The difference between the front pit and the back pit

There is only one difference between the front squat pit and the back squat pit, that is, the position of the drain. The position of the drain refers to the end of the squatting pipe, not the "pothole" you see. Details are as follows:

The front squat pit refers to the squat pit where the drain is far away from the wall, and the rear squat pit refers to the squat pit where the drain is close to the wall.

First, the front squat pit

1, front squat pit without trap: This kind of front squat toilet, with the drain in the front and without trap, will stink.

2. Front squat pit with trap: the toilet is in the back and the drain is in the front, which is not smelly and beautiful.

Second, the back squat pit:

2. The back squat pit has a trap: the hole for defecation is in front, and the eyes can just see the hole.

Extended data:

The reason why there are front squat pits and rear squat pits is determined according to the design of the decoration pipeline, whether to use front squat pits or rear squat pits.

Under normal circumstances, when the distance from the center of the sewer pipe to the wall is 340-440 mm, the rear squat pit is selected; When the distance is 440-540 mm, it is designed as a front squat pit.

There is a difference between a squatting pan with a trap and a squatting pan without a trap. In fact, the construction party may install the trap in advance, so the front and rear drainage methods without trap are selected; On the contrary, the construction party did not install the trap in advance, and chose the front and rear drainage with its own trap.
