Unblock a toilet Australia


There are few things more panic-inducing for a homeowner than flushing the toilet and watching the water level rise dangerously close to the brim. A blocked toilet is a common issue in Australian homes, but the good news is that you can usually fix it yourself without spending a fortune on an emergency plumbing call-out.

At AussieHomeFix, we have put together this quick, no-nonsense DIY guide to help you unblock your toilet fast and get your bathroom back to normal.

Essential Tools You Will Need

Before you start, grab the following items. You probably already have most of them lying around the house:

  • A good quality plunger (A flange plunger with a rubber flap at the bottom works best for toilets)
  • Heavy-duty rubber gloves
  • Old towels or newspapers (to protect the floor)
  • A bucket
  • Dishwashing liquid and hot water (for stubborn blockages)

Method 1: The Classic Plunger Technique

This is your first line of defense and works for 90% of toilet blockages.

Step 1: Prep the Area

Lay down your old towels or newspaper around the base of the toilet. Put on your rubber gloves. If the bowl is full to the brim, use a bucket to bail out some water so it doesn't overflow when you plunge.

Step 2: Position the Plunger

Place the plunger directly over the toilet drain hole. Ensure the rubber flange is completely covering the hole to create a tight vacuum seal. The plunger head needs to be submerged in water for this to work.

Step 3: Plunge Vigorously

Push down gently at first to let the air out, then pull up and push down vigorously without breaking the seal. Do this 10 to 15 times. The push-and-pull creates suction that shifts the blockage.

Step 4: Test the Flush

Remove the plunger. If the water drains rapidly, you've succeeded! Give it a test flush. If not, repeat the plunging process.

Method 2: The Hot Water and Dish Soap Trick

If you don't have a plunger, or if the plunging didn't quite work, try this plumbing hack.

Squirt a generous amount (about half a cup) of dishwashing liquid directly into the toilet bowl. Let it sit for 10-15 minutes. The soap acts as a lubricant for the blocked debris.

Next, pour a bucket of hot (not boiling) water into the bowl from about waist height. The force of the water combined with the slippery soap is often enough to push the blockage right through. Warning: Never use boiling water as it can crack the porcelain!

What NOT to Do

Avoid using harsh chemical drain cleaners. Not only are they bad for the Australian environment and waterways, but they can also damage older PVC pipes and generate dangerous fumes.

When to Call a Licensed Aussie Plumber

If you have tried both methods and the water still won't drain, or if water starts backing up into your shower or floor waste, stop immediately. This indicates a deeper blockage in your main sewer line, possibly caused by tree roots. Under Australian regulations, you will need to call a local licensed plumber with a drain camera and an eel or jetter to clear it safely.
