Clogged Toilet, Bowl Overflows
The bowl or drain is clogged
First, prepare the floor around the clogged toilet should water overflow or splash out. If the bowl is overflowing or filled to the rim you will need to bail it out. Use rubber gloves, a bucket and a small container to empty about half of the water from the bowl.
If the bowl is empty fill it to half full with water.
Place a plunger flush over the drain opening in the bottom of the toilet. Quickly pump the plunger about a dozen times, then remove it with a quick motion. If the blockage is dislodged the water should rush away. If not, repeat the process as necessary.
If a plunger does not clear the clog an auger will likely do the trick. Be careful not to scratch the porcelain in the bowl when inserting the coil into the drain. Once the auger is fed into the drain turn it clockwise until you feel resistance. Then turn it counterclockwise. Repeat this process to clear the clog, then remove the auger from the drain. If the drain is not fully cleared try using the plunger again and then repeat with the auger if necessary.
Remove the toilet
If you are still not able to clear the clogged toilet you may need to remove the toilet to remove the blockage from below.
