Remove the cover of the toilet, and place on the toilet seat.
Locate the flapper ball inside the tank of the toilet. The flapper ball is an inflated ball that is attached to a long rod and a chain.
Unclip the chain from the flapper ball. The chain is secured to the flapper ball using a small clip that is easily unhooked.
Shorten the chain by folding a few links over and replacing the clip on the chain. Replace the lid to the toilet tank.
Test the toilet valve to see if it’s working properly by flushing the toilet. If need be, shorten or lengthen the chain until the valve is where you would like it.
