Toilet Handle Won't Flush | Homesteady
The handle is the outer component, but directly on the other side of the tank's front wall is a flush lever, which is connected to the handle. When you press the handle down, one end of the flush lever rises, helping start the flush. Often you can diagnose a broken flush lever by simply looking at the handle. If a handle that normally sits horizontally has now fallen into a vertical position, the lever is likely broken, although this handle position could also mean that you simply need to tighten the nut on the back of the handle. If the flush lever is broken, install a new flush lever with a new handle attached to it.
