Toilet drain pre embedded size

The distance between the toilet sewer pipe and the Rose Pavilion is 330 350 from the wall, so that the distance between the center of the toilet drain and the outside of the toilet can be about 420 430, and at least 400. Nowadays, no matter what kind of toilet, the bend and gas have been formed into a whole, so the ground drain should be more than 600 meters from the wall, which is very good for the toilet.

Toilet sewer pipe installation.

1. After the installation of the water pipe, the pressurization test must be carried out: the pressurization test is generally carried out under the condition of double water pressure, and there should be no water leakage in the test.

2. A simple test method without pressurization, but it is not completely feasible.

1) Close the main valve of the water pipe. 2) Turn on the faucet in the room for 20 minutes, make sure there is no more water dripping and turn off all the faucets.

3) Turn off the water inlet switch of equipment with water storage function, such as toilet tanks and washing machines.

4) Open the main valve of the water pipe.

5) 20 minutes after opening the main valve, check whether the water meter is moving, including slow walking. If there is movement, it is a water leak. If you don't move around, you'll probably be fine.

If there is a problem with the water meter or if the water pipe is slightly percolated, it may be difficult to determine. Therefore, it is recommended that the water pressure test experiment must be carried out after the construction, generally 8 kg, and the time is 20-30 minutes.

3. Water pipe direction: It is recommended that the water pipe go to the top is the safest. The main reason is that most of the waterway reconstruction is done by dark pipes, and the characteristic of water is that water flows to a lower place.

If the pipeline goes underground, it is difficult to find the leakage in time once it occurs, and the leakage will only be found if the water overflows or the floor is deformed and leaks downstairs, and it is difficult to find the leakage because the water pipe is buried in the dark. At this time, the huge loss is irreparable, and even seriously affects the friendly neighborly relationship; If the water pipes go to the top, it may be more expensive to change the water, but as a long-term investment, it is worth it. Even if the water pipe goes to the top, even if the water leaks, it can be found in time, which is convenient for maintenance and the loss is small.

If it is the size of the center from the wall, 65 cm for squatting and 40 cm for sitting, this is the most common size.
