One of the most common plumbing problems that homeowners deal with is blocked drains. They can be inconvenient and messy and even lead to various property damage if not addressed quickly. Wondering how to prevent clogged drains? In this blog, we’ll explore the most common causes of blocked drains and share simple drain clog prevention tips to help keep your plumbing flowing smoothly all year round.
Causes of Blocked Drain
So, what causes blocked drains? Let’s find out the reasons and how we can avoid them.
Grease and Fat Buildup
The disposal of various fats, oils, and grease (FOG) is one of the main causes of drain blockages in kitchen sinks. When hot, these substances flow easily down the drain. However, when they cool, they solidify and stick to the pipe walls, causing a persistent blockage over time.
Prevention Tips:
- Do not pour grease or oil down the sink. Instead, let it cool and dispose of it in the bin or a dedicated grease container.
- Use sink strainers to catch proper food particles and clean them regularly.
- Call a professional plumber for routine drain cleaning to remove existing buildup and keep pipes grease-free.
Hair Accumulation
Hair buildup is a common problem with bathroom drains, particularly in sinks and showers. Over time, hair combines with soap scum and other debris to form large blockages that restrict water flow.
Prevention Tips:
- Use hair catchers or drain guards in bathroom drains. Clean these guards weekly to prevent buildup.
- Brush your hair before showering to reduce shedding in the bathroom.
- Schedule periodic bathroom drain maintenance with professional plumbers to prevent stubborn blockages.
Tree Roots Infiltration
Tree roots are a hidden danger for underground drains. As they search for water sources, roots can infiltrate even the tiniest cracks in your pipes. Once inside, they expand and block water flow, sometimes even causing the pipe to collapse.
Prevention Tips:
- To prevent clogs, avoid planting trees and shrubs near your main sewer line.
- Schedule regular professional drain inspections, especially if your home is surrounded by large trees.
Toiletries and Non-Flushable Items
It’s a common misconception that things like paper towels, cotton buds, sanitary goods, and baby wipes can be flushed. However, these products do not break down like toilet paper and can quickly cause blocked toilets.
Prevention Tips:
- Only flush human waste and toilet paper.
- Place a bin in your bathroom for all other waste.
- Educate children and guests about what shouldn’t be flushed.
- Have blocked toilets professionally cleared to avoid sewer backups and hygiene issues.
Soap Scum and Residue
Traditional bar soaps include grease or fat, which can react with water’s minerals to create soap scum. This material accumulates along pipe walls over time and slows down drainage, particularly in bathroom sinks, bathtubs, and showers.
Prevention Tips:
- Switch to liquid soap or natural alternatives with fewer fats.
- Use vinegar and baking soda as a monthly natural cleaner.
- Have professionals hydrojet your pipes to remove hardened soap scum and restore flow.
Food Waste and Coffee Grounds
Even if you have a garbage disposal, large chunks of food, starchy leftovers like rice and pasta, and coffee grounds should never go down the drain. These materials expand with water and can block pipes quickly.
Prevention Tips:
- Scrape plates into the bin before rinsing.
- Use compost bins for coffee grounds and food scraps.
- Consider professional services to clear stubborn food blockages.
Foreign Objects
Children are inherently curious, and occasionally, their curiosity leads to toys or strange objects being pushed down the sink or flushed away. Even for adults, small objects like jewellery, bottle caps, or makeup wipes can slip and cause clogged drains.
Prevention Tips:
- Install drain covers in sinks and bathtubs.
- Keep small objects and children’s toys away from bathrooms.
- Monitor young children closely in bathrooms to avoid accidental flushing.
- Hire professionals to retrieve stuck objects with minimal pipe damage.
Poor Pipe Installation or Misaligned Pipes
In older homes or during DIY renovations, pipes can be improperly installed or misaligned. It is one of the most common causes of clogged drains. Over time, this leads to dips or cracks where waste accumulates, resulting in frequent clogs.
Prevention Tips:
- Have your plumbing inspected by licensed blocked drain plumbers like LCL Plumbing and Drainage.
- Ensure all installations and renovations comply with local plumbing codes.
- Consider professional pipe relining for older homes as a preventative upgrade.
Collapsed or Damaged Pipes
Pipes have a limited lifespan. They may fracture, collapse, or shift as a result of weather extremes, corrosion, wear and tear, and ground movement. These structural issues of broken pipes can either trap debris or stop the flow of water entirely.
Prevention Tips:
- Schedule CCTV drain inspections every few years.
- Watch for signs like frequent backups, foul odours, or slow drainage.
- Replace or reline old pipes by professionals before major failures occur.
Heavy Rain and Stormwater Overflow
During intense storms, external drains can become overwhelmed with leaves, mud, and debris. This causes water to back up into the home, especially in properties with poor drainage or blocked gutters.
Prevention Tips:
- Regularly clean your gutters and outdoor drains.
- Trim overhanging trees and bushes near your roof and pipes.
- Contact professionals to install proper stormwater drains or rainwater tanks.
When to Call a Professional
While DIY techniques like plungers or natural cleaners can frequently remove small clogs, recurrent or chronic blockages indicate more serious problems. If you’re dealing with slow drains, gurgling noises, water backups, or bad smells, it’s time to call in the professionals.
At LCL Plumbing and Drainage, we use advanced diagnostic tools like CCTV drain cameras and hydrojetting to pinpoint and eliminate the problem efficiently.
