How to Fix a Leaky Toilet

You just might have a toilet with a slow leak and not even know it. But that leak is costing you extra money on your water bills and wasting a valuable resource.

To check your toilet to see if it has a leak, lift the tank lid and add a few drops of food coloring to the water. After an hour or so, if the color has seeped into the bowl, you know you have a leak.

The cause is probably in the flapper valve, or the valve opening that empties water from the tank into the bowl. Check for any cracks that you may find in the flapper, or debris around the valve opening, to ensure there’s a nice, tight seal there.

If cleaning the valve seat and flapper doesn’t stop the leak, pick up a replacement kit for a few dollars. It’s a lot less expensive than the water that’s being wasted.


  1. wrong, it is not done – i have changed the flapper – it no longer flushes itself at night but when i put the food coloring in the tank the coloring comes out in the bowl, what now brown cow?????? do i need to get a new pot???
