What is a plunger or force cup?

A plunger, or force cup, is a tool typically used for clearing clogs in Plumbing fixtures like sinks, toilets, and drains. It consists of a rubber suction cup attached to a long handle, allowing users to create a vacuum seal and apply force to dislodge blockages. When pushed and pulled, the suction generated helps to break up or dislodge debris causing the blockage. Plungers come in different designs, with some specifically tailored for toilets or sinks to maximize effectiveness.
