How to Fix a Blocked Toilet: Step-by-Step Guide for Quick Results

A blocked toilet is one of the most inconvenient plumbing problems you can face at home. Luckily, with the right approach, you can often fix it yourself without needing to call a plumber straight away. In this step-by-step guide, we’ll show you exactly how to fix a blocked toilet quickly and safely, including DIY methods you can try with or without a plunger.

Common Causes of a Blocked Toilet

Understanding why your toilet is blocked can help prevent it from happening again. Some of the most common causes include:

• Excess toilet paper – one of the leading culprits behind a clogged toilet.
• Non-flushable items – wipes, sanitary products, nappies, and cotton buds should never be flushed.
• Pipe build-up – in older homes, scale or tree roots can restrict water flow.

Whether you call it a stopped up toilet or a blocked loo, the causes are usually the same , too much waste or something that shouldn’t have been flushed.

Preparation Before You Begin

Before you start trying to remove a blockage, get prepared:

• Put on rubber gloves.
• Place old towels or rags around the base of the toilet.
• Keep a bucket nearby in case you need to scoop excess water.
• Turn off the cistern tap (usually located near the toilet base) to prevent overflow.

Step-by-Step Guide: How to Fix a Blocked Toilet

Step 1: Stop the water from rising

If the bowl looks like it might overflow, immediately turn off the water supply at the cistern tap.

Step 2: Try the hot water method

Boil the kettle, then let the water sit for a few minutes so it’s hot but not boiling (boiling water can crack porcelain). Pour the hot water slowly into the bowl to help loosen the blockage.

Step 3: Add dish soap

Squeeze in a generous amount of dish soap. This helps to lubricate the pipe and break down greasy build-up.

Step 4: Use a plunger

A plunger is one of the most effective tools for toilet blockages. Ensure the rubber end is fully submerged in water, then plunge firmly up and down for 15–20 seconds.

Step 5: Try a wire coat hanger or drain snake

If the blockage is still there, carefully use a drain snake or an untwisted coat hanger to break it up. Be gentle to avoid scratching the porcelain.

This is the tried-and-true process for how to fix a stopped up toilet in most Australian households.

How to Fix a Clogged Toilet Without a Plunger

If you don’t have a plunger on hand, don’t worry. There are a few simple alternatives you can try:

• Hot water and dish soap method – as described above.
• Baking soda and vinegar for a clogged toilet – pour one cup of baking soda followed by two cups of vinegar into the bowl. Let it fizz for 15–30 minutes before flushing with hot water.

When to Call a Plumber

Sometimes a toilet blockage is a symptom of a bigger issue, such as a blocked sewer line or tree roots in the pipes. Call a plumber if:

• Multiple toilets or drains in your home are blocked at the same time.
• DIY methods haven’t worked after several attempts.
• You experience frequent or recurring blockages.
