Plunger

A plunger is a device driven by or against fluid pressure.[1] In plumbing, the term plunger commonly refers to handheld tools used to clear blockages in drains and pipes. Plumbing plungers consist of a rubber suction cup attached to a stick (shaft) usually made of wood or plastic. A different bellows-like design also exists, usually constructed of plastic. Alternate names for plumbing plungers include force cup, plumber's friend or plumber's helper.[2]

Plumbing plunger

In musical performance, tools called plungers are used to mute trumpets and trombones. A plunger may also refer to a component of a device that generates fluid flow, such as in a medical syringe or a French press coffee brewer.

History edit

The plumbing plunger was invented in 1874[3] by New York confectioner[4] John Hawley, with the flattened rim added in 1876.[5] The invention is referred to in the patent as a "vent-clearer", and was marketed as a "force cup".[6]

Applications edit

Plumbing edit

Use edit

For the common plunger, the cup is pushed down against the drain opening, either pressing hard into the drain to force air in, or pushing down until the rubber cup is flattened, and is then pulled out, creating a vacuum to pull blockage material upward and dislodge waste or other material.

Shape and function edit

The cup of a kitchen plunger looks like a rubber ball cut in half with a flared edge, while the toilet plunger's cup looks more like a distorted bowl, tapered on one half, with a large opening on the bottom.

A plunger is much more effective with water in the pipe, as water does not compress and thus transmits more of the applied force than does air.[7] When a plunger alone is ineffective, it can be supplemented by a chemical drain cleaner for sinks and tubs; or a plumber's snake for stubborn clogs, and clogs of the main line or toilet.[8]

Syringes edit

In syringes, plungers are constrained to linear motion as they are pulled and pushed within an outer tube or barrel. The plunger allows the syringe to take in or expel fluid through an orifice at the open end of the barrel. In disposable syringes, the plunger is often made of plastic with a rubber tip to seal between itself and the barrel.
