Sewer is a very common thing in our life. It plays a role in discharging the sewage produced in our home life. However, in the process of use, some people often pour solid things into small waterways. Over time, small waterways are often blocked, causing a lot of inconvenience to our life. What should we do when small waterways are blocked?
How to dredge the sewer? Method for dredging sewer
1、 Methods of dredging the blockage of bathtub sewer: (mainly caused by the blockage caused by the hair left during bathing). Because there is a cover at the water outlet in the bathtub, it can only be dredged from the floor drain. Go to the small store to buy an 8 yuan hand-operated spiral steel wire (about 6mm in diameter) and push it downward from the floor drain until there is a feeling of foreign matter in the hand. Then gently pull it up while shaking. The blocked hair and other dirt will spin on the spiral steel wire. The problem is solved. Very convenient. If there is no cover at the water outlet in the bathtub, it is more convenient. (do not use hydrochloric acid. Firstly, it pollutes the environment. Secondly, it is easy to cause danger to human body. Thirdly, the pipeline with long service life is easy to be eroded and perforated by hydrochloric acid, which is even more troublesome)
2、 Put caustic soda into the mouth of the sewer, and then pour in a pot of boiling water. It's not a warm pot, it's a big pot of boiling water.
3、 If you have poured water and asked workers to use iron branches to pass through, but then do not go to water, it is not suitable to use iron branches again, for fear that the anti-corrosion canal will be penetrated. Thick rattan can be used instead. The rattan head can be nailed with ten or eight inch long iron nails. One side extends into the rattan and the other side rotates and stirs to loosen the sundries, then pour in with concentrated alkali solution, and then push and pull the rattan out. If it continues for many times, it will be effective. In addition to the thick rattan, you can also buy a spring Channeler from the hardware store, which has a better effect. The salt, white vinegar and straw used by ordinary people can't work.
4、 Waterway dredging agent: it is the best product in the market at present. This product is especially effective in unblocking the blockage caused by hair, greasy, paper, etc. It is widely used to unblock the blockage of vegetable washing pool, washbasin, bathtub, floor drain and toilet in restaurants, hotels and families. Do not damage sewer pipes (including PVC pipes) and electroplated coatings.
Usage: remove the accumulated water in the washing basin or sanitary ware, pour 50-100g of this product into the sewer. If there is no water in the sewer, please add half a cup of clean water. At this time, the pipeline is boiling. After about 20 minutes, flush with plenty of water.
5、 Washing powder and hot water: pour 1 cup of washing powder into the blocked sewer, and then pour 3 cups of hot water. If this doesn't clear the sewer, pour another cup of vinegar into it. This method is still very good, convenient and effective.
6、 Ask professionals: if the above methods still can't solve the problem of dredging small waterways, we should ask professionals to dredge the sewers.
