What is the leak hole off the wall tile in the bathroom flush toilet?

One, if the "leak hole" in the question refers to the floor drain, then the answer is:

1) Reserve according to the design drawings;

2) When designing by yourself, it should be kept above 25cm with the wall.

Second, if it refers to the reserved place of the sewage pipe of the toilet, the answer is as follows:

1) According to the construction of engineering design drawings, it is recommended not to change it easily;

2) In the case of self-design of your own house, the sewage pipe under the toilet is generally not less than 40cm (cm) from the wall behind the toilet, and it is best to buy the toilet back in advance, and the actual measurement distance is the most practical for beginners.

There is a reserved opening at the bottom of the toilet bowl that connects with the sewage pipe. There is also a concealed, sealed back-up opening. These two outlets are used to adjust the distance to fit the sewage pipes on the ground.

1. There are three possible causes of water leakage around the floor drain: 1. If the glue at the pipe joint (elbow) causes water seepage, you can wrap the upper end of the pipe with a dry cloth and wipe the pipe clean to see the joint. Workaround:

After the pipe is completely dry, the pipe is tightly covered with glass glue. 2. The cement around the floor drain is not tightly sealed. Workaround:

Kick off the cement within 200mm around the floor drain and repair it with a special plugging spirit. 3. If there is a problem with the overall waterproofing of the bathroom, the only way to do it is to completely redo the waterproofing. Second, the flush toilet leaks:

First of all, the reasons for the leakage of the toilet base should be analyzed, generally speaking, the reasons for the leakage of the toilet base are mainly in the following aspects: 1. The sewer pipe is blocked, and the water may overflow from the lower part, in this case, the toilet needs to be dredged; 2. There is a leak in the water storage place of the toilet, so it flows to the ground and sits down, and there is a leakage. It is necessary to use glass glue or cement to re-strengthen the surrounding area; 3. Same as the cause of floor drainage, if there is a problem with the overall waterproofing of the bathroom, the only way to do it is to fully redo the waterproofing.

It is most accurate to actually measure the distance between the waste floor and the wall with the hole corresponding to the toilet.
