How to Unblock a Toilet

Need to know how to unblock a toilet? Have a broken toilet? Don’t panic. We know it can be a stressful disruption to your everyday life. We all take operational toilets for granted. Depending on the severity of it though, it may be savable with your tools at home. Read on to find out what you can do to unclog a toilet and have it flushing freely again. Make sure you’ve got some rubber gloves ready just in case!

Methods of Unblocking A Toilet

There are actually several ways you can unblock a toilet and it’s not all about plungers. Although they are a reliable and easy way to do it, sometimes it may require a little extra help. You can use store-bought drain cleaners, homemade drain cleaners, augers or plumbing snakes, DIY plumbing snakes or even a vacuum.

If you are going to do a DIY job, it’s important to first be aware of what you are doing and do your research accordingly. Most of the methods mentioned above come with their own risks attached. Some may damage your pipes and drains, or potentially only make the situation worse by pushing the blockage further down the pipes.

If at any stage you are unsure of your ability to clear the blockage, you think you are only making it worse, or if the symptoms persist, call Metropolitan Plumbing for prompt blocked drains plumbers in your area.

What Is Blocking My Toilet?

Before you start wondering how to unblock a toilet, it’s also a good idea to first be aware of what exactly is blocking your toilet. The most common culprits are things like overuse of toilet paper, wet wipes, tissues and basically any other foreign object that is not meant to go in your toilet bowl and down the drain. For a better understanding, you can read more about what should never go down a drain on our blog.


Preparation is key, so make sure you have all the right equipment and set up before attempting to unblock a toilet. If you’ve flushed once and it is clearly blocked and not draining properly, DO NOT try to flush the toilet again hoping it will unblock. This will only cause the toilet bowl to overflow and create an awful mess. To minimise the clean up, lay down some newspaper sheets or some old towels to soak up any splash or overflow. Prepare yourself by putting on some rubber gloves to protect your hands from the unsanitary toilet water.

How To Unblock A Toilet With A Plunger

Plungers work best to unclog a toilet blocked by a buildup of toilet paper. Ball-headed plungers and flange-headed plungers work best, not the cheap suction cup style that is often portrayed in cartoons and the like. Run the plunger under some hot water prior to beginning to soften the rubber, helping to create a seal with the toilet bowl. Insert the head entirely into the water and make sure it covers the entire hole. If you need to add water you can do so from the tap. You may now proceed to pump the plunger back and forth to dislodge the blockage. It may not work immediately, but you’ll know it when it happens. Once you think you’ve unclogged the toilet, flush the toilet to make sure it’s all draining properly.

How to Unblock A Toilet With Chemical Solutions

There are three kinds of chemical solutions you may use to unblock a clogged toilet.

  1. Enzyme products
  2. Home made drain baking soda and vinegar cleaner
  3. Drain cleaning chemicals

These have been listed in order of which you should attempt to use them. Enzyme products are by far the best way to clear a blockage. They contain a mixture of enzymes that break down and liquify solid waste and are often found in stores like Bunnings, in the plumbing supplies aisle. They are the far safer alternative to your usual drain cleaners that are full of harmful chemicals. Enzymes won’t harm your pipes and are much better for the environment. With these store-bought solutions, simply follow the instructions outlined on the packaging for the most effective results.

The other option you can use is a homemade baking soda and vinegar solution, if you don’t want any chemicals in your pipes at all. To make this you will need:

  • 2 litres hot water
  • 1 cup baking soda
  • 2 cups vinegar

For this homemade mixture, pour the hot water into the toilet bowl, followed by the vinegar and baking soda and leave overnight. The solution will fizz up a great deal, but should hopefully, safely clear the blockage by breaking it down. Note, this, and other chemical solutions, will only work for organic matter blockages. If you’ve successfully done these steps but still find the blockage persists, it means you may have a hard obstruction.

Plumbing Snake

A plumbing snake, also known as an auger, is a long flexible rod with a head attachment that can snake its way deep down into the toilet drains. These are best used when the blockage is far down the pipes and solid in nature. Chances are if the situation is bad enough to need a plumbing snake, you most likely need a plumber to help. However, if you’re determined to DIY it, keep on. It’s fairly self-explanatory – insert the rod into the drain until you feel the obstruction, then twist the auger to make the sharp head spin. This will break up the obstruction into smaller pieces, making it easier for it to flush away.

DIY Tools

You can also attempt to use a homemade type of auger by cutting a wire coat hanger and extending it out. Then wrap a rag or cloth around one end and insert it into the drain like you would a plumbing snake. Without the attachable sharp head, all you can do here is push to try and dislodge the obstruction. This is a risky one as you could potentially just move the blockage deeper into the drain without loosening it, so this is advised against.


The most far fetched solution to unblock your toilet is definitely a last resort. All the other steps involved pushing the blockage down the drain, this one involves bringing it back up. You can suck the blockage out with a vacuum. However, not just any household vacuum, you will need a wet/dry vac. If you’ve got your hands on one, first suck all the water out of the toilet bowl. Wrap a towel around the hose so that it forms a seal around the drain hole as you insert the hose a few inches in, then suck away. Be sure to have some rubber gloves for this job! There are no guarantees but it may suck out the clog. Once again, this is the last resort.
