Toilet is divided into horizontal (wall row) and the bottom row (lower row) type two (refers to the way into the water)
How to know what kind of home can be used?
First of all, your understanding of the way the toilet is water is correct.
For how to know their own home can use what kind of water intake of the toilet, you just go to see the bathroom inside the ground, there is no 110mm caliber of the sewage pipe to know. If there is such a sewage pipe on the ground, and the distance between it and the wall at 30 + cm, or 40 + cm, then the bottom row. Conversely, if the sewage pipe is set in front of the wall, then it is wall type. However, many times the wall-type pipe is later installed, not embedded.
Horizontal (wall row) and bottom row (lower row) does not refer to the way of water, refers to the drainage method.
To know which one is used in your home, you can look at the location and placement of the toilet in the bathroom. If the tube (about 11 cm in diameter) to be installed in the toilet seat is erected (the nozzle is parallel to the ground Like a tube erected), you can use the bottom row,
If it is horizontal (the mouth parallel to the wall, like a tube on the ground) is to use the horizontal.
