What simple machine is the flush handle?

Answer 1

A hand pump is not a simple machine. A simple machine is the lever, pulley and screw also might include the wheel and axle, wedge and inclined plane.

A hand pump would have some valves for lifting the water.

Answer 2

Mechanical hand pump?

only a lever (on the fitting to seal around the valve stem.)

not simple machines:

there is a compression chamber

there is a plunger with a handle on one end, and a gasket on the piston inside the compression chamber

the nozzle itself on the end of the hose

there is a ball check valve to permit air flow in only one direction

the whole mechanism works like a pneumatic lever to amplify the pressure over the piston (which might be an inch across) into a small area of the nozzle. That is an outside the box answer.

electric pump has more (like the piston rod would be a lever), and a bellows type (foot pump that looks like the thing you blow onto a fireplace) would have more also.
