How to repair a running toilet suffering from "phantom flushing"

Is your toilet frequently or even just occasionally running at random times? Do you hear the tank briefly refilling with water even though you didn't flush it? This is often referred to as "phantom flushing" and chances are your flapper needs to be replaced. This video explains how to that, and why the Korky brand of flapper is superior to the Fluidmaster 540 flappers with the problematic white silicone rings.

Thank you, your video helped me. I was going to replace the whole gasket connecting the top tank to the bottom but this solved my issue without having to do that. I got the Korky instead of the Fluidmaster as you suggested.

How come you don’t have a floating attached to the chain between the lever and flapper? Don’t we need it?

Not needed for this type of setup.

Search Amazon for 'Korky 3060BP' - it looks like you can buy it for half that much on a different listing on Amazon.
