2. Put the brush inside a plastic grocery bag and wrap the bag tightly around the brush head. Secure it by either tying the two ends together around the brush handle or with a rubber band.
3. Stick the brush into your blocked toilet and push it down the hole until it hits the bottom of the bowl (no need to shove it down the pipe, just in the toilet bowl itself).
4. Making sure the hole is mostly stuffed closed with the plastic bag, pump the toilet brush vigorously up and down a few times like you would if you were using a plunger. Within seconds, you should hear a quick sucking noise and the contents of your blocked toilet will be sucked down the pipe. And that’s it.
