Causes of sewer blockage

The problem of sewer blockage generally occurs in kitchens and bathrooms. These places use a lot of water, and there are garbage such as dust, grease, paper and cosmetics, which are easy to adhere to the inner wall of the pipeline and form a blockage. The following are some specific reasons for sewer blockage.

1. Grease enters the drainage pipe: Grease, detergent and food residue used in the kitchen may be deposited on the inner wall of the drainage pipe, which will lead to blockage of the drainage pipe over time. Especially in the kitchen where the range hood is often used, a large amount of carbon monoxide and grease will be produced, which makes the pipeline particularly easy to block.

2. sundries enter the pipeline: garbage, paper, plastic bags, shoes and socks and other sundries enter the pipeline, which is easy to get stuck in the middle of the pipeline, causing the drainage pipeline to be blocked. In addition, often not cleaning the filter screen of the washing machine or directly throwing impurities in clothes into the washing machine will also make these impurities jam with the water rushing to the water meter.

3. pipeline aging damage: the drainage pipeline has been used for a long time, which may lead to blockage of the drainage channel due to pipeline aging damage. Usually, this reason is caused by the design problems of residential pipes.

4. Improper use: cigarette butts, sanitary napkins, wet tissues, etc. Often thrown into the toilet or sewer at will, resulting in a lot of garbage and dirt in the pipeline, which is also easy to cause sewer blockage.

5. The drain is blocked: the drain is easily blocked or stuck by sundries, especially in crowded places, such as hotels, restaurants and shopping malls. This can prevent water from flowing out, causing flooding, sewage backflow, and even serious flooding.

6. Municipal pipeline problems: In some cases, problems appear on municipal pipelines, which may be caused by pipeline rupture, improper design and lack of maintenance. This situation needs to be checked and maintained by the municipal department.
