How to install a toilet handle
Lift the lid off of the toilet tank and make sure the tank is empty.
If the toilet has been in use previously, shut off the water supply to the toilet, then flush it to empty the tank. If this is a new toilet, do not turn on the water supply until after the handle is installed.

(a). Cut the toilet handle in half, then make the cut with a utility knife. It is very important to clean the toilet handle until all traces of dirt, dust and oils have been removed. (b). Loosen the screw holding the lid to the toilet tank. Make sure not to hold it locked as this can cause it to slide off of the toilet tank and could result in injury. (c). Hold the handle in your non-dominant hand and remove the gasket and shank nut from the back of the handle. The gasket is a rubber ring that sits behind the nut and helps to seal the handle from leaks. (d). Find and sand the toilet handle surface, using a shredding or sand-cutting grinder. To build the handle, you will need a level, concrete surface to work on.
(c).
