Does the sewer pipe in the kitchen sink smell bad? What should we do?

This is mainly because there are too many bacteria and oil stains in the pipeline, which gives off a burst of smell. At the same time, the pipeline is not sealed, causing the smell to overflow. The following methods can be used to remove odor:

1, use kitchen and bathroom pipes to remove odor particles, or use grapefruit peel to boil water, warm it and pour it in to clean up the residual smell.

2. Seal the mouth to prevent odor, and replace the upper hose with a U-tube.

Sewer dredging method

1, channel dredging agent: it is the best product on the market at present. This product is especially effective for removing the blockage caused by hair, greasy and paper. Widely used in restaurants, hotels, families and other vegetable sinks, wash basins, bathtubs, floor drains, toilets and other blockages. Do not damage the sewer pipe (including PVC pipe) and electroplating layer.

Usage: Clear the accumulated water in the washbasin or sanitary ware, and pour 50-100g of this product into the sewer. If there is no water in the sewer, please add half a cup of clear water. At this time, the pipe is boiling. After about 20 minutes, rinse with plenty of water.

Recommended dosage: washbasin, bathtub, floor drain-100g, vegetable sink-200g, toilet-400g.

2. The practice of clearing the blockage of the bathtub sewer is mainly caused by the hair left in the shower. Because there is a cover at the drain of the bathtub, it can only be dredged from the floor drain. Buy a hand-cranked spiral steel wire (about 6 mm in diameter), push it down from the floor drain while shaking it until you feel something foreign, and then gently pull it out while shaking it. Clogged hair and other dirt will rotate on the spiral steel wire and the problem will be solved.

It will be more convenient if the drain in the bathtub has no cover (hydrochloric acid should never be used, for one thing, it will pollute the environment, for another, it will easily cause danger to human body, and for another, the pipeline will be corroded by hydrochloric acid for too long, which will make the trouble even greater).

3. Put caustic soda into the sewer, and then pour a pot of boiling water into it, not a thermos bottle, but a large pot of water.

4. If you have poured water in an iron pan and invited iron branches to pass through, but the water has not been removed later, it is not suitable to use iron branches again to avoid the corrosion of the canal being penetrated.

It can be replaced by thick rattan. Ten eight-inch nails can be nailed to the rattan head, and the impurities are loosened while being put in, then the concentrated alkali solution is poured in, and then the rattan is pushed out. If this continues many times, it will have an effect. In addition to thick vines, you can also buy spring channel openers from hardware stores, which is more effective. Salt, white vinegar, straws, etc. Being used by ordinary people can't work.

5. Get some baking soda and vinegar.
