The trick of sewer dredging.

1. Now there is a special waterway dredging agent on the market, which is particularly effective for dredging blocked water pipelines. It is often used in some restaurants and hotels. When in use, the accumulated water in the sanitary ware is cleaned first, and a proper amount of waterway dredging agent is poured into the blocked sewer pipe. If there is no water in the pipeline, pour half a cup of clear water into it, wait for about 20 minutes, and then rinse it with plenty of water.

2. If the sewer is blocked due to the accumulation of hair, you can buy a manual spiral steel wire in the market, push it down from the floor drain, shake the spiral steel wire when encountering foreign objects, and slowly pull it up, so that foreign objects such as hair blocked in the pipeline will be taken out by the spiral steel wire.

If the oil in the kitchen sewer is blocked, you can pour boiling water into the sewer until the oil dissolves slowly. In addition, you can also use 20% soda water to dredge oil pollution.

4. Find a bamboo pole or log with a diameter similar to that of the blocked sewer, pour a certain amount of water into the pipe, then insert the bamboo pole into the sewer pipe and twitch it up and down continuously, so that the foreign bodies blocked in the water pipe can be washed down quickly under the pressure in the pipe.

Another way is to buy caustic soda in the shop, put it in the sewer, and then pour boiling water into it.

6. If there are hard objects such as cement in the water pipe, it can be dredged with hydrochloric acid. In stores, we can generally buy 35% hydrochloric acid, and add a small amount of flour when using it to slow down the corrosion of hydrochloric acid. Reduce the damage to sewer pipes.

7. Finally, if you can't solve the problem by blocking yourself with hard objects, or you don't want to do it yourself at all, the easiest way is to call the property management company or a special pipeline dredging company, and they will have a better way to help you solve it.
