How to Determine Your Toilet Flapper Replacement Size:

 Step 1: Remove tank lid

Take the tank lid off of the tank and put in a safe place to avoid accidentally breaking it.

Step 2: Turn off water supply

The water supply valve is normally located on the wall, on the left side of the toilet as you are facing the toilet. Turn the handle clockwise to turn off the water. If the valve will not completely turn off, you can still proceed because it will not effect this simple replacement of the flapper.

Step 3: Remove the water in the toilet tank

If you would like to conserve the water in the tank, then use a small cup to scoop the water out and pour it into a larger container or bucket.

This water can then be used to water your plants. Otherwise, flush the toilet to remove the water in the tank. Since you already turned the water supply valve off, no water will be filled back into the tank and you’re ready to remove the flapper. The water does not have to be completely removed, as long as it’s just below the flapper. When you remove the flapper, any water left inside the tank will exit the tank anyway.

Step 4: Determine your current flapper size

Measure the width of the top of your flapper with a ruler or tape measure.
