Can a Clogged Toilet Cause a Pipe to Burst?

When you flush your toilet, the waste and water go down a pipe that leads to the city sewer system.

If something is blocking that pipe, the wastewater can back up into your home. This can cause a lot of damage, and it can also be dangerous.

In this blog post, we will discuss what can happen if your toilet is clogged, and we will also provide some tips on how to prevent this from happening.

Can Clogged Toilet Cause Pipe to Burst?

Yes, a clogged toilet can cause a pipe to burst. When the toilet is flushed, the water pressure can build up and cause the pipe to burst. This can lead to a lot of damage, and it can also be dangerous.

People often have a misconception that if the pipe is not freezing, it won’t burst. While it’s partially true that a burst without freezing the pipe is unlikely, it can happen.

Due to the building up of pressure inside the pipe, it can burst out and create a mess. And if that happens, it’s an expensive repair that can cost you a lot of money.

How to Prevent Clogged Toilet To Not Burst?

There are a few things you can do to prevent your toilet from becoming clogged and causing your pipe to burst:

  • Do not flush anything other than human waste and toilet paper down the toilet.
  • If you have a septic tank, have it pumped regularly.
  • Do not put cooking grease, coffee grounds, or eggshells down the drain.
  • Do not flush feminine hygiene products, diapers, or paper towels down the toilet.

If you follow these tips, you can help prevent your toilet from becoming clogged and causing your pipe to burst.

However, you may have an already clogged toilet. Well, in that case, use a plunger to try and unclog it.

If you can’t unclog it right away and plumbers aren’t available soon, you can do these things to avoid any damage to the toilet or plumbings-

Don’t Use the Toilet

If you can’t unclog the toilet, don’t use it. It may seem like common sense, but a lot of people make the mistake of using a clogged toilet, which can only make the problem worse.

Plus, you should take the plan realtor gave you when buying the house to see if there is any other toilet connected to that same pipe. If it is, avoid using that too.

Use Snake to Remove Clog or Release Pressure

If you’re feeling confident, you can try to remove the clog with a snake. This is a long, flexible tool that you insert into the toilet to push the clog through.

If the clog has multiple layers or it’s complicated, you may still use the snake to release pressure built up on one side of the pipe to avoid a pipe burst situation.

Ensure Warm Temperature in the Pipe

If you are in cold weather areas and you have a clogged pipe, you must ensure that the pipe isn’t freezing until professionals come and fix the issue.

Ensure optimal furnace performance so that the issue doesn’t become worse.

And note that, these are only temporary solutions until you can get professional help. Do not try any other methods as it may cause further damage that will end up costing you more money in repairs.


A clogged toilet can cause a pipe to burst, which can lead to a lot of damage.

It is important to take measures to prevent your toilet from becoming clogged, and you should also know what to do if your toilet does become clogged.
