How to unclog a toilet
To unclog a toilet, stop flushing, use a flange plunger (the one with a soft extra cup underneath), seat it fully over the hole so it seals under water, and push down gently first, then pull and push firmly a dozen times, keeping the seal. The water dropping with a gurgle means it is clear. Flush once to test. A toilet auger handles clogs a plunger cannot.
Why it matters: It is the panic fix, and it is fast once you know the plunger technique.
Steps
- Stop flushing; if the bowl is close to overflowing, lift the tank lid and push the flapper down, or turn the valve behind the toilet clockwise.
- Put on gloves and lay old towels around the base.
- Use a flange plunger, which has a soft extra cup that fits into the hole.
- Seat it fully over the hole with enough water to cover the cup; add water if needed.
- Push down gently first to push out air, then push and pull firmly about a dozen times without breaking the seal.
- When the water drains with a gurgle, flush once and watch.
- If it is still blocked after several tries, use a toilet auger, cranking gently through the bowl.
Common mistakes
- Flushing again and again, which overflows the bowl.
- Using a flat sink plunger, which cannot seal in a toilet.
- Flushing wipes, even ones labeled flushable.
