A clogged toilet is one of those household problems that always seems to happen at the worst possible time. Whether it’s just before guests arrive, first thing in the morning, or late at night, a blocked toilet can quickly become stressful.
The good news is that not every clogged toilet needs emergency plumbing. In many cases, a simple blockage can be cleared with the right approach. However, some toilet blockages are signs of a bigger plumbing issue that should be checked by a licensed plumber.
At GF James Plumbing, we’ve helped homeowners and businesses deal with clogged toilets for years. In this guide, we’ll explain what causes a clogged toilet, what you can safely try yourself, when it’s time to call a professional, and how to help prevent future blockages.
What Causes a Clogged Toilet?
Most toilet blockages happen because something prevents waste and water from flowing freely through the drain.
Some of the most common causes include:
- Too much toilet paper
- Flushing wet wipes, even those labelled “flushable”
- Children’s toys or other foreign objects
- Sanitary products
- Paper towels or tissues
- Nappies
- Tree roots growing into underground pipes
- Damaged or collapsed sewer lines
Many people assume a toilet can handle anything that fits down the toilet bowl, but that’s simply not the case. Toilets are designed to flush human waste and toilet paper only.
Signs You Have a Clogged Toilet
Sometimes the blockage is obvious, but other times the warning signs appear gradually.
Common signs include:
- Water rising higher than normal after flushing
- The toilet draining very slowly
- Gurgling sounds from the toilet
- Bad smells coming from the bowl or toilet drain
- Water backing up into nearby drains
- The toilet overflowing
If you notice any of these signs, avoid flushing the toilet again until you’ve identified the problem. Repeated flushing can cause an overflow and water damage.
What To Do When Your Toilet Is Clogged
If your clogged toilet hasn’t overflowed, there are a few safe steps you can try.
Stop Flushing
It can be tempting to keep flushing in the hope the blockage clears itself.
Unfortunately, this usually makes things worse.
If the water level is already high, another flush could send dirty water over the toilet seat and onto your bathroom floor.
Use a Toilet Plunger
A quality toilet plunger is often the best first step.
Make sure you’re using a flange plunger designed for toilets rather than a standard sink plunger.
Place the plunger firmly over the drain opening and use steady, controlled pushes and pulls to create suction. After several attempts, test the toilet with one flush.
Wait for the Water Level to Drop
If the bowl is very full, wait until the water level falls before trying again.
Trying to plunge an overflowing toilet usually creates more mess than results.
Use Warm Water
Pouring a bucket of warm to hot water (not boiling) into the toilet can sometimes help soften paper blockages.
Avoid boiling water because it can damage the porcelain and create sudden temperature stress.
What You Should Never Flush
One of the easiest ways to avoid a clogged toilet is knowing what doesn’t belong in it. Here are some items that can cause a clogged drain –
Never flush:
- Wet wipes
- Baby wipes
- Cotton buds
- Cotton balls
- Paper towels
- Tissues
- Nappies
- Sanitary products
- Dental floss
- Cat litter
- Cooking grease
- Food scraps
Even products advertised as flushable often don’t break down quickly enough and can contribute to serious blockages.
When DIY Isn’t Enough
Sometimes a clogged toilet is only the symptom of a much larger plumbing problem.
You should contact a licensed plumber if:
- The toilet keeps blocking.
- You have more than one blocked toilet.
- Other drains are backing up.
- You hear gurgling from multiple fixtures.
- Water is overflowing.
- You suspect tree roots in the drain line.
- You think something solid has been flushed.
Professional plumbers have specialist equipment that can safely remove stubborn blockages without damaging your plumbing.
How Professional Plumbers Clear a Clogged Toilet
Depending on the cause of the blockage, a plumber may use different methods.
These can include:
Drain Cameras
A CCTV drain camera system allows plumbers to inspect inside your pipes without unnecessary digging.
This helps identify:
- Tree root intrusion
- Broken pipes
- Pipe misalignment
- Heavy blockages
- Foreign objects
Electric Drain Machines
For stubborn blockages, electric drain cleaning equipment can remove built-up debris and restore water flow.
High Pressure Water Jetting
High pressure water jetting is one of the most effective ways to clear blocked drains.
The powerful stream of water removes grease, sludge, tree roots and other debris while cleaning the inside of the pipe.
Can Tree Roots Cause a Clogged Toilet?
Yes.
Tree roots naturally seek moisture and can enter tiny cracks in underground sewer pipes.
Once inside, the roots continue growing until they restrict water supply or completely block wastewater flow.
Signs of tree root problems include:
- Frequent toilet blockages
- Slow drains throughout the house
- Gurgling pipes
- Sewage smells outside
- Overflowing inspection openings
If tree roots are the cause, professional equipment is needed to clear the blockage and assess whether pipe repairs are required.
How To Prevent a Clogged Toilet
Preventing a clogged toilet is much easier than dealing with one after it happens.
Here are a few simple habits that make a big difference.
Only Flush Toilet Paper
Toilets are designed for human waste and toilet paper.
Everything else should go in the bin.
Don’t Use Too Much Toilet Paper
Large amounts of toilet paper can create blockages, particularly in older plumbing systems.
If needed, flush twice rather than trying to send everything through in one flush.
Keep an Eye on Young Children
Children are naturally curious and sometimes flush toys, toothbrushes or other objects in the toilet bowl.
Keeping the toilet lid closed can help prevent accidents and blocked toilets.
Schedule Regular Drain Inspections
If your home has older plumbing or large trees nearby, regular drain inspections can identify problems before they become expensive repairs.
Is a Clogged Toilet an Emergency?
Sometimes it is.
You should contact an emergency plumber if:
- Sewage is overflowing into your home.
- Multiple drains are backing up.
- You only have one toilet and it’s unusable.
- Water is causing damage to your property.
- The blockage is affecting your business.
Fast action can minimise damage and restore your plumbing sooner.

Frequently Asked Questions
Can a clogged toilet fix itself?
Small paper blockages may soften over time, but most clogged toilets won’t clear without some form of action. If the blockage remains after waiting, it’s best to use a plunger or contact a plumber.
Is it safe to use chemical drain cleaners?
Chemical drain cleaners are generally not recommended for toilets. They may damage plumbing components, create hazardous fumes and often don’t remove the actual blockage.
Why does my toilet keep clogging?
A toilet that regularly blocks may have a partial obstruction, tree root intrusion, damaged sewer pipes or an issue with the toilet itself. A professional inspection can identify the underlying cause.
Can flushing wipes clog a toilet?
Yes. Even wipes marketed as flushable often don’t break down like toilet paper and are one of the leading causes of blocked toilets and sewer problems.
