“What is this metal thing in the toilet at my work?

It sounds like you’re describing a metal object in a toilet, but the exact identification depends on its shape and position. Here are the most common possibilities:

Flush Sensor or Plate

Many public toilets have a metal flush mechanism, either a sensor plate or a manual push plate.

Usually flat, rectangular, or circular, sometimes with a button.

Toilet Tank Lever or Handle Mechanism

In older or industrial toilets, you might see a metal rod or arm that connects the flush handle to the valve inside the tank.

Water-Saving Device (Fill Valve Insert or Flow Restrictor)

Some toilets have metal inserts in the bowl or tank to regulate water flow for efficiency.
