How to clear a blocked toilet?(and Who to Call)

Blocked toilets are frustrating, inconvenient, and let’s be honest a bit gross. Whether it’s a one-off problem or a recurring plumbing issue, knowing how to unblock a blocked toilet, what causes the blockage, and when to call a professional can save you time, money, and stress.

This page will walk you through every aspect of blocked toilets using clear, easy-to-follow answers based on what people actually search for online.

What Causes a Blocked Toilet?

Understanding why your toilet keeps getting blocked is the first step in preventing future issues.

  • Flushing Non-Flushables Wet wipes, paper towels, feminine hygiene products, and even too much toilet paper can lead to clogs.

  • Toilet Paper Overuse Especially in older or low-flow toilets.

  • Foreign Objects Kids’ toys, air fresheners, or small toiletries.

  • Drainage System Issues Tree roots, poor pipe slope, or collapsed pipes.

  • Blocked Vent Pipes Can cause suction issues that lead to poor flushing.

How Do I Know If My Toilet Is Blocked?

Here are signs your toilet is blocked:

  • Water rising too high when flushed

  • Gurgling sounds in other drains

  • Water draining slowly or not at all

  • Unpleasant smells from the bowl

How to Clear a Blocked Toilet – DIY Methods

If the blockage isn’t severe, try these steps first:

1. Plunger Power

Use a flange plunger. Seal the drain and plunge gently at first, then with force.

2. Hot Water & Detergent

Pour a bucket of hot (not boiling) water with dish soap. Let it sit for 20–30 minutes.

3. Toilet Auger (Plumbing Snake)

Insert it into the bowl and rotate until the obstruction is cleared.

4. Enzyme Cleaners

Safe for pipes and septic systems. Breaks down organic waste over time.

Will a Blocked Toilet Clear Itself?

Sometimes… but usually not. If it’s a soft blockage (toilet paper), it might clear overnight. But if your toilet has been clogged for more than a few hours, don’t wait.

Call Plumbologist and we’ll handle it before it gets worse.

Can a Blocked Toilet Cause a Flood?

Yes. Water overflow from a blocked toilet can damage floors, walls, and ceilings below. Act fast especially if water levels are rising after every flush.

How do I clear a blocked toilet myself?

Start with a plunger (preferably a flange style) and create a tight seal around the drain. If that doesn’t work, try pouring hot (not boiling) water mixed with dishwashing liquid like Morning Fresh. For more stubborn clogs, a toilet auger or enzyme cleaner from Bunnings can help break it down safely.

Will a blocked toilet eventually clear itself?

In some cases, a soft blockage (like excess toilet paper) may break down over time. However, this isn’t guaranteed. If the water isn’t draining or starts rising, it's best to act quickly or call a licensed plumber before it turns into a bigger issue.

How do I know if my toilet is blocked or something else is wrong?

If your toilet is slow to flush, makes gurgling sounds, or water rises too high before draining or doesn’t drain at all it’s likely blocked. If other drains in the house (e.g., shower or sink) are affected too, the blockage could be further down the line.

Can a blocked toilet cause a flood?

Yes, it can. If a clog isn’t cleared quickly, every flush may cause water to overflow, leading to water damage in your bathroom and even to the rooms below in double-storey homes. If water starts backing up, call an Emergency Plumber immediately.

What’s the best product in Australia to unblock a toilet?

For DIY solutions, Nature Flush Enzyme Cleaner or EcoCare Activator are eco-friendly and effective. You can find them online or in plumbing stores. Avoid harsh chemical drain cleaners like Drano in toilets—they can damage porcelain and PVC pipes.
