Blocked drains are among the most frequent plumbing problems encountered by both households and businesses throughout Australia. At Pinnacle Plumbing, we’ve observed how even a small blockage can escalate rapidly when not addressed promptly. From sinks that drain slowly and toilets that gurgle to standing water around your premises, blocked drains can interfere with everyday activities and may lead to significant damage if ignored.
In this guide, we’ll walk you through the causes of blocked drains, how to unblock a badly blocked drain and the best solutions to keep your plumbing system running smoothly.
What Causes Blocked Drains?
Blocked drains don’t happen overnight. In most cases, they build up over time due to everyday usage.
Common causes include:
- Grease and food waste – Often poured down kitchen sinks, these substances harden and restrict water flow.
- Hair and soap residue – A major culprit in bathroom drains.
- Tree roots – Invasive roots can enter underground pipes and cause severe blockages.
- Foreign objects – Items like wipes, sanitary products and paper towels can clog pipes.
- Mineral build-up – Over time, minerals in water can accumulate and reduce pipe diameter.
Understanding the cause is the first step toward choosing the right solution.
Signs You Have a Blocked Drain
Blocked drains usually give warning signs before becoming severe. Keep an eye out for:
- Slow drainage in sinks, showers, or bathtubs
- Unpleasant odours coming from drains
- Gurgling sounds in pipes
- Water backing up or overflowing
- Toilets not flushing properly
If you notice any of these issues, it’s best to act early to prevent further damage.
How to Unblock a Badly Blocked Drain?
This is one of the most common questions we get at Pinnacle Plumbing. While minor clogs can sometimes be handled at home, badly blocked drains often require a more thorough approach.
Here are a few methods you can try:
1. Boiling Water
Pouring boiling water down the drain can help dissolve grease and soap build-up. This is a simple first step for mild blockages.
2. Plunger
A plunger creates pressure to dislodge the blockage. It’s particularly effective for sinks and toilets.
3. Baking Soda and Vinegar
This natural solution can help break down organic material. Pour baking soda followed by vinegar, let it sit and flush with hot water.
4. Drain Snake or Auger
A drain snake can physically remove debris stuck deeper in the pipe.
Important Note:
If these methods don’t work, the blockage may be deeper in your plumbing system. Forcing DIY solutions can sometimes make the problem worse.
What Is the Best Solution to Unclog Drains?
While DIY methods can help with minor issues, the most effective and long-term solution is professional drain cleaning.
At Pinnacle Plumbing, we use advanced tools and techniques to ensure your drains are cleared safely and completely.
Our professional solutions include:
✔ High-Pressure Water Jetting
This method uses powerful water jets to remove stubborn blockages, grease and debris from pipes without damaging them.

✔ Pipe Repairs and Replacement
In cases where pipes are damaged, we provide reliable repair or replacement solutions to restore proper flow.
Why You Should Avoid Chemical Drain Cleaners
Many store-bought drain cleaners promise quick results, but they often do more harm than good.
- They can damage your pipes over time
- They are harmful to the environment
- They may not fully remove the blockage
For a safe and effective solution, it’s always better to rely on professional services.
Preventing Blocked Drains
Preventing drain problems is more effective than dealing with them after they occur. Adopting a few straightforward habits can go a long way in avoiding clogs and expensive plumbing repairs. Never pour grease or oil down the sink, since they solidify over time and can obstruct water flow. Installing drain strainers is a simple but useful measure to trap hair and debris before they enter the pipes. Similarly, dispose of food scraps in the trash instead of washing them down the drain. In bathrooms, only flush toilet paper items such as wipes and sanitary products should never be flushed, as they frequently lead to blockages. Regular professional plumbing checkups also help maintain system performance. Following these practical steps can keep your drains functioning well and reduce the risk of major issues later on.
