The siphon as an odor trap
The U-shaped piece of pipe below the sink or wash basin is known as the siphon . Every time you turn on the faucet, this pipe fills with new water that remains. As a result, the siphon forms a natural barrier against odors from the sewer system . Nevertheless, it happens again and again that food residues, washing-up liquid and grease are deposited in the siphon and clog the drain. You can then remove the deposits from the drainpipe yourself using simple means.
Mechanically clean the clogged sink
The suction bell
One way to clean the drain is with the suction cup. It is also called pümpel or pömpel . First, let some warm water and detergent run down the drain. Then place the suction cup on the drain so that it is completely covered. Then put a little water in the sink. Then move the wooden handle up and down quickly. This creates a vacuum with a suction effect, which loosens the deposits in the siphon . Then loosen the plunger and rinse. Attention: When removing the suction bell, wastewater can splash out with it!
The drainage spiral
The siphon can also be cleaned with this tool. Insert the coil into the drain and gently operate the crank to loosen any debris . Then rinse thoroughly with water.
Use home remedies
Baking soda and vinegar
These two ingredients from the kitchen are real all-rounders. Baking powder not only makes the cake fluffy, it also loosens dirt . In combination with vinegar, you can use it as a drain cleaner. Pour three to four tablespoons of baking soda down the drain and immediately add half a cup of vinegar . You will then hear a bubbling noise – the deposits are loosening. When the effervescence has stopped, rinse with hot water.
If you still have some leftover cola at home, you can also use the soft drink to clean your drainpipe. Pour about a cup of cola down the drain and let it sit overnight. Rinse off with hot water the next morning.
Use chemical or biological drain cleaner
In addition to home remedies, there are chemical or biological drain cleaners. The biological products use microorganisms or enzymes, which is why they are much more environmentally friendly and harmless than chemical cleaners. If your sink is clogged, pour the prescribed dosage down the drain and leave the product on for as long as noted on the packaging. The duration can be between 30 minutes and several hours. Then rinse thoroughly. Since chemical agents, in particular, are highly corrosive, please observe the respective safety instructions.
Open the siphon and clean it
If the mentioned means do not help, you can clean the siphon manually. The U-shaped pipe section can be unscrewed by hand or with a pair of pliers. Before doing this, clear the cabinet below the sink and place a bucket under the siphon to catch the excess sewage. Once you’ve unscrewed the piece of pipe, you can clean it in another sink using water, detergent, and a brush. Then fix the siphon correctly again so that it is tight. And then the water flows again and the unpleasant smells are eliminated. By the way: did you know that lots of ingredients from your kitchen are suitable as cleaning agents?
