What is the structure of the toilet sewer?

The structure of toilet sewer pipe can be divided into U-shaped structure and linear structure.

U-shaped sewer pipe does not occupy space, and the effect of eliminating odor is quite excellent. It is a common pipe structure in many people's toilets at present. The sewer pipe with linear structure is simple in structure, fast and water-saving, and is often used in public toilets.

Matters needing attention

Entering the water is an important step in cleaning the toilet, and special attention should be paid to the following points:

1, the water seal height of the trap should reach 50mm, so as not to let the air in the drain pipe flood into the room. The drain pipes of floor drain, basin and shower all pass through the floor, and a trap is set below the floor, as shown in the section of P-trap.

2. The floor drain should be about 10mm below the ground, and the drainage flow should not be too small, otherwise it will easily cause blockage.

3. If the floor drain is rough, it is easy to catch hair and sludge, causing blockage, especially easy to breed bacteria.

4. The aperture of the floor drain grate should be controlled between 6 and 8 mm to effectively prevent dirt such as hair, sludge and sand from entering the floor drain.

5. Add a 1 cm railing under the bathroom door. When there is water in the bathroom, it will leak into the sewer from the floor drain. If the floor drain blocks the water, the water will not flow to the living room and other rooms.
