Add a bathroom to the room on the second floor, you can t chisel the floor slab on the first floor,

The same is true for the trap, but the pit should also be heightened, and the elbow can be placed on the outer wall.

The floor slab on the first floor cannot be opened, so that when arranging the sewage pipe of the toilet or squatting pit, the ground needs to be raised by about 12cm (only the area of the squatting pit), so that the sewage pipe can be buried;

The exterior wall placement can be placed, but whether your house is a self-built house in your hometown or a high-rise house in the community; If it is a self-built house, it is okay, because the aesthetics of the appearance is controlled by itself, and if it is a house in the community, this is related to whether the property is allowed or not;

What needs to be paid attention to when putting it on the outer wall is a direction of the position of the pipe mouth and the wall opening, and the perforation method should be high inside and low on the outside when punching; Only in this way can we ensure that when it rains, the water on the wall will flow directly down and will not be poured into the house; Even if it can be placed on the exterior wall, it is necessary to deal with the problem of where the sewage pipe is discharged, and do not discharge it directly into the soil or flowers, if it is very hot in summer, it may cause a smell, so you must take care of it.

You can go through the sewer outside the wall, and the door of the bathroom is set to open outward, that is, people use the sliding door when they want to enter the bathroom. The door is equipped with steps to increase the height, and you can make a squatting toilet or toilet at will.

The toilet with a wall row is that the drain pipe outlet is on the wall, so that the ground does not need to be raised, and the ground must be raised to install the squatting poop, because the squatting itself is more than 20 centimeters high and has to be embedded in the ground.

Toilet sewage, you can connect the pipe to another bathroom sewer riser, this is more troublesome, if you can directly punch a hole outside the wall to increase the height of the squatting pit, two elbows to get it.

If there is a sewage pipe on the second floor, you can increase the height of the bathroom in the room on the second floor, and connect the sewer pipe to the sewage pipe on the second floor.
