Skip to content Using a plunger is the best way to try to unclog your toilet. Make sure to turn off the toilet’s water shut-off valve before using the plunger. This will prevent accidental flushes, which can lead to an overflow. Once you have the water turned off, you’re ready to unclog the toilet. The rubber end of the plunger should be soft, flexible and have no cracks. To unclog, place the rubber end of the plunger over the clog and push down with a fair amount of pressure. The clog should eventually break, allowing the water to drain. If this does not fix your problem, contact a professional plumber for further help.
