Suction bell (sanitary engineering)
A suction bell (officially also known as drain tampers , rubber suction cups and sink cleaner , but usually only known under a multitude of regionally different colloquial and dialect expressions such as plunger ) is a household appliance that removes blockages in drains (sinks, toilets, bathtubs, sinks ...) serves. It consists of a rubber bell, which is usually located at the end of a wooden stick, and which can be used to clear blockages in siphons by creating both positive and negative pressure with it .
The conical suction bell is sometimes used without the wooden handle as a mute for the trumpet and trombone.
application
With the suction cup is alternately a lower and pressure generated in the drain to solve fixed supporting material and wash away. The open bottom of the suction cup is placed on the drain and depressed. The rubber lip should be as close as possible all around. This is often not achievable in toilet bowls, so cleaning spirals have to be used here.
In sinks with additional drainage openings (such as an overflow), the effect is significantly increased if these are sealed, for example by pressing a wet washcloth in front of them.
Then enough water is filled into the basin that the clogged drain is flooded when the rubber bell is briefly raised. There should be as little air as possible under the suction cup and in the drain, since the compressibility of the air reduces the acceleration of the water column . With a quick up and down movement of the wooden stick and the suction effect of the bell, the blockage can be loosened or loosened and the solid bodies responsible for the blockage can be transported into the drainage pipes with a larger cross section and washed away.
The rubber material of old suction bells often became hard and brittle, so that adequate sealing could no longer be achieved.
Alternatives
The use of a suction bell is relatively simple and hygienic.
Sometimes, however, larger deposits of grease or other plastic or solid matter, as well as stuck hair or other fibers cannot be completely removed with the suction cup.
In this case can
- a pipe cleaning spiral can be used to loosen the stuck deposits,
- chemical pipe cleaner is added to the drain to first dissolve organic matter before the suction cup is reinserted,
- the siphon or the drainage pipes are pulled apart or screwed to clean them.
Plastic pipes are easier to dismantle than the cast and sheet metal pipes used earlier, the connections of which often got stuck and could only be loosened with tools.
Trivia
In his drawings (in the star ), the cartoonist Tetsche - alongside other trivial things that are typical for him, such as fried eggs , molars , etc. - often includes a "plump". An oversized plunger is mounted on the roof ridge of his house. Tetsche repeatedly claimed in interviews that the symbolic meaning of the suction cup for his work was explained by the fact that he was born with the plunger: “I was born with a suction cup. My father was a plumber, so it was obvious. You did everything yourself back then. "
