A "hole" and the water tank are in the back, flushing, but also with the water when the somersault up, then the water appeared on a whirlpool to suck in the filth. Personally feel that the latter way looked too dirty, do not know this drainage is the structure with the squatting or related to the structure of the tank? I see online squatting device before / rear, front / rear flush, What kind of "hole" in front of the tank in the back of the structure called what?
Into the water pipe in the back, called behind the drainage in the back, called after the out, in front of the called before the out
Into the water pipe in the back, called backward
You are called back and forth (actually out of the mouth on the other side of the hole). If it is your home sewer comes with water seal, then you do not need to squat squat, and directly into the back before the out (this squatting will be very short, about 10 cm high). Buy squatting to the business when you know your outlet from the walls and how many centimeters on the line, they will tell you how to buy. Generally ranging from 20-200, it is best that the kind of all-ceramic, ranging from 50-200.
Squat the toilet in the front of the sewage hole, that is, urine when the urine directly facing the sewage hole. And washed the feces of water from the back of the buttocks washed forward. General old-style squatting pan is flushed. Its shortcomings are obvious, feces away from the sewage hole slightly away, the water is relatively large.
