How to Unclog a Blocked Toilet Without a Plunger





Introduction: How to Unclog a Blocked Toilet Without a Plunger

What would you do if your toilet got clogged on a Saturday evening when the shops are closed and you are about to host a curry and beer party?

This instructable will show you a simple method for unclogging a toilet using hot water and shampoo. While there are other methods of clearing a toilet drain, this is a great option for unclogging a toilet because you don’t have to touch the water.

You will need:

  • 1 clogged toilet (works best when someone has been overzealous with the toilet paper)
  • A generous amount of surfactant (i.e., Dawn Dishwashing liquid, shampoo, liquid soap, or any other cleaner that gets sudsy)
  • Hot (but not boiling) water
  • A bucket or a basin to transport water to toilet

This will only work with a toilet that is not overflowing and has some room to hold extra water.

(For squeamish people: The picture of the blocked toilet was not created with actual bodily excretions.)

Step 1: Add Shampoo and Hot Water.

Get your bottle of shampoo/ soap and squirt a generous amount into the bowl.

Follow that with a bucket of very hot water from the hot tap (not boiling).
Fill the toilet full but not overflowing.

The reason you should not use boiling is because it has been said that boiling water can cause the toilet bowl to crack (I have not personally tested this assertion though as I do not have the money to buy a new toilet).
Then go have a cup of tea and let the blockage 'marinate'.

Step 2: Return and See Your Handy Work.

Hopefully after a few minutes the water level will have lowered. (Hot water helps break up toilet paper quicker and the soap lubricates the passage of solid material).
If nothing has happened wait 10 minutes more. If still nothing has happened you will probably need to use a different method (or bail some of the water out and add more hot water/ soap).

If the water level is lower than before add more soap and more hot water (hot water does not need to be as hot as the first time as this time there is less water in the toilet to heat up).
Again wait for water to drain (this should be quicker).

Repeat the process until water flows freely.

Step 3: Done

Remind your party goers to treat your toilet with respect and only put bodily excretions and small amounts of toilet paper in.

How much is a generous amount? How long should I let it marinate? Should I fill the toilet full even with the water level low?


It also works with powdered laundry detergent after you let it get full of suds under the bathtub faucet

its gotta feel good that almost 5 years after OP people are signing up for an account just to say thank! thanks! it worked instantly.. you have saved our marriage...this time. lol.

Holy cr@p Batman, put some cheap shampoo and hot water down and it worked, nearly called the homeserve people, would have cost me £50. Brilliant.

I tried it and it worked in minutes. I had a clogged toilet that I was trying to flush waiting for it to go down and the flushing with a bucket but it was not working. I saw your page, followed the instruction and unvelievably, in minutes I was clog free. Thank you, thank you, thank you!

WOW!!!!!! the bowl cleared almost immediately.thanks.

Thank you! This simple process really does work - unclogged my bathroom in less than 5 minutes.

thank you, it worked very well in the first instance. I used coles dis-washing liquid and boiling water. waited for 10 minutes it did not work so I left to shops for grocery shoping when I returned I had a clean toilet. Wow amazing:)

just signed up to say thank you and how much trouble it saved me!! I pulled 6 kettle of almost boiled water down and the whole process took around 20 mins , I was about to give up hope and go out and get a plunger also contemplating getting a plumber, then voila, it all worked!!!

using dishwashing liquid also cleaned out the toilet bowl

This really works! Slightly blocked loo for a few weeks just kept on filling up. It just glugged away on the first bucketful of hot water and quite a lot of washing up liquid! Amazing. If it's still good on Monday I'll be really impressed.
