Stop using the toilet immediately
Put on gloves
Check the water level in the bowl
If water is near the rim, place a bucket or towels around the base to prevent overflow
Try a plunger (use a flange plunger if available)
Ensure there is enough water in the bowl to cover the plunger cup
If there isn’t enough water, add warm water from a bucket until the plunger cup is covered
Plunge with firm, steady strokes for 15–30 seconds
Pause, then repeat if needed
If plunging doesn’t work, try a toilet auger (closet auger)
Insert the auger into the bowl and turn the handle clockwise to feed the cable
Keep feeding until you feel resistance break through or the clog clears
Retract the auger slowly
Flush cautiously with small amounts of water if possible
If you have access to a wet/dry shop vacuum, use it to remove water and debris
Use the vacuum only if it can handle liquid and solids
Seal the vacuum hose to the drain opening as best as possible
Turn on the vacuum and remove water, then clear remaining blockage
Consider a drain snake specifically for toilets if you don’t have a closet auger
Avoid chemical drain cleaners for toilets
If the toilet is overflowing, shut off the water supply at the shutoff valve behind the toilet
Remove excess water using a bucket or wet/dry vacuum
After clearing, turn the water back on slowly
Test by flushing once carefully
If it still won’t drain, stop and contact a licensed plumber
