How to change the toilet on the second floor into a separate sewer? Does the toilet on the second floor have anything to do with the upstairs?

1. First, to determine whether the change can be successful, it can only be carried out if the property permits. At the same time, if the first floor is also a residence, it is necessary to obtain the consent of the residents on the first floor, and then put forward the construction method according to the site situation and prepare the materials, including PVC drainage pipes and corresponding components.

2. Then dig the place where the layout is connected with the sewage pipe, cut off the water first, cut off the connection between the toilet drainage pipe and the main drainage pipe, and block the interface at the same time. Then, for the bathroom on the second floor, the drainage pipeline is arranged along the corner, and the previous horizontal pipe connection needs to be trenched in advance to ensure a certain depth and slope.

3. After all the pipes are connected successfully, don't rush to seal the ground. The drainage test can be carried out first to ensure that the drainage pipeline is unobstructed, and then the ground can be backfilled. Just lay waterproof material on the ground, and then lay tiles.

Does the toilet on the second floor have anything to do with the upstairs?

If the toilet on the second floor is blocked, it is likely to be directly related to the blockage of the drainage pipe upstairs. But some of them are irrelevant, because we still have to consider whether the drain pipe under the toilet on the second floor is blocked. If there is a blockage, it is directly related to the drainage pipeline upstairs.

But if the horizontal pipe and the toilet itself are blocked, it is your own reason and you need to clear your toilet. If there is congestion, we need to find out what the reason is before we can divide the responsibility.
