To unclog a toilet, you can try the following methods:
1. Plunger: Use a plunger to create suction and dislodge the blockage.
2. Hot water and dish soap: Pour hot water mixed with dish soap into the toilet bowl and let it sit for a while before flushing.
3. Toilet auger: Use a toilet auger to break up and remove the blockage.
4. Baking soda and vinegar: Mix baking soda and vinegar in the toilet bowl to create a fizzy reaction that may help break up the clog.
5. Chemical drain cleaner: Use a chemical drain cleaner specifically designed for toilets, following the instructions carefully.
If these methods do not work, it may be best to contact a professional plumber for assistance.
