If your toilet overflows, it can be a stressful and unpleasant experience. Here are the steps you can take to get the situation under control:

1. Do not flush again: If water is rising in the bowl immediately after you’ve already flushed, that means a clog is blocking the water from moving through the toilet drain. If you flush again, there will be even more water that’s unable to make it past the clog, and you’ll end up with even more flooding from the toilet bowl.

2. Turn off the water supply: Locate the water shut-off valve near the base of your toilet and turn it clockwise to stop the water flow. If your toilet does not have one, open the tank and rig the float to stay in its position and not let any more water fill the tank.

3. Find the flapper inside the toilet tank: Locate your flapper at the bottom of the tank. It will look like a rubber circle attached to a chain or metal lever. Push the flapper closed. When the flapper shuts and seals against the bottom of the tank, this will stop water from flowing into the bowl.

4. Secure the float: A float cup or float ball sits on top of the water in the toilet tank. Tie up or rig the float so it can no longer move, and water cannot continue to fill the tank.

5. Remove the clog: Put on some rubber gloves, and use a flange plunger to dislodge the blockage. If plunging the toilet will cause it to overflow or splash over the bowl’s sides, scoop out some of the water with a cup or bucket to make room for the plunger. If a plunger doesnt work, try using a plumbing snake.

6. Clean up the water: Use towels to clean up a small amount of water or a wet/dry vacuum to help with larger spills or to soak water out of carpet and other fabrics. Disinfect and clean the affected area immediately.

Its important to note that if youre not comfortable or able to handle the situation, its best to call a professional plumber for help.
