Flushing your toilet is one of those things that you do pretty much without thinking about it, but probably not if you have a handle that is having issues. Some have a handle that is loose or wiggly, others have one that doesn’t work half of the time, while others just have an old, ugly, or broken handle that they would like to get rid of. Fortunately, you might be able to fix the problem yourself without too much effort.
Most toilets have fairly standard handles, basically just functioning like a lever that is connected by a chain to a flapper at the bottom of the tank that lets the water out. Being that it is such a simple design, replacing a handle can be done in just a few steps.
Naturally, you should first make sure that the water supply is turned off to prevent a major disaster. Next, you can disconnect the chain between the lever and the flapper.
Removing the old handle is usually just a question of removing the nut that holds it in place inside the tank. Make sure you get the chain the right length so that the flapper will close and open completely. If the chain is too short you will end up with a toilet that is constantly running. Your next step is to do everything in reverse to finish the job.
