We’ve all had that moment of anxiety when a toilet is about to overflow and you feel helpless to stop it… You question your decision to flush it twice when the first one didn’t do the job and you realize it was a mistake as water reaches the rim. A cool head and quick action can avoid disaster if you know what to do. Remove the tank lid and look for the hinged, rubber flush valve at the bottom. It is suspended by a chain from a rod connected to the flush handle. Simply close the valve by hand to stop water from entering the bowl. Practice this when there isn’t an emergency and then you’ll know just what to do the next time an overflow is imminent.
