How to rebuild the sewer on the second floor and how to rebuild the independent sewer on the second floor?

2. If there is a problem of anti-water in the sewer downstairs, it is mainly caused by blockage, because 1 building is an independent sewer, and the sewer pressure is relatively low, so it is not easy to be blocked. The second floor is the most prone to waterproof blockage, so the sewer pipe on the second floor can be reformed, which can effectively avoid the recurrence of waterproof problems.

In the concrete transformation, a vertical elbow can be added and installed upward, which can effectively solve the problem. The elbow can change the direction of the water pipe, depending on the angle, some are 45 degrees, some are 90 degrees or 180 degrees, so this 90-degree elbow is selected. Then match according to the diameter of the pipe. During the renovation, remember to coat the interface with PVC glue to avoid water leakage.

You can also install a check valve at the toilet mouth, including a vegetable sink and a washbasin, to avoid the problem of water reflux.

How to change the independent sewer on the second floor?

1. Block the original sewer pipe, and the sealing performance must be good.

2. pry open the bathroom tiles and cut a hole.

Put the pipe into the hole and connect it to the sewer. Need to be sealed to prevent water leakage.

4. Lay bathroom tiles and cover the hole.

What about the sewer going against the water?

There is a problem of anti-water in the sewer. First of all, we need to check what causes it. The pipeline may be blocked, and the residents of 1 building may be independent sewer pipes, which has nothing to do with 1 building. It may be that my home did not drain water according to the regulations, which led to the problem of congestion. First of all, we need to solve the congestion, please ask professionals to come to the door to deal with it.

Sewer pipes can also be modified. For example, the sewer of 1 building also appeared anti-water, requiring the property to change the sewer pipe into an independent one. You can also install a check valve, or install a manual master switch in the kitchen and bathroom to prevent the check valve from failing.

What should I pay attention to when changing the bathroom to sewer?

1. When the pipeline is diverted in the bathroom, it is necessary to pay attention to the position of the connection interface, and its tightness must be good, otherwise it will be a matter of time before water leaks. Before sealing, all stains in the interface area must be cleaned up, and then waterproof glue should be applied.

2. When the sewer pipe is connected, a certain inclination angle should be made to ensure that the inlet pipe is slightly higher to prevent the water source at the entrance from being polluted. Under normal circumstances, as long as the inclination angle will not affect the aesthetic effect of floor tile paving, it is ok.

3. The specifications of the sewer pipe should also be confirmed before the pipeline reconstruction. The length of the independent pipe used in the bathroom should not be too long, otherwise it will affect the normal water flow speed, and it is easy to block the pipe and increase the difficulty of later maintenance.

4. After the sewer pipe is fixed, check the irrigation to ensure that the pipe will not leak. If there is nothing wrong with the pipeline inspection, it can be blocked. Only by considering these details can we ensure the normal use in the later period.
