Repair most toilet clogs using a plunger. If the plunger does not work, advance to a toilet auger. If other fixtures in the home are not draining, the problem is likely in the main drain line and may require the services of a plumber.
Choose a plunger with a rubber flange to ensure a better seal. Before using a plunger, add dish detergent to the water in the bowl. This makes it easier for the clog to slip through the pipes. If the liquid in the bowl is near the rim, give it a few minutes to drain to prevent overflows. If the water has all drained, add more so that it covers the bell of the plunger.
Place the plunger in the bowl, directly over the drain. Press down on the handle slowly to prevent splashes due to the air in the bell. Pull up on the handle to fill the bell with water and provide suction to loosen the clog. Once the bell is full of water, use a vigorous in-and-out motion to eliminate the clog.
A toilet auger is a special type of plumber's snake that has a bent tube to help make the first turn into the toilet trap and protect the porcelain fixture. Insert it into the clogged toilet, and turn the handle with a forward motion. When it clears the clog, the toilet flushes. Remove the auger, and try flushing again to ensure the line is clear.
