Understanding Common Causes of Toilet Clogs
Before you dive into the process of how to unclog a toilet, it’s essential to understand the causes of a clogged toilet. Knowing what is likely to cause a blockage will help you address the issue more effectively and prevent it from happening again in the future.
- Excessive Toilet Paper: One of the most common causes of clogs is using too much toilet paper in a single flush. Toilets, especially older models, may not have enough flushing power to handle large amounts of paper at once.
- Non-Flushable Items: Many people mistakenly flush items that are not meant to be flushed. These can include things like wet wipes, sanitary products, cotton balls, and even paper towels. These items don’t dissolve easily and can quickly cause blockages.
- Low-Flow Toilets: Older toilets or low-flow toilets might struggle to push waste through the pipes with enough force, leading to frequent clogs. These toilets might also suffer from a poor design or an aging internal system.
- Foreign Objects: Children, in particular, are known for flushing small objects down the toilet, such as toys, which can create serious clogs. These items can block the toilet’s drain and make it difficult for water to flow.
- Aging Plumbing: Over time, pipes can accumulate mineral deposits, grease, and other debris, narrowing the passageways. This build-up can make clogs more frequent and harder to resolve.
How to Unclog a Toilet Using a Plunger

One of the most basic and effective tools for clearing a clog is a toilet plunger. If you’re wondering how to unclog a toilet, this is the first tool you should try. Here’s how to use it effectively:
- Choose the Right Plunger: Make sure you have a toilet plunger (also known as a flange plunger). This type of plunger has a rubber flange at the bottom that fits snugly into the toilet drain and creates a better seal than a standard sink plunger.
- Position the Plunger: Place the plunger into the toilet bowl, ensuring that the rubber flange is completely submerged in water. If the water level is low, add some more water to the bowl to ensure the plunger is submerged.
- Create a Seal: Push the plunger down gently to create a strong seal over the toilet drain. The plunger should form a tight fit to maximize pressure.
- Plunge Up and Down: Using firm, consistent pressure, push the plunger up and down in a rhythmic motion. Be careful not to pull it all the way out of the water, as you want to maintain suction. Continue this for about 15-20 seconds.
- Flush the Toilet: After several plunging attempts, flush the toilet. If the water drains normally, the clog has been cleared. If the water doesn’t go down, you may need to try other methods.
How to Use a Plumbing Snake (Auger) for Deeper Clogs
Sometimes, the plunger isn’t enough to break up stubborn clogs. In this case, a plumbing snake (also known as a toilet auger) can be your best bet. Here’s how you can use a plumbing snake to resolve your toilet clog:
- Insert the Auger: Begin by inserting the coiled end of the auger into the toilet bowl. Slowly feed the auger into the drain, turning the handle to push it further into the pipe.
- Break Up the Clog: As you feed the auger into the pipe, you will feel resistance when you encounter the clog. Keep turning the handle to either break up the blockage or grab onto the object causing the obstruction.
- Retrieve the Object: If the auger hooks onto the object causing the blockage, gently pull it out. If you’ve managed to break up the clog, continue feeding the auger through the pipe to clear the remaining debris.
- Remove the Auger and Flush: Once the clog has been cleared, carefully remove the auger from the toilet and test the flush. If the water drains freely, you’ve successfully solved the problem.
How to Unclog a Toilet with Dish Soap and Hot Water
If you’re not keen on using a plunger or auger, there’s a simple method involving dish soap and hot water that can help loosen a clog. Here’s how to use this method to solve your toilet problem:
- Add Dish Soap: Pour about a cup of dish soap into the toilet bowl. Let it sit for 10-15 minutes. The soap will help lubricate the pipes and make it easier for the clog to break up.
- Heat the Water: While you’re waiting, heat about a gallon of water on the stove. Be sure to use water that is hot but not boiling. Water that is too hot could crack the toilet bowl.
- Pour the Hot Water Into the Toilet: Slowly pour the hot water into the toilet from about waist height. The pressure combined with the soap will help break up the clog.
- Wait and Flush: Allow the mixture to sit for another 10-15 minutes before flushing the toilet. If the water drains properly, the clog has been cleared.
How to Unclog a Toilet with a Wet/Dry Vacuum
In some cases, a wet/dry vacuum can be helpful for sucking out the clog. This method is a bit more involved but can be effective if other methods have failed. Here’s how to use a vacuum:
- Set Up the Vacuum: Make sure you have a wet/dry vacuum that’s designed to handle liquids. Attach the appropriate nozzle to the vacuum and place it in the toilet bowl.
- Vacuum the Water and Clog: Turn on the vacuum and allow it to suck out the water and debris causing the clog. Be patient, as this process may take a little time.
- Test the Flush: Once the vacuum has removed the clog, test the flush to ensure that the toilet drains freely. If not, repeat the process or try other methods.
When to Call a Professional Plumber

If you’ve tried several methods and the toilet is still clogged, it may be time to call in a professional plumber. Here are some signs that you need expert help:
- Multiple Clogs: If your toilet repeatedly clogs, there may be an issue with your sewer line or plumbing system that requires professional attention.
- Sewage Backups: If other drains in your home are also slow or backing up, there may be a blockage in your main sewer line. A plumber can perform a more thorough inspection.
- Unusual Sounds or Odors: If you hear gurgling sounds or notice unpleasant odors from the toilet, it may be a sign of a deeper issue.
- No Improvement After DIY Methods: If the clog remains after trying plungers, augers, and other DIY methods, calling a plumber will help identify the cause of the problem and fix it quickly.
How to Prevent Future Clogs in Your Toilet
Now that you know how to unclog a toilet, it’s important to take steps to avoid clogs in the future. Here are some tips to help keep your toilet functioning properly:
- Use Toilet Paper Sparingly: Don’t flush excessive amounts of toilet paper at once. If you need more, flush between uses.
- Don’t Flush Non-Flushable Items: Avoid flushing wipes, cotton balls, paper towels, or other non-flushable materials. These items don’t break down easily and can cause blockages.
- Check for Foreign Objects: Be mindful of small objects that may accidentally fall into the toilet, especially if you have young children. These objects can easily create blockages.
- Perform Regular Maintenance: Clean your toilet regularly and perform basic plumbing maintenance to ensure everything is functioning properly. If you notice any issues, address them quickly before they escalate.
