In this guide, we’ll walk you through the common causes of toilet blockages, the best DIY methods to unclog a toilet, and when it’s time to call a plumber. Plus, we’ll share tips to prevent future blockages and answer some frequently asked questions. Let’s get your toilet flowing smoothly again!
What Causes a Toilet to Get Blocked?
Before fixing the problem, it helps to know what’s causing it. Here are the most common culprits:
Too much toilet paper – Even flushable paper can build up. Flushing non-flushable items – Wet wipes, sanitary products, cotton balls, and even small toys can cause major clogs.
Limescale & mineral buildup – Hard water can leave deposits that narrow pipes over time.
Foreign objects – Kids (or pets!) sometimes drop things in the bowl.
Tree roots or sewer line issues – If multiple drains are slow, the main sewer line might be blocked (this needs a pro).
If your toilet is slow-draining, overflowing, or making gurgling sounds, it’s time to take action.
Tools & Items You’ll Need
Most blockages can be cleared with basic household items:
Plunger (the best tool for most clogs)
Rubber gloves (for hygiene)
Hot water (not boiling—it can crack porcelain)
Dish soap (helps break down grease and waste)
Baking soda & vinegar (a natural unclogging combo)
Wire coat hanger (for stubborn blockages)
Toilet-safe drain cleaner (for tougher clogs)
If these don’t work, you might need a plumber’s snake (auger) or professional help.
DIY Methods to Unblock a Toilet
Method 1 – Hot Water & Dish Soap
Best for: Mild clogs caused by toilet paper or organic waste.
Remove excess water (if the bowl is full).
Squirt ½ cup of dish soap into the bowl.
Pour hot (not boiling) water from waist height to create pressure.
Wait 15–30 minutes, then flush.
The soap helps break down the clog, while the hot water pushes it through.
Method 2 – Use a Plunger
Best for: Most toilet blockages.
Seal the plunger over the drain hole (ensure a tight fit).
Push down firmly, then pull up sharply 10–15 times.
Flush to check if the water drains normally.
Pro Tip: Use a flange plunger (designed for toilets) for better suction.
Method 3 – Homemade Baking Soda Solution
Best for: Stubborn, smelly clogs.
Pour 1 cup of baking soda into the bowl.
Add 2 cups of vinegar (it will fizz—that’s normal!).
Wait 30 minutes, then pour in hot water.
Flush to see if it’s clear.
This combo dissolves organic waste and deodorizes the bowl.
Method 4 – Use a Wire Hanger
Best for: Objects stuck near the drain.
Straighten a wire hanger and cover the end with a cloth (to avoid scratches).
Gently push and twist to dislodge the clog.
Flush to test.
Method 5 – Toilet-Safe Drain Cleaners
Best for: Tough clogs (when natural methods fail).
Use an enzyme-based cleaner (safer for pipes than harsh chemicals).
Follow the product instructions carefully.
Avoid repeated use—chemicals can damage pipes over time.
When to Call a Professional Plumber
If you’ve tried all the DIY methods and your toilet is still blocked, it’s time to call a plumber. You may need professional help if:
Water backs up into other drains (main sewer line issue).
The clog keeps returning (possible pipe damage).
You suspect tree roots or a broken pipe.
Foreign objects (like toys or jewelry) are stuck deep in the pipes.

How to Prevent Future Blockages
Only flush toilet paper (no wipes, even “flushable” ones).
Use less toilet paper per flush.
Regularly clean drains with hot water + baking soda.
Install a drain screen to catch hair and debris.
Check for slow drainage early before it becomes a full clog.
