water. However, as the water cools, these substances solidify and begin to cling to the interior walls of your pipes.
Over time, this accumulation builds up, creating a sticky, greasy substance that traps other debris, such as food particles and hair. The result is a narrowing of the pipe and a reduced water flow, eventually leading to a complete blockage.
The Negative Impact of FOG on Drainage Systems
The consequences of FOG build-up extend beyond clogged drains. When pipes become severely blocked, wastewater can back up into your home, causing damage to floors, walls, and personal belongings.
Furthermore, FOG contributes to larger-scale issues within the city’s drainage infrastructure. When multiple homes experience FOG-related blockages, it can overload the entire system, leading to sewer overflows and contamination of local waterways.
Food Scraps
While many people are aware of the dangers of pouring fats, oils, and grease down the drain, the impact of food scraps is often underestimated. Proper food waste disposal is crucial in preventing blocked drains.
Importance of Proper Waste Disposal
Food particles, from tiny rice grains to larger pieces of vegetable matter, can easily find their way down the kitchen sink. While small amounts might pass through without issue, consistent disposal of food scraps can lead to significant blockages.
Over time, these particles accumulate, forming a solid mass that can obstruct the flow of water.
How Food Particles Contribute to Blockages
Food particles act as a breeding ground for bacteria, which can contribute to the decomposition process and accelerate the formation of blockages. Additionally, these particles can become entangled with hair, soap scum, and other debris, creating a sticky, stubborn clog.
To minimise the risk of blockages, it’s essential to dispose of rubbish wisely, avoid pouring large amounts of food down the drain, and opt for a drain catcher to trap food particles before they enter the pipes.
Hair and Other Personal Care Products
Hair, soap scum, and other personal care products are common culprits behind blocked bathroom drains. The accumulation of these substances can create a thick, gunk that restricts water flow.
Build-up in Bathroom Drains
Every time you shower or bathe, hair and other debris are washed down the drain. Over time, these materials collect and intertwine, forming a mat-like substance that traps soap scum, toothpaste, and other residues.
This build-up gradually reduces the drain’s capacity, leading to slow drainage and eventually a complete blockage.
Prevention Tips
To prevent hair-related blockages, install a drain cover or hair catcher in your shower or bathtub. These devices effectively trap hair before it enters the drain.
Regularly cleaning these covers will help maintain optimal drainage. Additionally, avoid flushing wet wipes, cotton pads, or other personal care products down the toilet, as these items can contribute to blockages.
Plumbing Issues
Detergent and Cleaning Product Buildup
While essential for maintaining hygiene, excessive use of detergents and cleaning products can contribute to blocked drains. Many of these products contain chemicals that can be harmful to your pipes.
How Excessive Chemicals Can Harm Pipes
Over time, the residue from detergents and cleaning products can accumulate on pipe walls, forming a sticky film. This build-up can trap hair, food particles, and other debris, leading to blockages.
Additionally, some chemicals can be corrosive to pipes, causing damage and weakening the overall plumbing system.
Choosing the Right Cleaning Products
To minimise the risk of damage to your pipes, it’s essential to choose cleaning products carefully. Opt for environmentally friendly and biodegradable options whenever possible.
When using harsh chemicals, follow the instructions carefully and ensure proper ventilation. Remember, less is often more. Using the recommended amount of product is usually sufficient to achieve the desired results without harming your plumbing system.
Pipe Deterioration
Over time, pipes can deteriorate due to various factors, including age, material, and exposure to harsh chemicals. When pipes begin to break down, they become more susceptible to blockages.
Signs of Pipe Damage
Recognising the signs of pipe damage is crucial for preventing major plumbing issues. Some common indicators of pipe deterioration include.
Leaking Pipes
Water dripping or seeping from pipes is a clear sign of damage.
Low water pressure
Reduced water flow can indicate a partial blockage or a narrowing of the pipes due to corrosion.
Discoloured water
Rusty or cloudy water may signify pipe corrosion.
Gurgling sounds
Unusual noises coming from drains suggest potential blockages or pipe issues.
Sewer odours
Foul smells emanating from drains or sinks indicate a problem with the plumbing system.
The Role of Age and Material in Blockages
The age and material of your pipes play a significant role in their susceptibility to blockages. Older pipes are more likely to deteriorate and develop cracks or holes, which can lead to blockages.
Additionally, the type of material used in the pipes can affect their lifespan and resistance to corrosion. Cast iron pipes, for example, are prone to rust and corrosion, while PVC pipes are generally more durable.
Understanding the age and material of your pipes can help you anticipate potential problems and take preventive measures.
Tree Roots
Tree roots are a formidable enemy of plumbing systems. With their relentless search for water and nutrients, they can infiltrate pipes, causing significant damage and blockages.
How Tree Roots Invade Pipes
Tree roots are attracted to the moisture and nutrients found in sewers and drainpipes. Tiny cracks or joints in the pipes provide entry points for these invasive roots.
Once inside, the roots can grow rapidly, forming a dense network that obstructs the flow of water.
As the roots continue to expand, they can exert immense pressure on the pipes, causing them to crack or break.
Prevention and Removal Methods
Preventing tree root intrusion involves a combination of proactive measures and professional intervention.
Plant trees at a safe distance
When planting new trees, ensure they are located far enough away from sewer and drain lines to minimise the risk of root infiltration.
Regular inspections
Conduct periodic inspections of your plumbing system to detect early signs of root intrusion.
Root-killing chemicals
While effective in killing existing roots, these chemicals should be used with caution as they can harm the environment. Professional application is recommended.
Professional root removal
If you suspect tree root problems, it’s essential to contact a qualified plumber. They have the tools and expertise to locate and remove the roots without damaging your pipes.
By taking preventive measures and addressing root issues promptly, you can protect your plumbing system and avoid costly repairs.
External Factors
Heavy Rainfall and Stormwater
Heavy rainfall can significantly impact your drainage system. Excessive stormwater can overwhelm the capacity of pipes and drains, leading to blockages and waterlogging.
Overloading the Drainage System
When intense rainfall occurs, the volume of water entering the drainage system can exceed its capacity. This surge of water can carry debris, such as leaves, twigs, and soil, into the pipes, causing blockages.
Additionally, the increased water pressure can dislodge existing blockages, exacerbating the problem.
Preventive Measures
While it’s impossible to control the weather, there are steps you can take to minimise the impact of heavy rainfall on your drainage system.
Clear gutters and downpipes
Regularly remove leaves, debris, and other obstructions from gutters and downpipes to ensure efficient water flow.
Install gutter guards
Gutter guards can help prevent leaves and other debris from entering your gutters.
Check drains for obstructions
Before a storm, inspect drains for any blockages and clear them if necessary.
Consider a water tank
Collecting rainwater in a water tank can reduce the load on your drainage system during heavy rainfall.
Landscaping
Proper landscaping can help direct rainwater away from your home and reduce the burden on your drainage system.
Construction and Development
Construction and development projects can have a significant impact on the local drainage infrastructure, increasing the risk of blocked drains for residents in the area.
Impact on the Local Drainage Infrastructure
New developments often involve digging and excavation, which can disrupt existing drainage systems. Construction activities can also generate large amounts of sediment and debris, which can find their way into drains and cause blockages. Additionally, increased impervious surfaces, such as concrete and asphalt, from new buildings and roads can reduce the amount of water that infiltrates the ground, putting additional pressure on the drainage system.
Potential for Blockages
The influx of sediment and debris from construction sites can clog drains, leading to reduced water flow and potential flooding.
Furthermore, the increased volume of stormwater runoff from new developments can overwhelm the existing drainage infrastructure, resulting in blockages and backups.
To mitigate these risks, developers and builders must adhere to strict regulations and implement effective erosion and sediment control measures.
Residents in areas undergoing development should be aware of the potential for drainage issues and take steps to protect their own properties, such as regular drain inspections and maintenance.
