Blocked Drains: Causes, Solutions, and When to Call a Professional

Category: Business | Author: distinctplumbing | Published: October 1, 2025

Blocked drains are a common problem that can quickly turn from a minor inconvenience into a major headache. Whether it\'s a slow-draining sink or a completely blocked pipe, a drain issue can disrupt daily life. In this article, we\'ll explore the causes of blocked drains, how to fix them, and when it\'s time to call a professional plumber.

What Causes Blocked Drains?

Blocked drains can happen in any part of your home\'s plumbing system. The most common causes of blockages include:

  • Grease and Fat Build-Up: One of the most frequent culprits behind blocked drains is the build-up of grease and fats. Over time, cooking oils, fats, and grease solidify when they cool down, creating a sticky layer inside the pipes. These substances catch food particles and other debris, causing a blockage.
  • Hair and Soap Residue: In bathrooms, hair is a big issue. When you wash your hair, bits of it can collect in the drain. Combined with soap residue, hair forms clumps that can block the flow of water, particularly in shower or bathtub drains.
  • Food Waste: In kitchens, food scraps are a major contributor to blockages. Even though garbage disposals may help, they\'re not foolproof. If you\'re washing large amounts of food waste down the drain, it can easily cause clogs in the pipes.
  • Tree Roots: Outside your home, tree roots can invade the plumbing system. Over time, roots can grow into pipes, especially if they\'re old or damaged. Once inside, roots can block water flow or even crack pipes.
  • Foreign Objects: Sometimes, the cause of the blockage is something unexpected, like a child\'s toy, jewellery, or even a piece of clothing. These items can find their way into drains and cause serious clogs.
  • Aging Pipes: Older pipes can develop cracks, which can lead to blockages. These cracks can also cause leaks, leading to more significant problems in your plumbing system.

How Can You Prevent Blocked Drains?

Preventing blocked drains is all about regular maintenance and being mindful of what goes down your pipes. Here are a few tips to keep your drains clear:

  • Avoid Pouring Grease Down the Drain: When cooking, pour used cooking oils or fats into a container, not the sink. This will help prevent a build-up in your pipes.
  • Use Drain Strainers: Install strainers in your kitchen and bathroom sinks. These can catch food particles, hair, and other debris before they go down the drain.
  • Regularly Clean Drains: Once a month, flush your drains with boiling water or a mixture of baking soda and vinegar. This can help prevent a build-up of grease, soap, and other materials.
  • Proper Disposal of Food Scraps: Instead of washing food scraps down the drain, put them in the bin. Use a compost bin if you prefer an environmentally friendly disposal method
  • Don\'t Flush Non-Flushable Items: Only flush toilet paper down the toilet. Items like baby wipes, cotton balls, and sanitary products can cause major blockages in your pipes.

When Should You Call a Blocked Drain Plumber in Adelaide?

While DIY methods can work in some cases, there are situations when you should call a professional blocked drain plumber in Adelaide. Here are some signs that you need expert help:

Persistent or Frequent Clogs

If you find that your drains are frequently becoming blocked, it could be a sign of a bigger problem, like tree roots invading your pipes or pipe corrosion. A plumber can diagnose the underlying issue and offer a long-term solution.

Slow Drains or Foul Smells

If water is draining slowly, or you notice foul smells coming from your drains, it\'s time to call a plumber. These are usually signs that something is caught deep in the plumbing system or that there is a build-up of waste material in your pipes.

Multiple Drains Are Blocked

If more than one drain is clogged at the same time, there\'s likely a blockage in the main sewer line. This can lead to serious damage if not fixed, so it\'s essential to get professional help as soon as possible.

You\'ve Tried DIY and It Didn\'t Work

If you\'ve tried the DIY methods mentioned earlier, but the clog still hasn\'t cleared, it\'s best to contact a professional. A plumber will have the right tools and expertise to deal with more complex blockages.

Leaking or Burst Pipes

If a blocked drain has caused pipes to leak or burst, immediate attention from a professional plumber is necessary to avoid water damage.
