How to connect the wall-mounted toilet, does it have to be connected to the main pipe?

Wall-mounted toilets are more and more popular with everyone. The benefits can be summarized in three points: one is good appearance, the other is easy to clean, and the third is to solve the problem of long-distance toilet displacement.

Owners often ask how the wall-mounted toilet should be connected, shouldn’t it be connected to the main pipe? Why is my house connected to the original toilet sewer, is this okay?

Today, I will focus on the problem of connecting the wall-mounted toilet.

There are two ways to connect the wall-mounted toilet. The first one is to connect the main sewer pipe, and the second one is to connect the original toilet sewer pipe. Which one to choose depends on the actual situation of the bathroom.

There are two typical cases. The first is that the sewer pipe and the wall-mounted toilet are on the same line, and there is no obstacle between them. In this case, the priority is to connect the sewer pipe to the main pipe. The advantage is that there will be a section of pipe between the wall-mounted toilet and the main pipe, and this place must be designed in advance.

The second situation is that the wall-mounted toilet and the main sewer are in a vertical direction, and there is a flue or other wall obstruction in the middle. Although their straight line distance is very close, it is impossible to connect the main pipeline in this case. In the case of a wall-mounted toilet, it is necessary to connect the original toilet sewer.

In addition to these two cases, there is also a special case where the position of the wall-mounted toilet is equivalent to the position of the main downpipe and the original toilet downpipe.

In this case, many owners are more entangled, how to connect?

This situation is also a good decision. Try to consider using a 11 cm round pipe instead of a flat pipe for the toilet water pipe. Then we will see which of the two situations can use a round pipe.

Summary: The wall-mounted toilet can be connected to the main pipe or the original sewer pipe, as long as the pipe path is well designed, there is no problem. The principle to follow is that the pipe should be short and the diameter of the pipe should be large.
