Clogged Toilet

Quick answer: Don’t flush again if the bowl is near the rim (This Old House). Use a flange (toilet) plunger with a tight seal and a pulling stroke; if that fails, use a toilet / closet auger, never a regular drain snake, which can scratch the porcelain (This Old House). Recurring clogs, sewage in sinks or tubs, or a clog you can’t clear mean it’s time for a plumber.

- Stop flushing & stop the waterFREE · 1 min
If the bowl is already full, don’t flush: This Old House’s Richard Trethewey notes a full flush adds about two more gallons. If water keeps rising, turn the shutoff valve behind the toilet clockwise; if you can’t reach it fast enough, lift the float arm to cut off the water (Bob Vila). - Prep the areaFREE · 5 min
Put on rubber gloves, lay towels around the base, and bail excess water from an over-full bowl into a bucket (This Old House). - Plunge the right wayFREE if you own one · 5 min
Use a flange-style or beehive plunger made for toilets. Lower it in at an angle so the cup fills with water, seal it over the drain opening, then plunge for 20–30 seconds and test with a flush (This Old House). Trethewey recommends emphasizing the pull: the trapway narrows as it curves down, so pushing hard can pack the clog in tighter (This Old House). - Try hot water & dish soap (minor clogs)FREE · 30–60 min
For a minor clog, pour hot—not boiling—water with a few drops of dish soap into the bowl (This Old House). Bob Vila advises against caustic drain cleaners, which may damage toilets and pipes. - Use a toilet (closet) augerTOOL
Pull the handle back so the cable sits inside the curved, sleeved end, set it in the drain, then push down while cranking clockwise until you hit resistance. Pull back to hook the clog or work it forward and back to break it up, then remove the auger and test-flush with the tank lid off so you can stop an overflow (Bob Vila). A rental runs about $15 a day per Bob Vila. Turn the handle slowly to avoid damaging the porcelain (This Old House). - Call a plumberPRO
See below.
⚠ When to call a plumber: recurring clogs, severe backups, sewage coming up in sinks or tubs, or unusual sounds or odors from drains (This Old House); a clog you still can’t clear after persistent snaking, one beyond about 6 feet, or a toilet that needs to be removed (Bob Vila, quoting Kodi Wilson). Bob Vila’s expert also advises homeowners not to use a powered snake themselves. Renting? See what you can fix vs. call your landlord.
