What to Do When a Toilet Overflows

how to stop water in toilet from overflowing
  1. Locate the shut-off valve.
  2. Turn the valve clockwise to the closed position.
  3. If shutting the valve doesn't do the trick, then reach inside the tank and press down on the flapper to create a seal. Hopefully, that does the trick until you can unclog the toilet and flush everything down.
  4. If pressing down on the flapper doesn't do the trick, try manually raising the float ball/cup on the fill valve.

If the flapper/float tricks don't work either, you're going to need to shut off the main water supply to the house (and fast). A broken shut-off valve is more common than you might think. They sit open for months or years without any movement, and they deteriorate. Test them and replace them as needed so you can avoid an emergency like this.

Now that the toilet is no longer overflowing, you're still going to need to know how to plunge a toilet, or maybe you need to know what to do if you don't have a plunger.
