Before you can replace your toilet handle, you need to choose a new one. The part you’re looking for is called a toilet trip lever, and it includes the exterior handle as well as the lift arm that goes inside the tank. Check your existing toilet tank to see where the handle is located, whether it’s on the front, side, or at an angle. Some replacement handles will be designed for specific mounting positions, while others will be universal. Make sure you choose a handle that’s compatible with your toilet tank’s handle mounting position. Use the brand name and model number of your toilet to find one that is compatible.
If you’re not sure what kind of replacement toilet handle to buy, put off this step until you’ve removed the old handle. Then you can take the old handle with you to the hardware store and ask an employee to help you find a replacement that will fit your toilet.
