How to rebuild the sewer of an old house

The sewer of an old house is a very important part of house life. It is the core to ensure family health to discharge the wastewater in the house to a sewage treatment station or septic tank. However, with the evolution of history, sewer problems in many old houses began to appear. These problems include aging, leakage, burst and blockage of sewer pipes, which seriously affect the living environment and health of houses.

Here are some ways to transform the sewers of old houses:

1. Replace the sewer pipe

If the sewer pipe is aging, leaking or bursting, it needs to be replaced. First, we must find the location and direction of the sewer, and then dismantle the original sewer and install a new sewer. The new sewer pipe should adopt reliable and durable seamless steel pipe or UPVC pipe.

2. Improve the sewer system

For the poor sewer system, it is necessary to find ways to improve the sewer system, adjust the direction and position of the sewer, and try to improve the drainage effect. In addition, ensure that each outlet is equipped with an insect-proof and odor-resistant tap water sealer.

3. Clean up the blocked sewer.

If the sewer is blocked or poorly drained, it needs to be cleaned in time. Cleaning methods can be mechanical cleaning and chemical cleaning. Mechanical cleaning generally adopts high-pressure water or drain pipe cleaning machine, which can effectively remove debris and dirt from sewer mouth. But if the blockage is serious, it needs to be cleaned with chemical cleaning agent.

4. Add waterproof isolation layer

If the sewer is located in the basement or low-lying place, it will often be affected by groundwater and accumulate water. The method of laying waterproof isolation layer on the external wall foundation or ground can be adopted.

To sum up, around the guiding principles of drainage system and the requirements of installation and maintenance, the positions of pipes and drainage pipes should be arranged reasonably, the length of pipes should be shortened as much as possible, and good materials and techniques should be adopted to ensure that the drainage pipes have good drainage and deodorization effects. At the same time, through regular cleaning and maintenance, the service life of sewer pipes can be extended.
