    Since you’ll be adding more water to the toilet bowl in just a second, it’s important to stop the flow of water into the bowl. Reach behind the toilet near the floor and turn the valve in a clockwise direction. If the valve is stuck, use a little bit of WD-40 to loosen it up. [1]
    • After you’ve unclogged your toilet, simply turn the valve counterclockwise to turn the water back on.

    Turn your stove on high heat and place a water-filled pot onto the stove. Cover your pot with a lid and wait until the water heats up, but don’t let it boil (this should take about 5 minutes). If the water starts steaming or it gets above 120 °F (49 °C), it’s time to take it off the stove. [2]
    • Pouring boiling water into the toilet can crack the wax ring around the toilet or even the toilet bowl itself. Get your water hot, but don’t let it boil. [3]
    • If you’re worried about getting your water too hot, just use hot water from the tap.

    Pour gently and make sure the water doesn't pass the rim. Be careful not to spill any to avoid burning yourself. If the clog is minor, the hot water may be enough to loosen it up all the way. [4]
    • Depending on how clogged your toilet is, you may have to pour a little water in, stop, and then wait for the water to go down before pouring the rest.

    The dish soap will float to the bottom of the bowl because it is heavier and denser than water. Don’t be afraid to use too much—in this case, the more the better. [5]
    • Use grease-fighting dish soap to break up the clog.

    After a few minutes, the soap will work to dissolve the clog at the bottom of the bowl. [6] You might even start to see the water level lower a bit, which is a good sign! [7]
    • If the soap doesn’t do much in terms of unclogging your toilet, don’t panic—there’s one more step that will hopefully flush all your problems away.

    Fill another 1 gallon (3.8 L) pot with hot water and place it onto the stove to get hot, but not quite boiling. If you don’t want to wait, just use the hottest water from your tap instead. [8]

    After about 2 to 3 rounds, flush the toilet to check if the clog is gone. Be sure to give each 1 gallon (3.8 L) of hot water about 20 minutes to settle. [9]

    Plunge your toilet if it's still clogged. Even if you've already tried to plunge the clog, dish soap can weaken it, so it's always worth a second shot! Place the plunger into the bowl directly over the hole. Press down sharply in short, fast strokes, and be sure to lift sharply to create suction. After 4 or 5 full strokes, lift the plunger on the last upward motion. [12]
    • Run the plunger under hot water for 30 seconds before plunging to warm the rubber up.
    • If the clog still doesn't come loose, call a plumber.

    You can put plenty of detergent in the toilet bowl. It will break up the toilet paper and other things blocking the toilet. This method may take some time to work.

    Get a plunger or a toilet drain snake and use them to unclog a toilet. These are the most effective and quick means to clear the clog.

  • Question
    Can it be warm water instead of boiling water?

    Community Answer
    It could be warm water, but that might not work as well as boiling water. The boiling water would be a better choice.
